During metaphase 1 of meiosis of the cell cycle chromosomal translocation occur.

Explanation:

Chromosomal translocation is abnormal phenomenon when a fragment of chromosomes detaches and gets stick to the non-homologous chromosome in an individual. These are causative of aneuploid, cancer and infertility in organism.

In metaphase 1 of meiosis the chromosomes gets aligned on the metaphase plate. This leads to surety of equal number of chromosome in the cell.

Chromosomal translocation are seen in metaphase 1 because it is the phase of rearrangement of chromosomes where fragments easily gets attach to the other chromosome.

DNA - Option C.

Gene - Option A.

Chromosomes - Option B.

<h3><u>Explanation:</u></h3>

DNA is described here as the instructions that governs all the characters of an organism. Its actually a macro molecule which is a polymer of different thousands of nucleotides which is present in all cells and contain genetic information for running the characters of an organism.

Genes are described here as series of nitrogen bases governing a particular character or trait. Gene is actually a functional part of DNA which codes for a protein that governs a particular character of an organism.

Enzymes are proteins in nature. They are produced as a result of transcription and translation from DNA, and hastens different chemical processes of a metabolic activity.

The chromosomes are the condensed form of DNA. They are seen in the cells prior to cell division, either mitosis or meiosis. They are half obtained from father and the other half from mother, leading to variations among the offsprings.
