The human genome consists of approximately 3 billion base pairs. If humans typically differ from one another by about 3 million base pairs, what is the nucleotide variability of Homo sapiens?
How was this calculated?
Homework Answers
Given information,
Human genome size = 3 X 10^9 bp
Humans typically differ from one another by about 3 million base
pairs
Nucleotide variability is measured by comparing the sequences of
different individuals.
Nucleotide variability = (Number of differences/Genome size) X
100
= [3 X 10^6 X 100](3 X 10^9)
= 0.1%
It indicates that human species is relatively young species.

1. The genome of organism A consists of approximately 2.184 ×109 base pairs, and DNA synthesis occurs at a rate of 500 base pairs per second. How many minutes would it take to synthesize the entire genome of organism A, if there were only one origin of replication? 2. It turns out that organism A is actually able to synthesize its entire 2.184 ×109 bp genome in only 35 minutes. How many origins of replication must there be? 3. The...

One copy of the human genome is 3 billion (3 X 109base pairs). Pretend that instead of 4 bases (AGCT) there are 5, and that the 5th base (called D) pairs with itself. Pretend also that all 5 bases are present at equal frequency in the human genome. Suppose you digested to completion one copy of the human genome with the enzyme Eco RI (recognition sequence 5'-GAATTC). A Given the information above about the 5thbase, what would be the average...
