Answer:
The cell cycle of cell multiplication is regulated by three types of genes, the regulatory genes that control mutations, the generic promoters of cell replication, and genes that inhibit cell replication.
The balance between these three types of gene group are what result in a good multiplication of cells without mutations or neoplastic developments.
The p53 gene is one of the genes that is considered as the guardians of the genome, since it is in charge of corroborating and regulating mutated cells, in this way it inhibits their progression in the cell cycle by putting a stop to not replicate defective genes or genes with alterations.
Explanation:
The p53 gene is one of the most altered genes seen in malignant neoplasms, since by altering our guardian of the genome many mutations overlook and more carcinogenic potential will have neoplastic tissue.
In the three groups of genes that we write, all three have a fundamental roll in the cell cycle, but in order to trigger malignant neoplasms, it is necessary that there be a continuous series of gene mutations in these three groups, it is not enough with the mutation of a single gen.
Answer:
Birth control pills are a synthetic form of the hormones progesterone and estrogen. They prevent ovulation by maintaining more consistent hormone levels. Without a peak in estrogen, the ovary doesn't get the signal to release an egg.
Explanation:
Answer:
If the two mutations are on different genes, mating together, the progeny will have the function restored.else if the mutation is the same, the function shall remain and wingless progeny will be visible.
Explanation:Just to explain shall use an example.Suppose there are two different mutations . The genes be called as 1 and 2.Also assume that they make proteins 1 and 2.Now the two proteins shall perform two different functions but the end wingless character is maintained.Now suppose fly 1 has mutation 1 and protein 1 is not being synthesized .But yet it is being synthesized in fly 2, that has a mutation in protein 2.when the two are mated protein 1 comes from fly 2 and protein 2 comes from Fly 1, as a result the two proteins and their functional copies are available and hence all functions completed and the fly develops a wing.The essential thing to understand is that if two flies have two different mutations both will have the two proteins from the other fly and the function of the protein will be completed.
