"By recombination, we mean the process by which two molecules or DNA exchange places with each other.
Recombinant DNA is made in prophase 1, by a process known as crossing over where homologous DNA pairs line up and exchange segments with each other in a process known as passing over.
A process involving a reduction in the quantity of genetic material is termed as Meiosis, which is a type of cell division. It occurs in two phases, namely – meiosis I and meiosis II.
In the pachytene event of prophase I, chromosomes cross-over wherein the exchange of segments between non-sister chromatids of homologous chromosomes occurs. This leads to the formation of recombinant DNA in the process of meiosis.
➖Meiosis is a process that involves the reduction in the amount of genetic material.
➖It is two types, namely meiosis I and meiosis II.
➖During the pachytene stage of prophase I, crossing over of chromosomes takes place where the exchange of segments between non-sister chromatids of homlogous chromosomes takes place.
➖This results in the formation of recombinant DNA.
botanical gardens are very important. because it conserves plant rare species. and plant have very very importance in our life.
in botanical gardens plant are classified and take good care of plants and their habits also.
botanical gardens are source of study for biology
