What 3 types of RNA that help to build proteins?

Answer 1

There are 3 types of RNA: mRNA; rRNA; tRNA.

mRNA, or Messenger RNA, is a copy made from a template piece of DNA, this will encode (every 3 nucleotides makes up a codon which can be read as an amino acid, for example CGA is the codon for an arginine) for the protein that you wish to make.

rRNA, or Ribosomal RNA, is made of 2 subunits, a 50s and 30s (s is just a measure of size), that are combined to make a ribosome. A ribosome is the site in which the protein is synthesized (it contains all the elements necessary to make protein).

tRNA, or Transfer RNA, is what actually reads the mRNA and makes the protein by recruiting and adding the necessary amino acid that the mRNA codes for.

Answer 2

The three key forms of RNA are messenger RNA, ribosomal RNA, and transfer RNA. Protein building occurs in two steps: transcription and translation.

In transcription, mRNA is designed off a DNA strand in the nucleus. The mRNA exits the nucleus.

In translation, rRNA forms a ribosome complex, which by weight is 60% rRNA and 40% protein. The ribosome reads through the mRNA (the transcript) by passing the mRNA through its center and tacks on amino acids carried by tRNA, matching the tRNA anticodons to the mRNA codons. The resulting chain of amino acids is one polypeptide. One or more polypeptides is called a protein.

Answer 3

Messenger RNA (mRNA) carries the genetic information from DNA to the ribosome. Transfer RNA (tRNA) carries amino acids to the ribosome and helps in protein synthesis. Ribosomal RNA (rRNA) is a component of the ribosome where protein synthesis occurs.

Answer 4

Ribosomal RNA, mRNA, messenger RNA, mRNA, and transfer RNA, tRNA.
