The distribution of related animals and plants across the world shows that those organisms have common ancestor.
There is a term in biology- the most recent common ancestor (MRCA) and it is the most recent individual from which all the organisms are directly descended. It is hard for scientist to identify the exact MRCA, but it is estimated the time at which the MRCA lived (3.5 to 3.8 billion years ago). It is called Last Universal Common Ancestor (LUCA).
Answer:
100 000
Explanation:
The average length of a base pair (bp) is 340 pm [340 × 10^(-12) m]
Length of DNA = No. of bp × length of bp
34 × 10^-6 m = n × 340 × 10^-12 m
n = (34 × 10^-6)/(340 × 10^-12) = 100 000
The DNA molecule contains 100 000 base pairs.
