If a p53 gene is defective it may cause cell cycle to stop functioning normally. Without this cell cycle check, cells will divide continuosly creating many chromosomal damage.
Answer:
A cap is added to the 5 end of the mRNA
Explanation:
In prokaryotes, the translation process takes place simultaneously with the transcription but the mRNA molecule after synthesis undergoes some post-translation modification which protects the mRNA from the cytosolic environment.
One of these modifications is known as capping which refers to the addition of the cap at 5' end of the mRNA. This cap is added by an enzyme called guanyl transferease and protects the end of the mRNA.
Thus, the selected option is correct.
Chemical potential energy. Potential energy being converted into kinetic energy. A lump of coal and a can of gasoline
Darwins observations about the fossils support his theory of the tree of life which states we all derive from the same one spark of life. so when he found the fossils in the mountain and it closely resembled animals he had seen on his voyages so this made his hypothesis more believable.
I think this happens when there is no gene flow or when the population is small. Small population, germ line mutation, beneficial mutation that gets into many progeny and is of high chance of luck. Genetic drift involves a process in which allele frequencies within a population change by chance only, as a result of sampling error from generation to generation. Genetic drift occurs mostly in small population since the infrequently occurring alleles face a greater chance of being lost.
