Explain what happens to the cell cycle if both p53 alleles are mutated.

Biology
1 answer:
elena55 [62]3 years ago
6 0
The p53 gene is a recessive tumor suppressor gene which functions as a key regulator for the cell cycle. In the event when only one p53 allele is mutated then the function of the p53 gene will persist and apoptosis (programmed cell death) will proceed if there are significant gene mutations in the cell. If two p53 alleles are mutated then the cell will not receive the signal to apoptose even with significant mutations and cancer will develop.

The neural pathway bringing temperature information from your left hand to the somatosensory cortex would have two synapses, wit
Westkost [7]

Answer:

The neural pathway bringing temperature information from your left hand to the somatosensory cortex would have two synapses, with the first being in the <u>spinal cord dorsal horn on the left side</u> and the second being in the <u>thalamus on the right side.</u>

Explanation:

The stimuli received by the external receptors must travel from the place where they are produced to the association centers located in the central nervous system, where the information is processed.

In the case of the sensory nerves, which conduct the temperature-related information from the left hand, it happens that:

  • They make their first synapse in the posterior horn of the spinal cord, responsible for receiving nerve impulses of sensitivity, on the same side as the stimulus (left).
  • The second synapse occurs in the thalamus, an organ of the central nervous system that is responsible for receiving information related to temperature. As the sensory and motor pathways are crossed, the portion of the thalamus that receives the information is the right one.

One of the consequences of the crossing of the sensory pathways is that everything related to one side of the body is processed on the opposite side of the somatosensory cortex.

Why is dna replication said to be semi-conservative
Neko [114]

During DNA Replication, the DNA molecule unzips itself so that there are two free strands of DNA. Both of those strands then create new complementary strands of DNA. Thus every subsequent generation of DNA uses one of the parent cell's strand of DNA as a template, which is why DNA replication is said to be semi-conservative. Hope this helped!

What specifically is this biochemical used for, and how is it broken down during digestion?
Cerrena [4.2K]
Digestion occurs in the stomach and the duodenum through the action of three main enzymes: pepsin, secreted by the stomach, and trypsin and chymotrypsin, secreted by the pancreas.During carbohydrate digestion the bonds between glucose molecules are broken by salivary and pancreatic amylase.The digestion of certain fats begins in the mouth, where short-chain lipids break down into diglycerides because of lingual lipase. The fat present in the small intestine stimulates the release of lipase from the pancreas, and bile from the liver enables the breakdown of fats into fatty acids.DNA and RNA are broken down into mononucleotides by the nucleases deoxyribonuclease and ribonuclease (DNase and RNase) that are released by the pancreas.

What effect does plate tectonics have an organic evolution
Agata [3.3K]

Plate tectonics have the potential to affect organic evolution due to the fact that the movement of these plates may well cause land masses to shift and cause a change in climate as a result
