Crossing over increases genetic variation because due to this, each of the homologous chromosomes get a new combination of traits/ genes and since a each cell has different homologous chromosomes, genetic variotion will occur
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.
