How do I replicate this teams of DNA? ATTCGGCAAG?

Question

Super confused 

Answer 1

DNA replication is a simple process that can be easily accomplished if you know your ABCs!!! Or in this case, your AGTC's. DNA has a certain language that it is written in, much like English for us that speak English in America or Spanish for those that speak Spanish in America. DNA is also a ribonucleic acid with RNA being part of the same ribonucleic acid family. Think of DNA as spoken English and RNA as written English and the enzymes that help these processes as the typist in a court room that types the minutes of every court case that comes his/her way. When DNA replication occurs, we begin with DNA and end with DNA. Essentially, English was spoken towards us in the court room and then a perfect copy of that spoken English is presented back to the judge and lawyers with no mistakes. DNA transcription, another process, begins with DNA and ends with RNA. Here, you make a transcription of the spoken English and transcribe it into written English. Here, the alphabet changes but is still English, just different letters. Translation, taking RNA to protein, completely changes the language from written English to written Spanish and has no letters (A,G, U, T, or C) that were used in ribonucleic acid language.

Getting back to the problem, the DNA strand that you had to use for DNA replication was ATTCGGCAAG. A rule in Biology exists that states you must have the same amount of A as you do T and the same amount of C that you do G. In other words, that means wherever there is a C on one strand, the replicating strand must have a G and vice versa. Same applies to A and T.

With all this knowledge, the sister replicate of ATTCGGCAAG would be TAAGCCGTTC.

Hope this helps!

Answer 2

Hello, Sierra.  I think I can help.  When DNA makes a copy of itself (replicates), it opens up and each side of the DNA helix pairs up with loose nucleotides that have specific nitrogen bases.  Adenine only pairs with Thymine and Guanine only pairs with Cytosine.

 

In your question, you only show one side of the DNA helix.  Was there another strand too?  If not,  You will show how the specific nitrogen bases can just pair up in the correct order.

 

A always with T

G always with C

 

Since your strand is in the order below, the nitrogen bases would match up in this way:

 

ATTCGGCAAG

TAAGC........

 

Do you think you can finish it now?  Hope that helps.
