Cyclins and cyclin-dependent kinases are responsible for the progress of the cell through the various checkpoints.
Answer:
B. 100 percent white
Explanation:
According to Mendel's law of dominance, the dominant allele of a gene masks the expression of the recessive allele in a heterozygous state. Therefore, when two pure breeding plants that differ with respect to one genetic trait are crossed, the progeny expresses only the dominant phenotype. Here, one allele should be completely dominant over the other. The allele for the white flowers is completely dominant over the allele for the blue flowers.
Let' assume that the allele "W" imparts white color to the flowers while the allele "w" gives blue color. When a true-breeding blue-flowered plant (ww) is crossed with a true-breeding white-flowered plant (WW), the progeny would be heterozygous for the dominant allele "W" and would exhibit "white color of flowers" (the dominant trait).
WW (white-flowered plant) x ww (blue-flowered plant) = Ww (white-flowered plant)
Answer:
C. This is an example of VNTRs.
Explanation:
VNTRs are Variable Number Tandem Repeats. These are short sequences of DNA repeated in tandem (that is, the sequences are repeated one next to the other) a certain number of times. Unrelated individuals have a different number of repetitions for a certain region of the DNA, therefore the total length of the fragment is variable among individuals, depending on how many times the short sequence is repeated.
If the statement is asking whether it is true or false, the
answer is true. The body can make its own lipid because of the food that we eat
and also because it is found in the body where it is located in the tissues and
the cells. It does compose of ring structure as it has multiple rings which are
considered essential and the lipids are considered to be a part of a cell
membrane.
