Here you have two characteristics to cross on Punnet square: Blood type and pigment.
They told you both parents are AB this means co-dominance of A and B, you draw the Punnett square (photo), and you'll see your offspring possibilities are 50% AB type, 25% A type, and 25% B type.
Now they told you both parents are homozygous for pigments this means Aa. When you draw the Punnett square (photo), you'll see your offspring possibilities are 50% Aa, 25% AA, and 25% aa.
75% pigmented and 25% albino.
Question: Please use the following information to answer the question(s) below. A group of six students has taken samples of their own cheek cells, purified the DNA, and used a restriction enzyme known to cut at zero, one, or two sites in a particular gene of interest.
Analysis of the data obtained shows that two students each have two fragments, two students each have three fragments, and two students each have one only. What does this demonstrate?
Answer:
"The two students who have two fragments have one restriction site in this region."
Explanation:
A restriction enzyme, restriction endonuclease, or restrictase is an enzyme that cuts DNA into trashes at or close precise appreciation sites inside particles identified as restriction locations. Restriction enzymes are one session of the wider endonuclease collection of enzymes. In the laboratory, restriction enzymes (or restriction endonucleases) are used to cut DNA into minor trashes. The scratches are constantly made at exact nucleotide arrangements. Unlike restriction enzymes recognise and cut diverse DNA sequences.
Answer:
A) photorespiration.
Explanation:
Photorespiration is the harmful metabolic process which takes place when the concentration of oxygen in the leaf increases compared to carbon dioxide.
The RUBISCO enzyme which usually binds the carbon dioxide now binds the oxygen and form the phosphoglycolate and 3 phosphoglycerate.
The phosphoglycolate is lost through the Calvin cycle as Carbon dioxide molecule. This loss proves harmful to the plants.
The photorespiration occurs when the plant faces high temperature therefore n order to prevent water loss the stomata gets closed. This result in the binding of the oxygen to the RUBISCO and thus photorespiration begins.
Thus, Option-A is correct.
