Answer:

1.7 x 107 nucleosomes.

Explanation:

The number of nucleosomes can be calculated by the following formula:

Nucleosomes = Genome size/ total number of base pairs.

Here, the genome size is 3.4×109.

Total number of base pair = number of base pairs in nucleosome core particle + linker DNA.

Total number of base pair = 146 + 50 = 196.

Number of nucleosome = 3.4×109 / 196.

Number of nucleosome = 1.7 x 107 nucleosomes.

Thus, the answer is 1.7 x 107 nucleosomes.

"Tryptophan self-controls its synthesis." Justify this statement.
miskamm [114]
Just say we have a big amount of tryptophan in the sense that it exceeds, tryptophan would act as a co-repressor which prevents synthesis of more enzymes for its production

Hope this helps :)

What is the relationship between convection currents, seafloor spreading, and the formation of ocean basins?
beks73 [17]

Seafloor spreading occurs at divergent plate boundaries. As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense. The less-dense material rises, often forming a mountain or elevated area of the seafloor.
