Question 1
1 / -0

A distinct mechanism that usually involves a short segment of DNA with remarkable capacity to move from one location in a chromosome to another. What is this called as?

A
DNA replication

B
DNA transposition

C
DNA hybridization

D
DNA recombination

Solution

The final method of changing the DNA in a genome is called transposition, which is the movement of DNA from one location to another. Segments of DNA with this ability to move are called as transposable elements.
Question 2
1 / -0

Gel electyrophoresis is used for

A
Construction of recombinant DNA by joining with cloning vectors

B
Isolation of DNA molecule

C
Cutting of DNA into fragments

D
Separation of DNA fragments according to their size
Question 3
1 / -0

The two polynucleotide chain in DNA are:-

A
Semiconservative

B
Parallel

C
Discontinuous

D
Antiparallel

Solution

The two polynucleotide chain in DNA are having opposite polarity and thus are arranged antiparallel i.e., if one chain is having polarity from 5'-->3' then other will have a polarity of 3'-->5'.
So, the correct answer is 'Antiparellel'.
Question 4
1 / -0

Assertion: DNA polymerase-I acts as proofreader.

Reason: DNA polymerase-I removes mismatched nucleotides.

A
If both the assertion and the reason are true and the reason is a correct explanation of the assertion

B
If both the assertion and reason are true but the reason is not a correct explanation of the assertion

C
If the assertion is true but the reason is false

D
If both the assertion and reason are false

E
If the assertion is false but reason is true
Question 5
1 / -0

Which one of the following triplet codes, is correctly matched with its specificity for an amino acid in protein synthesis or as 'start' or 'stop' codon : -

A
UCG Start

B
UUU Stop

C
UGU Leucine

D
UAC Tyrosine

Solution

UGU → cistine
UAC → tyrosine
UCG → serine
UUU → phenylalanine
UAG, UGA, UAA → are stop codons
UAG → start codon.

So, the correct answer is 'D'.
Question 6
1 / -0

Twenty five micrograms ($$25 \mu g$$) of DNA amounting five micromole ($$5 \mu$$mole) was cut using a specific restriction enzyme into two pieces. Subsequently, when it was analyzed on an agarose gel it showed two bands of 200 bp and 800 bp. If the length of the original DNA was 1000 bp, Which of the following options best quantifies each band?

A
200 bp band : $$\mu$$mole - 5, $$\mu g$$ - 5; 800 bp band : $$\mu$$mole - 5, $$\mu g$$ - 20

B
200 bp band : $$\mu$$mole - 1, $$\mu g$$ - 5; 800 bp band : $$\mu$$mole - 4, $$\mu g$$ - 20

C
200 bp band : $$\mu$$mole - 5, $$\mu g$$ - 25; 800 bp band : $$\mu$$mole - 5, $$\mu g$$ - 25

D
200 bp band : $$\mu$$mole - 1, $$\mu g$$ - 25; 800 bp band : $$\mu$$mole - 1, $$\mu g$$ - 25
Question 7
1 / -0

Genetic information in a DNA molecule is coded in the

A
sequence of nucleotides

B
base pairing

C
turning pattern of the helix

D
portion of each base present

Solution

It is the sequence of nucleotides that transmit genetic information to proteins; i.e., it determines the sequence of amino acids in a polypeptide chain that forms each and every protein made in the cell. Also, the expression of each and every protein within each cell type is determined by multiple nucleotide sequences that form promoters and various enhancer and repressor sequences. Thus, the genetic information in a DNA molecule is coded in the sequence of nucleotides.

Thus the correct option is "(A) sequence of nucleotides".
Question 8
1 / -0

In the double helix model of DNA as proposed by J. D. Watson and F.S.C. Crick, each base pair is how far from the next base pair:

A
0.034nm

B
0.34nm

C
3.4nm

D
34nm
Question 9
1 / -0

Production of a human protein in bacteria by genetic engineering is possible because

A
Bacterial cell can carry out the RNA splicing reactions

B
The mechanism of gene regulation is identical in humans and bacteria

C
The human chromosome can replicate in bacterial cell

D
The genetic code is universal
Question 10
1 / -0

Assertion: The tRNA molecules possess anticodons.

Reason: It needs the message in form of codon.

A
If both the assertion and the reason are true and the reason is a correct explanation of the assertion

B
If both the assertion and reason are true but the reason is not a correct explanation of the assertion

C
If the assertion is true but the reason is false

D
If both the assertion and reason are false

E
If the assertion is false but reason is true

Solution

tRNA has anticodons which read the message expressed in the form of codons in mRNA and occupy a specific place on mRNA. tRNA also recognises the amino acids.
So, the correct answer is 'If both the assertion and reason are true but the reason is not a correct explanation of the assertion'
