28. Molecular Basis

Question 1

The process of translation of mRNA to protein begins as soon as

Answer 1

Small subunit of ribosome encounters mRNA

Question 2

The number of nitrogen bases in 6.8nm long dna fragment
1) 20
2) 40
3) 10
4) 30

Answer 2

Length of dna = total no of base pairs × distance between two consecutive bp
So we get total no of base pairs as 20
20 × 2 = 40 total bases 🤭
