What are the domains of mRNA?
The key structural domains of mRNA are the 5¢ cap (also known as the 7methylguanosine cap), the 5¢ and 3¢ UTRs, the coding sequence and the poly(A) tail.
Which are the 4 sites of tRNA?
Four binding sites are located on the ribosome, one for mRNA and three for tRNA. The three tRNA sites are labeled P, A, and E. The P site, called the peptidyl site, binds to the tRNA holding the growing polypeptide chain of amino acids.
What are the structures and functions of mRNA rRNA and tRNA?
Messenger RNA (mRNA) molecules carry the coding sequences for protein synthesis and are called transcripts; ribosomal RNA (rRNA) molecules form the core of a cell’s ribosomes (the structures in which protein synthesis takes place); and transfer RNA (tRNA) molecules carry amino acids to the ribosomes during protein …
How does arginine rich domains coordinate mRNA maturation events?
SR proteins and arginine methylated domains contribute to the coupling of different RNA maturation events by modulating interactions of various components of the mRNA processing complexes with each other and with RNA.
What is the functional form of tRNA?
The correct option is ‘Transport specific amino acids to specific sites on the mRNA’.
What is P site and A-site?
The P-site (for peptidyl) is the second binding site for tRNA in the ribosome. The other two sites are the A-site (aminoacyl), which is the first binding site in the ribosome, and the E-site (exit), the third. During protein translation, the P-site holds the tRNA which is linked to the growing polypeptide chain.
What are the four types and functions of RNA?
4 Types of RNA
- Messenger RNA (mRNA) mRNA is translated into a polypeptide. (
- Transfer RNA (tRNA) tRNA will bind an amino acid to one end and has an anticodon on the other. (
- Ribosomal RNA (rRNA) Ribosomal RNA (rRNA) helps facilitate the bonding of amino acids coded for by the mRNA. (
- Micro RNA (miRNA)
