Finding: The overall degree of divergence between two homologous exons in related genes corresponds to the differences between the polypeptides.

Reason: Overall degree of divergence between two homologous exons is mostly a result of base substitutions.

Choose the correct option 

a. Individual nucleosomes can be obtained by treating chromatin with the endonuclease micrococcal nuclease (MNase), which cuts the DNA between nucleosomes, a region known as H2A-H2B dimer region. 

b. Individual nucleosomes can be obtained by treating chromatin with the endonuclease micrococcal nuclease (MNase), which cuts the DNA between nucleosomes, a region known as linker DNA.

c. Mononucleosomes typically have 200 bp DNA. End-trimming reduces the length of DNA first to 165 bp and then generates core particles with 146 bp.

d. Mononucleosomes typically have 200 bp DNA. End-trimming reduces the length of DNA first to 165 bp and then generates core particles with 200 bp.
