Question

if there are 3.3*10^9 bp present in genome then what would be length of dna

Answer 1

Answer:

2.2 metres

Explanation:

If there are 3.3*10⁹ bp present in genome then what would be the length of the dna of any somatic cell

total bp present in a genome = 3.3*10⁹ bp

total bp present in a somatic cell = 6.6*10⁹ bp

NOTE — in the question somatic cells refers to the somatic cells of mammalian/humans. therefore the bp present in a somatic cell will be doubled cuz humans are diploid, so the genome will be doubled.

distance between two consecutive bp = 0.34 nm = 0.34*10-9 m (to be learnt)

length of dna = total number of bp × distance between two consecutive bp

= 6.6*10^9 × 0.34*10^-9

= 2.2 metres
