Question

I just need some help explaining this, I'm not looking for answers. :)
One of the central themes in biology is how DNA, RNA, and proteins are related. Describe how genetic information flows between those types of molecules. Include the results of the processes of transcription and translation.

Answer 1

Can you define the three? @LeeEtchison

Answer 2

@LeeEtchison I mean just the most basic definition of each.

Answer 3

DNA: the carrier of genetic info, a double helix, functions sorta like an archive.
RNA: carries instructions from DNA to control the synthesis of proteins.
Proteins: made of polymers of amino acids, joined together by peptide bonds.
Like that, you mean?

Answer 4

@LeeEtchison Yep. You are basically at your answer already. Now, what are transcription and translation and where should they go in your above post.

Answer 5

Transcription is the process by which the information in a strand of DNA is copied into a new molecule of mRNA
Translation: when the genetic code carried by mRNA is decoded to produce the specific sequence of amino acids in a polypeptide chain
But how would I string all those together?

Answer 6

@LeeEtchison So, if transcription is getting the info from DNA to RNA, where would you insert that into your first statement? Between DNA and RNA, or RNA and proteins?

Answer 7

The former.

Answer 8

Yep. So, you current have told me that DNA functions a molecular library of instructions, and that this is transcribed into RNA. RNA being like making a copy of a instruction and removing it from the library.

Answer 9

Okay, I think I got this now. Thanks! :)

Answer 10

@LeeEtchison No problem. You knew the answer, just needed a bit of help formatting it.
