4 days ago · Gene structure and function, variation, and distribution are studied within the context of the cell, the organism (e.g. dominance ), and within the context of a population. Genetics has given rise to a number of subfields, including molecular genetics, epigenetics, and population genetics.

Jun 7, 2024 · Genetics arose out of the identification of genes, the fundamental units responsible for heredity. Genetics may be defined as the study of genes at all levels, including the ways in which they act in the cell and the ways in which they are transmitted from parents to offspring.

2 days ago · These genes make up different DNA sequences, together called a genotype, that is specific to every given individual, within the gene pool of a population of a given species. The genotype, along with environmental and developmental factors, ultimately determines the phenotype of the individual.
1 day ago · Deoxyribonucleic acid ( / diːˈɒksɪˌraɪboʊnjuːˌkliːɪk, - ˌkleɪ -/ ⓘ; [1] DNA) is a polymer composed of two polynucleotide chains that coil around each other to form a double helix. The polymer carries genetic instructions for the development, functioning, growth and reproduction of all known organisms and many viruses.
1 day ago · Genetic code refers to the instructions contained in a gene that tell a cell how to make a specific protein. Each gene’s code uses the four nucleotide bases of DNA: adenine (A), cytosine (C), guanine (G) and thymine (T) — in various ways to spell out three-letter “codons” that specify which amino acid is needed at each position within a ...
2 days ago · Phenotype refers to an individual’s observable traits, such as height, eye color and blood type. A person’s phenotype is determined by both their genomic makeup (genotype) and environmental factors.
Jun 25, 2024 · DNA, organic chemical of complex molecular structure found in all prokaryotic and eukaryotic cells. It codes genetic information for the transmission of inherited traits. The structure of DNA was described in 1953, leading to further understanding of DNA replication and hereditary control of cellular activities.
