Question

Where are genes located?
(a) Cell membrane
(b) Golgi apparatus
(c) Plastid
(d) Chromosome

Answer 1

Hint: These are present in 23 pairs in humans, and the number varies from species to species.
Chromosomes are the specialized structure that is formed during cell division by the condensation of chromatin. This chromatin consists of DNA, which is made up of genes. Therefore, genes are present in chromosomes. These chromosomes are found inside the nucleus of a eukaryotic organism.

Complete step-by-step answer:
Somatic cells have two sets of chromosomes and are diploid cells. The gametes consist of one set of chromosomes and are haploid in nature. Their number varies in different organisms but the same for the same species. The normal chromosomes have sizes varying from 1-30µ and 0.2 to 2µ, respectively.
DNA is known as the genetic material for most of the organism due to the presence of genes which stores all the information regarding our machinery. These DNAs are very long and are bonded with the help of a protein known as histone protein. This structure is known as beads on a string structure.
So, the correct answer is, “ chromosome.”

Note: Genes are the hereditary units that contain information and are transmitted from one generation to another. Almost all organisms have DNA in which genes are located, while in some viruses, mostly plant viruses have RNA as its genetic material.
