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

Biology

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.

Describe the function of each of the following in protein synthesis; rRNA, mRNA, and tRNA
Drupady [299]
Proteins synthesis requires transcription of DNA (containing information) to mRNA then this goes out of the cell’s nucleus to cytoplasm; and translation of mRNA together with ribosome and tRNA to synthesize proteins. Further steps are the following: 1) One side of DNA strand is copied to become mRNA (messenger RNA). 2) mRNA goes out the cell’s nucleus, next to cytoplasm and then to ribosome. 3) mRNA works with ribosome’s 3 bases at the same time. 4) tRNA (transfer RNA) connects with available DNA bases. <span>5) tRNA releases the amino acids which in turn combines with the other produced amino acid chains from different DNAs. </span>
