Answer:
362 nucleosomes
Explanation:
A nucleosome repeat is made up of the DNA (146 bp) wrapped around the core nucleosome particle and the linker DNA (110 bp as in this situation). We can conclude that, every repeat stands for 256 (146 + 110) base pairs of DNA.
We are given the length of the entire region to be 92,672 bp long,
To determine the number of nucleosomes to organize the region into the 10nm fiber structure
Let,
Number of nucleosomes =
the length of the entire region
------------------- -----
base pairs of DNA.
= 92,672
-------
256
= 362 nucleosomes
Therefore, 362 nucleosomes is needed to structure the region into the 10nm fiber structure.
Answer:
girl.... I don't even know what to say
Answer:
The given statement is true
Explanation:
Ultimately, it is the environment which influences natural selection and thus the evolution of populations. Is it true or false
Solution
It is true that environment influences the natural selection which is mainly governed by the presence of useful resources that can support an individual. Natural selection leads to emergence of useful trait that can help an individual in adopting traits that can make him/her fit thereby causing evolution of species.
Hence, the given statement is true
ATP<span> is responsible for cocking (pulling back) the myosin head, ready for another cycle. When it binds to the myosin head, it causes the cross bridge between actin and myosin to detach. </span>ATP<span> then provides the energy to pull the myosin back.</span>
The endomembrane system has the different membranes that are suspended in the cytoplasm within a eukaryotic cell. The membranes divide the cell into functional and structural compartments, or organelles.
