A deamination occurs on the cytosine residue in the following DNA sequence. This cytosine residue happens to be methylated on th

e 5-position of the aromatic ring.
5'-GAATCG-3'
(Note: the top strand is shown; this is the strand where the deamination occurs.) If the mutation is not repaired, and a round of DNA replication occurs, then the sequence of the newly-replicated complementary strand (i.e., the bottom strand) will be:
A. 5-CAATTC-3'
B. 5'-CGATTC-3
C. 5'-GAATCG-3
D. 5'-GAATTC-3
E. None of the above

Answer:

A. 5-CAATTC-3'

Explanation:

Due to the spontaneous mutation of the cytosine, becoming uracil, the change in the new complementary strand would occur as follows:

5'-GAATCG-3 '-> Cytosine deamination = 5'-GAATUG-3' -> the new replicated complement is = 5-CAATTC-3 '

Remembering that Uracil equals a thymine in DNA, for that reason the mutated uracil base becomes Adenine when its synthesized in the new strand

Explanation:

The cultural tradition of using stones to crack nuts has arisen in only some populations of the Chimpanzees who live in environments containing oil palm nuts, meaning not all Chimpanzees actually use stone to crack down the nut except few of them and this because their environment contain oil palm nuts.

The liver acts to keep blood glucose at a relatively constant level. It takes up glucose from the blood when levels are too high
postnew [5]
Yes, these actions are an example of homeostasis. To fully understand this question you need to know the basic concept of homeostasis. Homeostasis is the body's regulation. What do I mean by that? It's simple, when you have a fever your body's temperature can skyrocket to 100 or more, when you start to sweat or get the chills that's your body's way to cool you down and fight the infection. Another example; when you do any physical activity, you sweat from it depending on the intensity. If you didn't sweat you would probably overheat and that would lead to other complications. Basically when you do exercise you sweat because your body is warm and that's the homeostasis mechanism that helps cool down your body bring it to it's normal temperature. So in end answering your question in more detail by the liver regulating the body by taking glucose in when levels are too high or adding glucose in when levels are too low is an example of homeostasis because the body is regulating itself to come back to it's normal healthy function state.

Hope this helped :)
