Answer: Sexual reproduction is advantageous over asexual reproduction because it reduces the rate of mutation accumulation.
New Zealand mud snails reproduce through asexual and sexual modes of reproduction. Asexual reproduction allows these organisms to reproduce more number of offsprings. Asexual reproduction advantageous as these organisms faces natural disaster conditions like tide, drought results in the decrease in the population. Therefore, does not get mate to undergo sexual reproduction. Sexual reproduction in these snails results in genetic variation in offsprings. Sexual reproduction results in increase in mutation rate in the genetic material being passed to offsprings because of resorting of genetic material being distributed from parent to offspring. This will result in genetic variations. Hence, parent will be different from offsprings. In asexual reproduction offsprings are the clones of parents as there is no resorting of genetic material takes place.
The enzyme complex that forms at the start of transcription is the Rna polymerase-promoter complex.
<h3>What is transcription?</h3>
Transcription is a biological process during which the information on DNA is transcribed into genetic codes in RNA.
The process of transcription occurs in 3 stages, which are:
- Initiation
- Elongation
- Termination
During initiation, an enzyme known as RNA polymerase binds to a region on the DNA to be transcribed. This region is known as the promoter region.
Thus, the binding leads to the formation of RNA polymerase-promoter complex, otherwise known as the initiation complex.
