Discussion

20314.	Question : Assertion: Both the strands of DNA can be copied during transcription. Reason: This will help to produce more RNA with differentsequences.
Answer» Solution :Both the strands of DNA are not copied during transcription for two reasons. 1. If both the strands ACT as a template, they would code for RNA with different sequences. This in turn would code for proteins with different amino acid sequences. This would result in one SEGMENT of DNA coding for two different proteins, hence complicate the genetic INFORMATION transfer MACHINERY. 2. If two RNAmolecules were produced simultaneously, double stranded RNA complementary to each other would be FORMED. This would prevent RNA from being translated into proteins.

Discussion

20320.	Question :Both meiosis (gametogenesis) and fertilization are essential to maintain chromosome number constant. Why?
Answer» Solution : Meiosis occurs in gametogenesis and transforms diploid gametogonia into haploid gametes, while fertilization involves fusion of gametes and restores the diploidy. If there is no meiosis during gametogenesis, then the gametes will be diploid and individual PRODUCED will be TETRAPLOID (4N), but when gametis meiosis is not followed by fertilization then the individual formed will be haploid (N). So meiosis and fertilization are two important processes INVOLVED in sexual reproduction which collectively maintain the chromosome number CONSTANT from generation to generation.
