Answer:
(A) True
Explanation:
Vitamins are important for the human body because it plays an important function in the body like in metabolism, calcium absorption, releasing energy from food, cell damage repair, etc.
For example, vitamin D can be made by the body itself. This vitamin is made by the skin when UV radiation from the sun falls on the skin. This vitamin act as membrane antioxidant and helps in inhibiting iron-dependent lipid peroxidation in cell's liposomes.
It also helps in calcium regulation in the body and without vitamin D the dietary calcium is not properly absorbed.
In diseases, similar patterns of mutations in harmless genes may possibly be a cause or an effect of the disease. To investigate if it is a cause, it is worth looking into the proteins synthesized by the gene and whether it’s structure or functionality is affected by the pattern observed. It is also worth looking into the downstream effects possibly caused by the pattern in the gene. The gene may encode a non coding region which could affect post transcriptional splicing for example.
Answer:
the answer is A before cell division (mitosis or meiosis)
Explanation:
The S phase of a cell cycle occurs during interphase, before mitosis or meiosis, and is responsible for the synthesis or replication of DNA. In this way, the genetic material of a cell is doubled before it enters mitosis or meiosis, allowing there to be enough DNA to be split into daughter cells.
