Answer:
Explanation:
Mendel's law of independent assortment state that two different genes assort independently in gamete formation.
To reach this conclusion, one has to do a dihybrid cross. This means that two genes responsible for different traits need to be analyzed at the same time.
1) Starting with a <u>parental generation of a cross between two pure lines</u> (homozygous for both genes) <u>with different traits</u>, a plant with yellow and round seeds (YYRR) and another with green and wrinkled seeds (yyrr). <u>The F1 will be phenotypically homogeneous (</u>yellow and round)<u>, and genotypically heterozygous (</u><u>YyRr</u><u>)</u>.
2) If the individuals from the F1 are crossed with one another, we have to do a Punnett Square to determine the phenotypic ratio of the F2.
- If the genes assort independently, the F1 individuals will produce their different gametes with the same probability. Each possible gamete will appear in a 1/4 proportion: YR, Yr, yR, yr.
- The 9:3:3:1 ratio is a result of analyzing the possible phenotypes that result from the dihybrid cross.
See the attached image for an illustration of the crosses in each generation and the Punnett Square.
Active site
A reactant
binds to an enzyme in a region known as the active site during a reaction. The active site is the
most important part of the enzyme because it is where the chemical reaction
happens. It usually contains three to four amino acids and a binding site that
binds the substrate and prepares it for catalysis.
Answer:
Explanation:
Glycolysis is an anaerobic process - it does not need oxygen to proceed. ... They follow glycolysis with the Krebs cycle and electron transport to make more ATP than by glycolysis alone. Cellular respiration that proceeds in the presence of oxygen is called aerobic respiration.
