Which type of RNA reads the genetic code?

mRNA
During translation, which is the second major step in gene expression, the mRNA is “read” according to the genetic code, which relates the DNA sequence to the amino acid sequence in proteins (Figure 2).

What reads the genetic code?

Genetic code is the term we use for the way that the four bases of DNA–the A, C, G, and Ts–are strung together in a way that the cellular machinery, the ribosome, can read them and turn them into a protein. In the genetic code, each three nucleotides in a row count as a triplet and code for a single amino acid.

What types of RNA are coding?

Coding-RNA (messenger RNA; mRNA) Messenger RNA (mRNA) carries the genetic code from DNA in a form that can be recognized to make proteins. The coding sequence of the mRNA determines the amino acid sequence in the protein produced.

What is the function of R RNA?

The primary function of rRNA is in protein synthesis – in binding to messenger RNA and transfer RNA to ensure that the codon sequence of the mRNA is translated accurately into amino acid sequence in proteins.

What does RNA do during protein synthesis?

Specifically, messenger RNA (mRNA) carries the protein blueprint from a cell’s DNA to its ribosomes, which are the “machines” that drive protein synthesis. Transfer RNA (tRNA) then carries the appropriate amino acids into the ribosome for inclusion in the new protein.

What is non-coding RNA genes?

A non-coding RNA (ncRNA) is an RNA molecule that is not translated into a protein. The DNA sequence from which a functional non-coding RNA is transcribed is often called an RNA gene. It is also likely that many ncRNAs are non functional (sometimes referred to as junk RNA), and are the product of spurious transcription.

Where is rRNA translated?

ribosome
ribosomal RNA (rRNA), molecule in cells that forms part of the protein-synthesizing organelle known as a ribosome and that is exported to the cytoplasm to help translate the information in messenger RNA (mRNA) into protein.

Which RNA polymerase works on mRNA?

RNA polymerase II
Because RNA polymerase II is responsible for the synthesis of mRNA from protein-coding genes, it has been the focus of most studies of transcription in eukaryotes.

What RNAs do each eukaryotic RNA polymerase produce?

Eukaryotes have three different types of RNA polymerases: RNA polymerase I (Pol I), used to produce the large ribosomal subunit; RNA polymerase II (Pol II), used to produce the protein-encoding RNAs and the micro RNAs; RNA polymerase III (Pol III), used to produce each of the tRNAs and the small ribosomal RNA subunit.
