There are two major classes of actin-nucleating proteins:

I- Formins

II- Arp2/3 complex

a) nucleates the assembly of branched actin networks

b) landing site for profilin–ATP–G-actin

Choose the correct statement

a.The 30-nm fiber is further folded, results in 10000-fold compaction in euchromatin in interphase chromatin and in mitotic chromosomes to achieve an overall 10,00- fold compaction in euchromatin.

b.This 30-nm fiber is further folded, results in 1000-fold compaction in euchromatin in interphase chromatin and in mitotic chromosomes to achieve an overall 10,000- fold compaction in euchromatin.

c.Heterochromatin generally maintains 10,000-fold compaction in both interphase and mitosis after 30 nm.

d.Heterochromatin generally maintains 10,00-fold compaction in interphase and 10,000 folds in  mitosis after 30 nm.

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