Answer:
The correct answer is (d)modified guanine nucleotide.
Explanation:
When the transcription process is finished, the guanine cap is added to the 5' end of the RNAm so it can be recognized in the cytosol and not scrapped. On the other hand, a long strand of adenines or Poly A tail is also added but to the 3' end, for the same purpose.
Answer:
The answer is D.
Explanation:
The example given in the question is an example of gene flow which can be described as the movement of specific genes from the the gene pool population to population.
The act of catching the bigger fish and letting the smaller ones escape is changing the gene pool of the North East Arctic Cod and causing the next generations to have smaller and smaller sizes which is given as the genetic variation decrease due to gene flow.
I hope this answer helps.
The fatty acid sequence determines its shape because it helps shape them
Answer:
The action of the shifting continental plates of Earth has important effects on the course of speciation of living organisms by reproductively isolating populations or allowing previously separated populations to interbreed..
Explanation:
The formation of geological barriers such as mountains special cause of allopatric type, these barriers cause isolation which prevents two or more groups from mating each other regularly and finally there is speciation. On the other hand the movement of continental masses for example can cause the union of islands that allows a new genetic crossing between populations.
