Is it true that RNA carries the code made by DNA?

Question

My biology reference book states that RNA is the messenger.

Answer 1

In the case of mRNAs( messenger RNA) it's correct.RNAs are the transcripts of the DNA after the translation of mRNA the message of DNA is translated into proteins.However we have other RNAs such as microRNAs,tRNAs and rRNAs,.. which they won't be translated to the protein.These ones have regulatory, transferal and structural functions respectfully.So they are not just the messenger.

Answer 2

Ribonucleic acid or RNA is a nucleic acid, consisting of many nucleotides that form a polymer. Each nucleotide consists of a nitrogenous base, a ribose sugar, and phosphate. RNA which plays several important roles in the processes of translating genetic information from deoxyribonucleic acid (DNA) into proteins. One type of RNA acts as a messenger between DNA and the protein synthesis complexes known as ribosomes, others form vital portions of the structure of ribosomes, act as essential carrier molecules for amino acids to be used in protein synthesis, or change which genes are active.
DNA stands for deoxyribonucleic acid, while RNA stands for ribonucleic acid. RNA is very similar to DNA, but differs in a few important structural details: RNA is usually single stranded, while DNA is usually double stranded. RNA nucleotides contain ribose while DNA contains deoxyribose (a type of ribose that lacks one oxygen atom), and RNA uses the nucleotide uracil in its composition, instead of thymine which is present in DNA. RNA is transcribed from DNA by enzymes called RNA polymerases and is generally further processed by other enzymes and by non-coding RNAs.


hope this is of some help to you:)) enjoy learning more about biology:)))

Answer 3

It may surprise you but in eukaryotes, post-transcriptional RNA editing can change RNA quite a bit, in some cases, one base is exchanged for another in the middle of a characteristic sequence; introns are spliced out of the primary transcript; chemical alteration of nitrogenous bases (in tRNAs), addition of 5' cap etc are only a few of numerous examples of RNA editing that is independent of the DNA sequence.

Answer 4

mRNA is made to be a copy of the DNA's instructions. mRNA is messenger RNA. It takes the instructions out to a ribosome in the cytoplasm, and that's the place where the proteins are made. tRNA brings the amino acids to the ribosome to build the protein.

Answer 5

yes this is true.
