If each cell has multiple mutations, why do most of us have normally-functioning tissues and organs?

Biology
1 answer:
attashe74 [19]3 years ago
7 0

Most of us has normally-functioning tissue and organs even if the cell has multiple mutations because of DNA repair mechanism.This repair mechanism has multiple processes by which any damage in the genetic material can be repaired before the protein is synthesized.In human beings there are many factors like environmental factors and metabolic activities that can cause mutation in DNA but the repair system does not allows the abnormal DNA to form abnormal proteins this saves the abnormal functioning of tissues and organs .More than 1 million molecular lesions per cell are repaired, these lesions leads to structural damage and the damaged cells are killed by apoptosis. This repair system continues as the cells divide and any alteration in the DNA is solved prior to the protein synthesis this result sin normal functioning of tissues and organs.

Embryonic tissues develop during the _________ stage.
Hitman42 [59]
<span>Embryonic tissues or germ layers develop during the gastrulation stage.</span> <span>Gastrulation is a process in embryonic development during which the single-layered blastula is reorganized into a three-layered(or two-layered) structure called the gastrula. <span>Two primary germ layers(embryonic tissues) are an inner layer-endoderm and an outer layer-ectoderm. Endoderm and ectoderm interact and produce a third layer-mesoderm. Gastrulation is followed by organogenesis, three germ layers will give rise to specific tissue and organ.For example, ectoderm gives rise to epidermis and nervous system, endoderm to the digestive system and mesoderm to muscles, bones…</span></span>

What ion movement changes the membrane potential in a contractile cell from negative to positive during the rapid depolarization
Lesechka [4]

Answer:

The influx of calcium ions.

Explanation:

The influx of calcium ions at a certain point produces phase of the action potential also called depolarization which results in the ion movement changes the membrane potential from negative to positive inside the cell.

In action potential, calcium ions may control gene transcription, cell excitability, and neurotransmitter release. In chemical synapses, the influx of calcium ions leads to vesicles filled with neurotransmitters move to the surface of the cell, and into the synaptic cleft release their contents.
