How is the role of DNA and messengerRNA primarily to store information?

Answer 1

DNA and mRNA are both made up of four different discrete bits of information called nucleotides. Adenine, Guanine, Cytosine, and Thymine are the subunits of DNA. In mRNA, Thymine is replaced by Uracil. Think of these units of DNA and mRNA as a binary code like what computers use. 0101011. That kind of thing. Different proteins use the sequence of these four different bits to unravel a "code". This code is then transfered to mRNA which allows the code to be cracked by tRNA and allow for the carrying out of the instructions contained in the code. So although DNA is only a series of interlocking bits of nucleotides, the order of these nucleotides forms a genetic code which can be used by other molecules as instructions to form proteins. It isnt the DNA and mRNA which stores the information directly. It is the code contained in DNA and mRNA which stores the information.

Answer 2

DNA consists of genes, strings of thousands of nucleotides that code for the amino acids in the order necessary to make specific proteins. Instead of doing all the work by itself, however, DNA transcribes these codes onto mRNA for a practical purpose: to construct the proteins.

Answer 3

Well, DNA is one long code, for protein synthesis, and the proteins that your DNA code for are the proteins that say, make your hair brown, or your eyes blue. and messenger RNA acts as a blueprint of the DNA, and takes the code to the ribosome where it meets the tRNA and that's where the protein is assembled.
