It is the sequence of these four nucleobases along the backbone that encodes genetic information. RNA strands are created using DNA strands as a template in a process called transcription, where DNA bases are exchanged for their corresponding bases except in the case of thymine (T), for which RNA substitutes uracil (U).

The storage, transfer, and expression of genetic information in biological organisms, [14] as manifested by the passing on of phenotypic traits from parents to their offspring, either through sexual or asexual reproduction. Offspring cells or organisms are said to inherit the genetic information of their parents. heritability 1.
Mendel called the information factors; however, they later became known as genes. Genes are the basic units of heredity in living organisms. They contain the information that directs the physical development and behaviour of organisms. Genes are made of DNA. DNA is a long molecule made up of individual molecules called nucleotides. Genetic ...
Human genetics is the study of inheritance as it occurs in human beings.Human genetics encompasses a variety of overlapping fields including: classical genetics, cytogenetics, molecular genetics, biochemical genetics, genomics, population genetics, developmental genetics, clinical genetics, and genetic counseling.
The presence of more than one different ploidy level, i.e. more than one number of sets of chromosomes, in different cells of the same cellular population. [12] mobile genetic element (MGE) Any genetic material that can move between different parts of a genome or be transferred from one species or replicon to another within a single generation.
This information is the instructions for the construction and operation of a living organism. The information within a particular gene is not always exactly the same between one organism and another, so different copies of a gene do not always give exactly the same instructions. Each unique form of a single gene is called an allele. As an ...
