Question

Assuming human genome as 3× 10^9 bp in how many base sequence would there be difference

Answer 1

Human genome is said to be approximately 3 x 109 bp. The sequences of the 3 billion chemical base pairs that make up human DNA were determined in human genome project. Although differences in base sequences can be measured by the mutation rate, which measures various types of mutations that occurred.

Answer 2

Hello Dear,

# Given question has these options -

(1) 3×10^4

(2) 3×10^5

(3) 3×10^6

(4) 10^6

● Answer -

(3) 3×10^6

◆ Explanation -

According to the research by Human Genome Project, 99.9 % genome of all the humans is exactly similar.

Now, variation in genome = 100 - 99.9 = 0.1 %

Difference in base pairs will be calculated as -

Difference in base pairs = variation in genome × base pairs in genome

Difference in base pairs = 0.1% × 3×10^9

Difference in base pairs = 0.1/100 × 3×10^8

Difference in base pairs = 3×10^6 bp

Therefore, there is difference of 3×10^6 bp in base sequence of humans.

Hope this helps you.
