How do mRNA and the tRNA read each other?

Answer 1

Ribosomes translate messenger RNA (mRNA) into protein in the cytosol, outside the nucleus. Many proteins which are destined for exocytosis (released from the cell into the environment) or integration into the cell membrane (for signalling) are made by ribosomes which become associated with the endoplasmic reticulum, or ER, (also in the cytosol). In this case, proteins are translated by ribosomes and simultaneously inserted into the ER, and later transported in vesicles to the cell membrane.

Answer 2

The ribosome takes in the mRNA and for each codon, it matches it up with an anti codon (a C for a G and etc.). Each anticodon has a corresponding amino acid which gets linked to the growing polypeptide chain.

Answer 3

In many (but not all cases) ribosomes look for a binding site called a Shine-Dalgarno (prokaryotes) or Kozak (Eukaryotes) sequence on the mRNA to bind to. But I don't think that is really what you are asking. Once it is bound to the mRNA it looks for a start codon. A codon is a sequence of three base pairs that call for a particular amino acid or instructs the ribosome to start or stop. In this case, it does both. The start codon is AUG which incidentally also codes for Methionine.

Answer 4

mRNA and tRNA complement each other through base pairing. Each tRNA molecule carries a specific amino acid and has an anticodon sequence that is complementary to the codons on the mRNA. This allows the tRNA to "read" the mRNA by pairing its anticodon with the codons on the mRNA during protein synthesis.

Answer 5

Ribosomes read mRNA through the amino acids and proteins in its sequence. mRNA may be read either a few or many times, depending on its stability.

Answer 6

translation :)
