Question

A protein comprises totally 400 amino acids given this data, asses the total number of nucleotides on the mRNA and also the number of ATP, the number of peptide bonds formed. The number of translocations and number of Ribosomes respectively are
A.1203, 400, 399, 399 and 1
B.1200, 300, 400, 399 and 400
C.1203, 400, 399, 399 and 400
D.1200, 800, 400, 399 and 1

Answer 1

Hint: During protein synthesis, the mRNA and tRNAs must be moved quickly through the ribosome while unequivocally keeping up the translational reading frame. This is coupled to enormous and little scale conformational modifications in the ribosome, fundamentally in its ribosomal RNA.

Complete answer:
1. On the mRNA three nucleotides structure a codon for the amino acids. It has one start codon, AUG for methionine, all outstanding codon for the polypeptide chain and one of three stop codon UAA, UAG, UGA which doesn't code for any amino acid. In this way, for 400 amino acids, the quantity of nucleotides are
400\[ \times \]3 = 1200 + 1 stop codon=1203 nucleotides.

2. 1 particle of ATP is changed over into AMP + 2Pi to actuate 1 amino acid, so for 400 amino acids 400 ATP is used.

3. A peptide bond is an amide kind of compound bond connecting two sequential alpha-amino acids from C1 of one alpha-amino acid and N2 of another along a peptide or protein chain. In this way, for the 400 amino acid to join, 399 peptide bonds are required.

4. Translocation means the synchronous movement of two tRNAs along with the mRNA by one codon on the ribosome. Thus, for the 400 amino acids, 399 translocations are required.

5. During translation, ribosomal subunits collect together like a sandwich on the strand of mRNA, where they continue to pull in tRNA atoms fastened to amino acids (circles). A long chain of amino acids rises as the ribosome decodes the RNA sequence into a polypeptide or another protein. 1 ribosome is utilized for the translation.

In this way, the right answer is "Nucleotides=1203, ATP= 400, Peptide Bond=399, Translocations=399 and Ribosomes= 1"

So, the correct answer is option A.

Note:
Translation alludes to the way toward making proteins from a mRNA layout.
The grouping of nucleotides on the DNA is converted into the amino acid sequence of proteins and these responses are completed by ribosomes.
Translocation is the chromosomal movement, in which a chromosomal section is moved starting with one position then onto the next either inside a similar chromosome or to another chromosome.
