Answer:
an enzyme substrate is the material upon which an enzyme acts.
Explanation:
The correct option is A ie the process whereby non-sister chromatids exchange genetic material
- Between prophase I and metaphase I, a process known as crossing over occurs in which two homologous non-sister chromatids join up and exchange various pieces of genetic material to create two recombinant chromosome sister chromatids.
- When genetic material is switched between two chromosomes, this process is known as crossing over.
- It is in charge of causing genetic variation among members of a species.
- Only the reproductive cells known as gametes undergo this process.
- The steps involved in crossing over are as follows:
1) Synapsis.
2) Chromosome duplication
3) Crossing over.
4) Terminalizataion.
