Question

In order for protein sysnthesis to occur, which molecules do what? match each item to its role in the process. 1. brings the monomer subunits that are used to RNA build proteins, to the ribosome is a structural component of the ribosome B. RNA 2. 3. brings genetic information to the ribosome D 4. provides a spot for incoming tRNAs (aminoacyl B . small subunit E. P-site F. G. initiation factor RNAs) to bind to the ribosome 5. provides a spot for outgoing tRNA molecules to anticodon leave the ribosome 6. provides a binding site for mRNA to attach to H aminoacyl tRNA symthetase 7. provides a spot for amino acids to be joined to 8. region of the mRNA that interacts directly with L. 7-methylguanosine cap the ribosome poly-A tail Esite each other K. RNA M. elongation factor N. release factor O. A-site P. region of the tRNA that interacts directly with mRNA 9. 10. attaches the correct amino acids to the tRNA 11. binds to the stop codon 12. responsible for binding to the 40S subunit and codon Q mRNA protecting mRNA from being destroyed MacBook Air FS F7 FS

Explanation / Answer

1. The tRNSA or tansfer RNA brings the monomer subunits required for synthesis of polypeptide or protein to ribosomes . The statement matches with A.

2. Structural component of ribosome is small subunit. The ribosomes contain large and small subunits. The statement matches with D.

3. The genetic information is carried by the mRNA to ribosomes during protein synthesis. The statement matches with Q.

4. The small subunits contains three spots for attachement during synthesis and for exit of tRNAs after addition of amino acid. A site is amino acyl site, P - site is polypeptide site and E - site for exit of tRNA. The first amino acid carried by aminoacyl tRNA synthetase is released into P - site. The statement matches with E.

5. Small subunit, E - site provides the spot for tRNA leaving the ribosome or to exit. The statement matches with J.

6. The initiation factor bound to ribosome enables the binding of mRNA. The statement matches with G.

7. Small subunit of ribosome with A - site or amino acyl site provides spot for attachment of amino acids. The statement matches with O.

8. The region of mRNA interacting with tRNA is codon. The codon of mRNA forms complamentary base pairing with anticodon of tRNA. The statement matches with P.

9 . The region of tRNA interacting with mRNA is anticodon. The codon of mRNA forms complamentary base pairing with anticodon of tRNA. The statement matches with F.

10. Amino acyl tRNAS synthetase is an enzyme that attaches a specific amino acid to the corresponding tRNA. The statement matches with H.

11. Termination of protein synthesis occurs when the mRNA reaches the stop codons UAA, UAG and UGA. The release factor binds to stop codon and releases the polypeptide chain indicating the completion of protein synthesis or termination of translation. The statement matches with N.

12. A poly A tail is responsible to protect the mRNA from degradation. Poly A tail binds to the 40S subunit of ribosome. The statement matches with I.
