technology with their activity. Select the incorrect combination of enzyme and its
activity.

A:-T7 DNA polymerase : DNA polymerase and 3' exonuclease activities
B:-Poly(A) polymerase : Adds AMP from ATP to the 3' end of mRNA

Question32:-Few terms have been explained below. Select the correctly explained
ones.
(i) Multiple factor hypothesis explains variation in complex phenotypes such as
height, weight,
and disease susceptibility.
(ii) Broad-sense heritability is the proportion of the total phenotypic variance that is
due to
genetic factors.
(iii) Fitness is the number of offspring left by an individual, often compared with the
average of
the population.
(iv) QTL are associated with a particular phenotypic trait, which varies in degree
and which can
be attributed to polygenic effects.

A:-Only (i) and (iv) are correct
B:-Only (iii) and (iv) are correct
C:-Only (i) and (iii) are correct
D:-All are correct

Correct Answer:- Option-D

Question33:-Though fusion tags have been very helpful in the detection and
isolation of target recombinant proteins, they may interfere with the biological
function of the target protein eventually. Hence, they are generally removed by
cleaving a short linker amino acid sequence joining the fusion tag with the target
protein using appropriate protease enzymes. Which of the following is a commonly
used protease for performing the above cleavage?

A:-Trypsin

B:-Tobacco Etch Virus Protease

C:-Alpha peptidase

D:-None of the above
