Question

What is a gene?

Answer 1

There are two sorts of organisms: eukaryotic and prokaryotic. Eukaryotic organisms include animals, plants, and certain fungi, which have a nucleus that is positioned inside the cell membrane and carries genes. Certain bacteria are prokaryotic, which means they don't have a nucleus and have all of their genes on a single chromosome floating around in the cytoplasm.

Complete solution:
Each individual inherits one copy of each gene from each parent. Except for a few genes known as "Alleles," nearly everyone's genes are identical. Because they are parts of the same genes with tiny differences in DNA sequence bases, each individual has unique physical characteristics. Many genes are found on each chromosome, and some of them are given abbreviated names based on the condition trait. Protein synthesis necessitates the use of genes. However, the Genes are also responsible for a number of additional tasks. Genes that do not produce protein are converted to mRNA. Instead, microRNA that does not undergo protein synthesis aids in gene control.

Note:
Our bodies consist of a variety of cells, like liver cells, lungs cells, and so on, which join to form organs. All of the cells in the body's organs have various roles and emit different chemicals, but they all come from a single fertilised cell with the same DNA. Because different genes are expressed in different cells, their appearances and functions differ. The timing and manner in which a Gene is expressed are already encoded in the DNA.
