MCQ

$DNA$ fingerprinting refers to

✓
Molecular analysis of profiles of $DNA$ samples
B
Analysis of $DNA$ samples using imprinting device
C
Techniques used for molecular analysis of different specimens of $DNA$
D
Techniques used for identification of fingerprints of individuals

✓

Answer

Correct option: A.

Molecular analysis of profiles of $DNA$ samples

a
Important for $DNA$ fingerprinting are short nucleotide repeats that ary in number from person to person but are inherited. These are Variable Number Tandem Repeats or $VNTRs$ and these can be recognized only through molecular analysis of $DNA$ $SAMPLES$. Alec Jeffreys $(1985, 86)$ discovered this technique for the first time.
