How many MTP are performed in a year all over the world :
1 4.5 to 5 million
2 450 to 500 million
3 4 to 5 million
4 45 to 50 million
Explanation:
d
Intentional or voluntary termination of pregnancy
before full term is called medical termination of pregnancy (MTP) or induced abortion. Nearly 45 to 50
million MTPs are performed in a year all over the
world which accounts to 1/5th of the total number
of conceived pregnancies in a year.

If a sample of B-DNA containes 100000 Nucleosome then what is the length of B-DNA sample :
1 0.68 mm
2 6.8 mm
3 0.68 cm
4 Both 2 and 3
Explanation:
d
One nucleosome = 200 bp
Hence total bp = 200 × 100000
Distance between two bp = 3.4 × 10–10 metre
The length of B-DNA sample = 3.4 × 10–10 × 2 ×
107
= 6.8 × 10–3
= 6.8 mm = 0.68 cm
