A chromosome (chromo- + -some) is a packaged and organized structure containing most of the DNA of a living organism. It is not usually found on its own, but rather is structured by being wrapped around protein complexes called nucleosomes, which consist of proteins called histones.

Which is the role of restriction enzymes?
dezoksy [38]
Restriction enzymes and or restriction endonucleases are involved at recognizing specific sequence of nucleotides and cutting or splicing them at appropriate regions to produce fragments that can either be sticky ends or blunt ends depending on where they cut and the nature of nucleotides involved within the fragments. They play an important role in genetic engineering, as geneticists can use them for placing into extra chromosomal information and or content of plasmids in certain bacteria, from other sources, for instance antibiotics, grow and or produce many individual colonies of bacteria, isolate them and one would have many sequences for instance that can code for an antibiotic that can be extracted and used further. Assuming the bacteria's plasmid can take in that sequence.

Suppose the volume of milk in a glass is 230 cubic cm. If 1 gallon of milk equals 3.79 liters, there are how many glasses of mil
balu736 [363]
Volume of milk that a glass can hold = 230 cubic cm
It is already given that
1 gallon of milk = 3.79 liters
W already know
1 liter = 1000 cubic cm
Then
3.79 liters = 1000 * 3.79 cubic cm
                = 3790 cubic cm
Now
Number of glasses needed to contain 230 cm^3 of milk = 1
So
<span>Number of glasses needed to contain 3790 cm^3 of milk = 3790/230
</span>                                                                                           = 16.48
From the above deduction, we can conclude that 17 glasses of milk are required to hold 1 gallon of milk.

Explanation:

Explanation:

<em>Complete answer: </em>

<em>a. foot tapping rhythm </em>

<em>b. long-term memory </em>

<em>c. breath holding </em>

<em>d. circadian rhythm </em>

The cerebral cortex plays a major role in all of the following except d. circadian rhythm

The cerebrum is split into the left and right hemispheres, while the cerebral cortex makes up the outer layer of the brain and is comprised of gray matter. Gray matter is made up of unmyelinated neurons.

The cerebral cortex is described as having motor, sensory and association areas, and is involved in thought, memory, perception, awareness, and language. Overall, it is associated with voluntary movement, thus the circadian rhythm, involved in homeostasis and the autonomic nervous system, is unrelated to its function.
