What is Genetics? What does it study?

Genetics is a field of biological science, that specifically studies genetic material (DNA or RNA), and related alterations and abnormalities.

Genetic studies DNA, RNA, gene, chromosome, genome, mutations, epigenetics, phenotypes and genotypes. Let’s see each one by one.

Genetic studies DNA, its structure, function and related alteration. DNA is a nucleic acid and a genetic material.

Genetic studies RNA, its structure, function and how it forms proteins. It’s also a type of nucleic acid and genetic material of retrovirus.

Genetic studies genes which are functional pieces of DNA. It helps to understand how protein forms from a gene.

Genetic studies chromosomes, their structure and function. Structural studies help to understand how abnormalities occur by genetic factors.

Genetic studies a genome. Genomic studies let scientists understand the nature of complex diseases and abnormalities.

Genetic studies mutations. Any alteration in a DNA is known as mutation which is directly associated with an abnormal phenotype.

Genetic studies also include epigenetic evaluation which allows one to understand the pattern of gene expression.

Genes by the influence of environmental factors cause abnormalities, produce mutations or alter gene expression patterns.
