Question

Why does recombination occur?

Answer 1

Recombination and its occurrence:

1. Recombinant DNA technology involves using enzymes and various laboratory techniques to manipulate and isolate DNA segments of interest.
2. This method can be used to combine (or splice) DNA from different species or to create genes with new functions.
3. So, basically, this process involves the introduction of a foreign piece of DNA structure into the genome which contains our gene of interest.
4. This gene which is introduced is the recombinant gene to create genes with new functions and variability and the technique is called the recombinant DNA technology.
5. DNA fragments are broken and recombined during the recombination process to create novel allele combinations.
6. The genetic variety that results from this process at the gene level reflects variations in the DNA sequences of various species.
7. Recombination occurs to ensure genetic diversity and to ensure the proper segregation of characters.
8. This process occurs during crossing over in meiosis.
9. It occurs to keep the characteristics and traits important for evolution intact.
10. It ensures that the offspring has different characteristics than the parents to ensure heredity and diversity.
