Definition Of Genetics Gene

A linear sequence of nucleotides along a segment of dna that provides the coded instructions for synthesis of rna which when translated into protein leads to the expression of hereditary character.

Definition of genetics gene. Genetics definition the science of heredity dealing with resemblances and differences of related organisms resulting from the interaction of their genes and the environment. German gen from gen begetting in greek words such as genos race. Clinical genetics the diagnosis prognosis and in some cases the treatment of genetic diseases. A hereditary unit consisting of a sequence of dna that occupies a specific location on a chromosome and is transcribed into an rna molecule that may function directly or be translated into an amino acid chain.

A gene is a highly specific sequence of nucleotide monomers that can fully or partially regulate the expression of one or more traits in every type of living organism. Biochemical genetics the study of the fundamental relationships between genes protein and metabolism. Genetics definition is a branch of biology that deals with the heredity and variation of organisms. Gene definition the basic physical unit of heredity.

Genes are formed from deoxyribonucleic acid dna and in the case of some viruses ribonucleic acid rna polymers. Genetic counseling an important area within clinical genetics involving the diagnosis risk assessment and interpersonal communication. Genetics is a branch of biology concerned with the study of genes genetic variation and heredity in organisms. Genes exists in alternate versions or alleles that determine distinct traits that can be passed on from parents to offspring.

Mendel studied trait inheritance patterns in the way traits are handed down from parents to offspring. Though heredity had been observed for millennia gregor mendel a scientist and augustinian friar working in the 19th century was the first to study genetics scientifically. Genetic variation can be defined as the genetic makeup of organisms within a population change genes are inherited segments of dna that contain codes for the production of proteins. These include those resulting from the improper synthesis of.
