What are both chromosomes and genes made from?

Chromosomes and genes are both made from DNA, which is composed of sequences of nucleotides. Chromosomes are larger structures that consist of many genes. Together, they play crucial roles in heredity and function in living organisms.

1. Chromosomes : These are long, thread-like structures located within the nucleus of eukaryotic cells. Each chromosome consists of a single molecule of DNA that is tightly coiled and packaged with proteins called histones. This combination of DNA and proteins forms a complex known as chromatin, which helps in the organization and regulation of genetic information.

2. Genes : Genes are specific segments of DNA found on chromosomes. Each gene contains the instructions for synthesizing proteins or RNA molecules that perform various functions in the body. Genes are made up of sequences of nucleotides, which are the building blocks of DNA. There are four types of nucleotides in DNA, distinguished by their nitrogenous bases: adenine (A), thymine (T), cytosine (C), and guanine (G).

In summary, both chromosomes and genes are primarily made from DNA, with chromosomes being larger structures that contain many genes along with associated proteins.
