The allele that can mask the presence of another allele is called dominant. The allele that is masked is recessive and if both alleles can be detected in the phenotype, then they are codominant. If they produce an intermediate phenotype like pink instead of red or white, then they have a relationship of incomplete dominance.
Answer:
GgRr
Explanation:
as it was stated in the question that one of the parent is a heterozygote for both alleles, It could only be written as GgRr. A cross between this parent and the double recessive parent would also give rise to the following listed genotypes, assuming the second Gr/gr in the question to be gr/gr. thus, we would have:
GgRr x ggrr
GR Gr gR gr
gr GR/gr Gr/gr gR/gr gr/gr
Answer:
The correct answer is The energy in the glucose is stored as kinetic energy in the ATP and released as potential energy when the molecule moves across the cell membrane.
Explanation:
Potential energy is required to move a molecule across the plasma membrane. This potential energy is derived from the hydrolysis of ATP in which(ATP) the energy is stored as kinetic energy.
ATP hydrolysis releases potential energy to drive the movement of molecule across the plasma membrane.
Answer:
If a DNA strand has 17% Thymine (T) the percentage of the other nitrogenous bases will be 33% of Guanine (G), 33% of Cytosine (C) and 17% of Adenine (A), according to Chargaff's law.
Explanation:
The percentage of nitrogenous bass in a DNA strand can be established by knowing the percentage of one of the bases present in the molecule, in this case knowing that Thymine corresponds to 17% of bases.
DNA has the nitrogenous bases adenine (A), guanine (G), thymine (T) and cytosine (C). The bases of one chain are matched with the bases of another, according to the complementarity of the nitrogenous bases, where:
- <em>Adenine is complemented with thymine A=T</em>
- <em>Guanine is complemented by cytosine G≡C</em>
According to this, DNA molecule there is as much T as A, and an equal amount of G and C, and the percentages of nitrogenous bases can be calculated according to Chargaff's rule.
Chargaff deduced that<u> in a DNA molecule the ratio of purine:pyrimidine is 1:1, so there must be the same amount of thymine as adenine and a similar amount of guanine for the cytosine</u>, according to the complementarity of the bases.
Calculating the percentages, according to the law of the base pair, if in a DNA chain there is 17% of T, in the molecule there is:
- <em>A = 17 %</em>
- <em>C = 33%</em>
- <em>T = 17%</em>
- <u><em>G = 33%</em></u>
- <em>Total ..... 100%</em>
