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:
The correct option is A. A directory of relatives' phone numbers
Explanation:
Family communication plan is a measure taken to contact the relatives of a person if an emergency situation arises for a person. In today's modern world, emergencies can happen at any time so it is very important to have a family communication plan so that the relatives of a person be informed immediately. Hence, option A is correct.
Other options are false because none of the other options will be usable in case of an emergency.
B
A convergent boundary is an earth where two or more lithospheric plates collide
