what does RNA polymer do?

Answer 1

(Fyi, it should be "an" RNA polymer.) An RNA polymer is just a long sequence of nucleotides strung together. RNA is used for three things. First, mRNA (messenger) is transcribed from DNA (like making a copy) by a polymerase. This mRNA then travels to a ribosome (which is protein plus rRNA (ribosomal)). Here it is translated from the nucleotide code to the amino acid sequence. tRNA does the translating by matching three nucleotides to an amino acid. The ribosome holds the amino acid together until it is done forming.

Answer 2

Ribonucleic acid (RNA) is a nucleic acid polymer consisting of nucleotide monomers. RNA nucleotides contain ribose rings and uracil unlike deoxyribonucleic acid (DNA), which contains deoxyribose and thymine. It is transcribed (synthesized) from DNA by enzymes called RNA polymerases and further processed by other enzymes. RNA serves as the template for translation of genes into proteins, transferring amino acids to the ribosome to form proteins, and also translating the transcript into proteins.
