The altered protein affected the function of the cell membrane. The cell membrane which contain a bilayer control the movement of substance in and out of the cell and organelles. Due to this it is selective permeable to ion and organic molecules.
Answer:
2.Less than 73% of the populations would have only one allele present.
Explanation:
The two alleles chosen do not affect the fitness of flies in the lab environment, so Kerr and Wright could be confident that if changes in the frequency of normal and forked phenotypes occurred, they would not be due to natural selection.
Using a larger breeding population would not be expected to alter the outcome of the experiment.
Answer:
In the presence of oxygen, respiration of yeast produces carbon dioxide and water. In the absence of oxygen, respiration of yeast produces carbon dioxide and alcohol.
Under the assumption that the yeast has insufficient exposure to oxygen in the surrounding air in the testtube, alcohol and carbon dioxide would be expected to be found in the test tube
The correct answer is C
<span>Erwin Chargaff's research found that there are two pairs of nucleotides in the DNA molecule, adenine-thymine, and guanine-cytosine.
Those two pairs of nucleotides are complementary and since they pair up in the DNA molecule, the amount of one nucleotide in the pair must be equal to the amount of the other nucleotide of the pair.
He also found that different species have different proportions of nucleotides, which proved that DNA is the carrier of genetic information, not the proteins.</span>
