G1 is followed by S phase (synthesis), during which DNA replication takes place. The completion of DNA synthesis is followed by the G2 phase (gap 2), during which cell growth continues and proteins are synthesized in preparation for mitosis.
Answer:
D. Lactic acid
Explanation:
Fermentation takes place When a molecule of glucose is broken down into pyruvate molecules. Fermentation is another source of gaining energy from cellular respiration.
During fermentation, electrons from electron transport chain combine with pyruvate molecules, and this reaction further proceeds in the presence of endogenous organic electron receptors. These organic electron receptors form waste products.
Common products synthesized during fermentation are lactic acid, lactose, and hydrogen. Lactic acid is formed when NADH transfers an electron to pyruvate molecule.
Answer:
A
Explanation:
1. All cells, prokaryotic as well as eukaryotic cells divided into two daughter cells by mitotic division. Before division, every cell must replicate their DNA, and makes two copies of their DNA, and finally divide into two daughter cells with equal number of chromosome.
2. Each daughter cell contain equal number of chromosome and same as the parental cell in case of chromosome number .
3. DNA replication occurs in the S phase( synthetic phase) of cell cycle.
