Biology: Transcription and Translation Overview

June 132010

http://www.mindbites.com/lesson/1460-biology-transcription-and-translation-overview

To understand transcription and translation, Professor Wolfe states that you must first understand the “central dogma” that DNA makes RNA and RNA makes proteins. But how is this infromation communicated? Through transcription, which is the process where DNA information is coded into RNA, and translation which is the process of converting the mRNA molecule by ribosome into polypeptide strand. This process happens in both prokaryotic and eukaryotic cells, but in Eukaryotic cells translation takes place outside of the nucleus. Professor Wolfe also discusses the three different types of RNA, mRNA, tRNA, and rRNA. He explains rRNA and how is used to help translate the mRNA.

This lesson is perfect for review for a CLEP test, mid-term, final, summer school, or personal growth!

Taught by Professor George Wolfe, this lesson was selected from a broader, comprehensive course, Biology. This course and others are available from Thinkwell, Inc.

Score Higher Than 28/30 on TOEFL iBT Integrated Writing by Following Five Simple Steps

June 92010

http://www.bettertoeflscores.com Get helpful, specific, and free tips to pass the TOEFL iBT. And tell all your friends! See you at my TOEFL iBT Blog,

Here is a short article to help you improve your writing and speaking skills for the TOEFL iBT:

Comma Splices, Run-ons, and Fragments: Three TOEFL iBT Grammar Errors You Do Not Want to Make! By Michael Buckhoff

Good basic sentence structure requires that you use appropriate punctuation, have clear sentence boundaries, and write in complete ideas. Therefore, when you are completing your independent and integrated writing tasks, you need to avoid comma splices, run-on sentences, and fragments, all of which are common sentence structure errors in writing for both native and nonnative speakers of English.

The TOEFL iBT human raters will grade your essay partly based on your grammar usage. If you use only basic grammar accurately, you will not get a high score; if you use advanced grammar with errors, you will also not receive the highest possible score. Therefore, having good control of your sentence structures, which means avoiding comma splices, run-on sentences, and fragments, will help you to score higher on TOEFL iBT writing.

Having problems with comma splices, run-ons, and fragments are common errors for both non-native and native speakers. A lack of experience writing and getting feedback from ESL/EFL specialists and differences in sentence structure rules from other languages and English cause English learners to have trouble with this type of grammar.

To improve in this area, you need to understand what these errors are, how you should correct them, and where you can get further practice with comma splices, run-ons, and fragments.

A comma splice is when you join two independent clauses together with a comma.
Comma splice: Jake is washing his car, he is getting ready for a long vacation.
Revised: Jake is washing his car because he is getting ready for a long vacation.
Jake is washing his car; he is getting ready for a long vacation.
Jake is washing his car. He is getting ready for a long vacation.
A run-on sentence is when you combine two independent clauses together with no punctuation.
Run-on sentence: Sociology is the study of social groups it teaches students about human nature.
Revised: Sociology is the study of social groups. It teaches students about human nature.
A fragment is when you have an incomplete idea (i.e., dependent clause or phrase) as its own sentence.
Fragment: Fighting against violence can be accomplished. If the government spends enough money in educating the public.
Revised: Fighting against violence can be accomplished if the government spends enough money in educating the public.

What has been the best writing experience you have had?

June 82010


One particular scene had me close to tears. (I’m not a particularly emotional person most of the time.) It was mainly about how my narrator’s wife had been raped, or nearly raped, while they were apart, and she couldn’t bring herself to tell him, but he said he would stand by her and help her to get over whatever it was that was troubling her.

And then I cut it in the second or third draft. Because it didn’t move the story forward enough, and didn’t quite fit with what I’d decided about the bad guys who might’ve done whatever it was to the wife.

Nobody said this was easy, did they?

Hey, has anyone had experience on writing a book?

June 52010

I know all about the idea of writing about what you know. Where do you start is the question. How would you start and finish a book.
I plan on writing one in the next year about my life. which is filled with twist and bends.

I usually start by picking a topic that i like then i just let it sit in the back of my head. I am only an 8th grader but i like writing. So yea i pick a topic, then i form the characters around my life, my friends and people that i know. If you are still in school, look around at the way people do things and the start making up your characters. that really helps me. I usually start with something happening. in my last story, it was bout a little girl that had lost her family in a plane crash. she was completely blind, then she meets someone that really likes her. she doesn’t know this yet, but he is actually planning on stealing her and never giving her back. and the i ended with, " Nothing would change. I was still wrapped in his arms. Forever. Nothing could change that and i was stuck here forever. And i was perfectly happy."

I have a homework assignment.Who has experience with writing business proposals please?

May 302010

Ok for my homework assignment I’m suppost to act like I’m going to come up to my teacher as a proposal business partner. basically a three page outline of a make believe restaurant. I was hoping if someone with experience could help shoot me some guide lines and ideas of what should be importantly added as if it were real. What would you expect to hear from me? I would highly appreciate it, thank you.

When writing this for a proposed partnership you should include some information about the business. I would also suggest writing about the following:
-who is going to own each percentage of the business
-what those people’s responsibilities are in the business operation
-what happens to resolve disagreements
-what happens if someone chooses to leave the partnership
-salary/profit dispersion
-how you will raise additional money if it is needed

Those are just a few suggestions. Just keep in mind when writing your paper that proposals and business agreements in general are written to protect the parties involved as well as limit surprises down the road. I hope this helps.

I’m looking for a contract job — but the first thing recruitment agencies ask for is my CV.

Why is my CV so important?

Getting an interview can depend on how good your CV is. It is your opportunity to show an employer that you’ve got the skills and experience needed and that you are the right person for the job.

So, how long should my CV be?

Your CV should be no more than two pages long & easy to read with spaces between each section.

& What should I include in my CV?

You need to start with your Personal profile
This section should only be a few lines long, but must spark the reader’s interest. Be brief as you can highlight examples of your skills in later sections. You may include the following:

Name, address and contact details.
Skills and qualities
Then there’s your Employment history
Start with your present or most recent job and work backwards, ideally using bullet points as these are much clearer. You may include the following:
Each employer
The dates you worked for them
The job title
Your main duties

You then move on to Education and training

Start with your most recent study and go back to the qualifications you got at school.. You may include the following:

The university, college or school you went to
The dates the qualifications were awarded and any grades
Any other courses, if they’re relevant

You will also need to mention Hobbies and interests
Employers like to read about your interests, as it can give them an idea of your strengths and what you’d be like to work with.

You may need to have Additional information
If you need to add anything else that’s relevant, such as a gap in your employment history, you could include a further section titled “Additional Information”.

& finally there are your References
You should state that references are available if required, although you do not need to include referees’ contact details on your CV.

Be positive — don’t be too modest and don’t lie about your experience. Positive thinking is vital in securing your next contract.

Thanks for the information — it’s really useful.
