Question

Which enzyme is required in the Pachytene stage of meiosis for recombination to occur?

Answer 1

Hint: The recombinases are the enzymes with genetic recombination and are used in the multicellular organism for the manipulation of the structure of genomes and to control gene expression.

Complete answer:
The enzyme recombinase is required in the Pachytene stage of meiosis. When a fully formed synaptonemal complex exists is defined as the Pachytene stage during which the homologous organs chromosomes get thickened and become recombinant. The chromosomal crossing over is important for the accurate segregation of the chiasmata which holds the maternal and paternal chromosomes together. In meiosis, the daughter cells are not similar to that of a parent because of crossing over in which the cells are different from parents cells because of the process of crossing over which occurs between homologous chromosomes and chromosomal segments which are exchanged between homologous chromosomes during the process of crossing over which is the main cause of variations.
The swapping of genetic material that occurs in the germline is the crossing over which forms during the formation of egg and sperm cells which are known as meiosis and the paired chromosome from each parent gets aligned so that the similar DNA sequences from the paired chromosomes get to cross over one another. The shuffling of genetic material is the result of crossing over which is an important cause of genetic variation that is seen among offsprings. The paired chromosomes or homologs are lined up during losses on the meiotic plates and are known as paired chromosomes when they have the biological mechanism that sort of keeps them together. The chiasmata keep the strands of the duplicated homologous chromosomes which break and recombine with the same strand of another homolog.

So, the answer to this question is 'Recombinase'.

Note:
The process of meiosis is divided into 9 stages which are divided between the first time when the cell divides which is the meiosis l and the second time when it provides which is known as the meiosis II. The chromosome is composed of two sister chromatids that contain identical genetic information and one cell divides to form four daughter cells during meiosis.
