Which very important process must occur prior to cell division and why?
question 4 options:

protein synthesis must occur prior to cell division in order for cells to grow properly.

dna replication must occur prior to cell division because t bases should not be created in new cells.

dna replication must occur prior to cell division because dna carries the coding or instructions for all cell function.

transcription must occur prior to cell division because rna needs to be able to leave the nucleus for cells to divide.

videntify the dna change shown in the diagram and explain how that change can result in the increased genetic diversity often seen among siblings.identify the dna change shown in the diagram and explain how that change can result in the increased genetic diversity often seen among siblings.

your answer is "the 1950's"

an organism's phenotype is the  form of a trait  that it  displays. for  flowercolor, a pea  plant  can  display  a phenotype of purple or white flowers. an organism's  genotype  is the alleles of a gene it contains. based on his data, mendel concluded that a phenotype can be  determined  by more than one  genotype.

there are so many examples for that in different areas, like biology experiment carried out in our lab recently.
