Question

Polymerization of amino acids into a polypeptide requires energy. In terms of chemical thermodynamics, the chemical energy for peptide bond formation in translation technically comes from: hydrolysis of GTP hydrolysis of ATP translocation of the ribosome as it moves along the mRNA ribosomal RNA (rRNA) secondary structure transcription of the mRNA that is being translated Transfer RNA (tRNA) is a ribonucleic acid about 50-60 nucleotides long. When a tRNA gets "charged" by covalent addition of its cognate amino acid, to which end of the tRNA is the amino acid attached? the 5' end the 3' end either the 5' or 3' end, it varies with different tRNA's technically the amino acid is bound to the "anticodon" sequence of the tRNA, not the end of the tRNA The picture below shows a process in gene expression that you would expect to find in: prokaryotes only eukaryotes only both Prokaryotes and Eukaryotes neither prokaryotes nor eukaryotes would be expected to do this If a prokaryotic mRNA contains 2 separate ribosome binding sequences and 3 separate methionine codons. How many individual proteins could it produce during translation? 3 1 2 Cannot be determined with information given DNA

Answer 1

Answer 14)

A is the answer.

Two molecules of GTP are required in single transloaction step during translation. The GTL is responsible for carrying charged tRNA to the ribosome. GTP hydrolysis leads to release energy.

15) B is the right answer.

Explanation:

the 3' end of tRNA carries CAA site. This site jave carboxyl group. This carboxyl group reacts with amino group of amino acid. And this makes the tRNA charged.

16) a is the right answer.

Because polysome is depicted in the figure. The transcription and translation is coupled in this figure. This is the characteristics fetaures of prokaryotes only.
