A
Crick

B
Watson

C
Franklin

D
Khorana
Question 3
1 / -0

Transformation experiments in bacteria were first performed by

A
Macleod

B
Griffith

C
Pasteur

D
Meselson and Stahl
Question 4
1 / -0

Isotopes used in proving semi-conservative replication of DNA were

A
$$^{14}N, ^{14}C$$

B
$$^{14}C, ^{31}P$$

C
$$^{14}N, ^{15}N$$

D
$$^{14}N, ^{31}P$$
Question 5
1 / -0

Type of coiling in DNA is

A
Right handed

B
Left handed

C
Zigzag

D
Opposite
Question 6
1 / -0

DNA is present in

A
Nucleus

B
Chloroplasts

C
Mitochondria

D
All the above

Solution

Correct answer: D
Explanation:
• DNA is mainly found in the nucleus, however, extranuclear DNA is found in certain organelles.
• Mitochondrial DNA is significant in maternal inheritance, whereas chloroplast DNA consists of genes important for photosynthesis.
Hence, DNA is present in all of the above.

A
Overlapping genes

B
Degeneracy of genetic code

C
Wobbling of codons

D
Universality of codons
Question 8
1 / -0

Genetic code translates the language of __________________.

A
Amino acids into that of RNA

B
RNA into that of protein

C
Protein into that of DNA

D
RNA into that of DNA
Question 9
1 / -0

Correct sequence of code transfer during polypeptide formation is

A
DNA, mRNA, tRNA and amino acids

B
DNA, tRNA, rRNA and mRNA

C
mRNA, tRNA, DNA and amino acids

D
rRNA, DNA, mRNA and tRNA
Question 10
