Question

Match the column:

$\begin{array}{cccc}& \text{Column-I}& & \text{Column-II}\\ \text{(a)}& \text{VNTR}& \text{(i)}& \beta -\text{Galactosidase}\\ \text{(b)}& \text{Lac operon}& \text{(ii)}& \text{DNA ligase}\\ \text{(c)}& \text{Genetic code}& \text{(iii)}& \text{DNA fingerprinting}\\ \text{(d)}& \text{Okazaki fragments}& \text{(iv)}& \text{Unambiguous}\end{array}$

• A. a $\to$ iv, b $\to$ ii, c $\to$ iii, d $\to$ i
• B. a $\to$ iii, b $\to$ i, c $\to$ iv, d $\to$ ii
• C. a $\to$ i, b $\to$ ii, c $\to$ iii, d $\to$ iv
• D. a $\to$ iii, b $\to$ iv, c $\to$ i, d $\to$ ii

Answer 1

The correct option is B a $\to$ iii, b $\to$ i, c $\to$ iv, d $\to$ ii

VNTRs are used in DNA fingerprinting.

$\beta$- galactosidase is one of the enzymes present in lac operon.

The genetic code is unambiguous which means each codon specifies one amino acid only.

Okazaki fragments are joined by DNA ligase.

Hence, the correct match is:
$$\begin{array}{cccc}& \text{Column-I}& & \text{Column-II}\\ \text{(a)}& \text{VNTR}& \text{(iii)}& \text{DNA fingerprinting}\\ \text{(b)}& \text{Lac operon}& \text{(i)}& \beta -\text{Galactosidase}\\ \text{(c)}& \text{Genetic code}& \text{(iv)}& \text{Unambiguous}\\ \text{(d)}& \text{Okazaki fragments}& \text{(ii)}& \text{DNA ligase}\end{array}$$
