Question

Identify A and B in the given table.

$\begin{array}{cc}\text{Technique}& \text{Usage}\\ \text{DNA cleaving}& \text{used for cutting genes at special sites}\\ \text{(A) \_\_\_\_\_\_\_\_\_}& \text{used for testing the arrangement of nucleotide}\\ \text{Gene therapy}& \text{used for treating genetic diseases}\\ \text{(B) \_\_\_\_\_\_\_\_\_}& \text{used for locating the position of a gene}\end{array}$

• A. A - Gene mapping, B - DNA profiling
• B. A - DNA profiling, B - Gene mapping
• C. A - Ligase, B - Gene mapping
• D. A - DNA profiling, B - Ligase

Answer 1

The correct option is B A - DNA profiling, B - Gene mapping

There are several techniques in genetic engineering that are used for variety of purposes.
(1) DNA cleaving - a process that makes use of restriction enzymes to cut up DNA at certain special sites known as the restriction sites.
(2) DNA profiling - a process used to test the arrangement of nucleotides of a given sample of DNA. It's useful for finding lost child of a parent.
(3) Gene therapy - a technique that is used to treat several genetic disorders such as haemophilia.
(4) Gene mapping - a technique used to locate the position of a particular gene in DNA
