8 Οκτ 2014 · RNA is one of the major biological macromolecules essential for life. It has several types that serve different functions. Messenger RNA (mRNA) carries genetic information from DNA to the ribosomes for protein synthesis. Ribosomal RNA (rRNA) is the catalytic component of ribosomes and is involved in protein translation.

24 Ιουλ 2014 · Three types of RNA: • Messenger RNA (mRNA) • An RNA molecule that carries copies instructions for the assembly of amino acids into proteins from DNA to the rest of the cell. Codons • three-nucleotide sequence on messenger RNA (mRNA) that codes for a single amino acid.
The first step involves RNA polymerase, an enzyme that unwinds and unzips the double helix to access a protein-coding gene. The gene's DNA sequence is used as the template for transcribing an RNA copy of that gene, which the polymerase assembles from a chain of nucleotides.
6 Functions of RNA You can think of an RNA molecule, as a disposable copy of a segment of DNA, a working copy of a single gene. Most RNA molecules are involved in protein synthesis only. RNA controls the assembly of amino acids into proteins. Each type of RNA molecule specializes in a different aspect of this job.
