The codon AUG codes for: MCQ with Answer and Explanation

The codon AUG codes for:
A. Methionine
B. Glycine
C. Alanine
D. Arginine
Answer: Option A
Solution (By JKSSB Mock Tests)
AUG is the initiation codon and codes for methionine in eukaryotes (formylmethionine in prokaryotes). It signals the start of translation. Arginine codons include CGU, CGC, etc. Alanine is coded by GCU, etc. Glycine by GGU, etc. The genetic code is degenerate, meaning multiple codons can code for the same amino acid, but AUG is unique as the initiator.

Question #1
The disease caused by iodine deficiency is:
A. Goiter
B. Rickets
C. Beri-beri
D. Anemia

Correct Answer: Option A


Explanation:
Iodine deficiency impairs thyroid hormone synthesis, leading to elevated TSH and enlargement of the thyroid gland (goiter). Iodized salt prevents it.

Question #2
The number of ATP molecules produced from one glucose molecule during aerobic respiration is approximately:
A. 18
B. 2
C. 4
D. 36-38

Correct Answer: Option D


Explanation:
In eukaryotes, complete oxidation of one glucose molecule via glycolysis, Krebs cycle, and electron transport chain yields a net of about 36-38 ATP molecules (depending on shuttle systems). Glycolysis yields 2 ATP, Krebs 2 ATP, and oxidative phosphorylation 32-34 ATP. This is much higher than anaerobic respiration (2 ATP).

Question #3
The technique used to produce a large number of identical copies of a specific DNA fragment is:
A. PCR
B. Gel electrophoresis
C. DNA sequencing
D. Microarray

Correct Answer: Option A


Explanation:
Polymerase chain reaction (PCR) amplifies a specific DNA segment exponentially using primers, DNA polymerase (Taq), and thermal cycling. Gel electrophoresis separates DNA by size, sequencing determines base order, microarray analyzes gene expression. PCR is crucial in cloning, diagnostics, and forensics.
