Hello your question is incomplete attached below is the complete question
answer : = 1.25
Explanation:
i) Determine the rate of mtDNA percent divergence
From the data given the most closely related specie is Chimpanzee ( 8.8 sequence difference )
Note : Given that this divergence took place seven million years from now
∴The rate of mtDNA percent divergence per 1 millions years
= 8.8 / 7 = 1.25
Answer:
Mutation. Mutations are changes to an organism's DNA and are an important driver of diversity in populations. Species evolve because of the accumulation of mutations that occur over time. ... Some mutations are unfavorable or harmful and are quickly eliminated from the population by natural selection.
Answer:
a) snRNA
Explanation:
The association of small nuclear RNA (snRNA) and some specific proteins forms small nuclear ribonucleoprotein complexes. Some complexes are spliceosomes, molecular machines -made up of a snRNA and about 80 proteins- that remove introns from pre-mRNAs via successive phosphoryl transfer reactions.
One advantage of genetic engineering is the production of valuable proteins: recombinant DNA made possible the use of bacteria to produce proteins of medical importance such as genetically engineered human insulin which is of great importance.
Another advantage is the production of vaccines. Vaccines produced by genetic engineering offer an advantage that the microbial strains from which proteins are extracted do not contain complete viruses and thus there is no risk of accidental inoculation with live virus.
