Question

What is the segment of DNA?

Answer 1

One or more genes influence a phenotype, which is a characteristic. Abnormal genes and genes created as a result of new mutations can also cause certain characteristics. The size of genes varies depending on the code or protein they create. The DNA of every cell in the human body is identical. The differences between the cells are due to the various types of genes that are activated, resulting in the production of a variety of proteins.
Genes, like chromosomes, are arranged in pairs. Each parent has two copies of their genes, and each parent passes one copy of their genes down to their children. This is why the child shares many features with both parents, such as hair colour and eye colour.

Complete answer:
The functional regions of DNA are known as genes. Deoxyribonucleic acid (DNA) is a type of nucleic acid that is made up of deoxyribonucleic This is the smallest unit of DNA capable of performing a function on its own. Because they can produce mRNA, genea are the functional units of DNA. The information needed to build and organise cells is contained in DNA molecules. The functional parts of DNA are known as genes.
The piece of DNA that codes for a functioning protein is known as a gene. The genes of parents are passed on to their children. They pass along genetic information from generation to generation.
Because genes are made of DNA, they are functional units of heredity. The chromosome is made up of DNA that contains a large number of genes. Each gene contains a unique set of instructions for a certain function or protein coding. Genes, in layman's words, are responsible for heredity.

Note:
Functions of genes:
The functions of DNA and RNA are controlled by genes.
Proteins are the most significant components in the human body since they not only serve as building blocks for muscles, connective tissue, and skin, but they also play a role in enzyme manufacturing.
These enzymes play a crucial part in a variety of chemical processes and reactions in the body. As a result, protein synthesis is responsible for all of the body's actions, which are largely controlled by genes.
Genes are made up of a distinct collection of instructions or functions. The globin gene, for example, was told to make haemoglobin. Haemoglobin is a protein that aids in the transport of oxygen throughout the body.
