Non-disjunction occurs when a the chromosomes do not split properly during meiosis resulting in too few chromosomes I believe.
An independent variable is a variable which change is not affected by that of another variable. By process of elimination you can take out B and C. An independent variable can also change so that takes out A. That leaves D.
Just as stated and also explained, the correct answer is <span>a long chain of adenine nucleotides is added to the 3' end of mRNA during terminationof transcription. That is the only statement that is true about the polyadenylation mechanism. Hope this is helpful</span>
Binary fission is a type of asexual reproduction. This is when the cell divides into halves. So 1 cell would end up as 2 smaller cells.
