- A number of different Markov models of DNA sequence evolution have been proposed. These substitution models differ in terms of the parameters used to describe...
record of evolution left in organisms' genomes: dating when species diverged through the molecular clock produced by mutations. For example, these DNA sequence...- Molecular evolution describes how inherited DNA and/or RNA change over evolutionary time, and the consequences of this for proteins and other components...
Deoxyribonucleic acid (/diːˈɒksɪˌraɪboʊnjuːˌkliːɪk, -ˌkleɪ-/ ; DNA) is a polymer composed of two polynucleotide chains that coil around each other to...- Junk DNA (non-functional DNA) is a DNA sequence that has no relevant biological function. Most organisms have some junk DNA in their genomes—mostly pseudogenes...

Mutation (redirect from DNA mutations)organism, virus, or extrachromosomal DNA. Viral genomes contain either DNA or RNA. Mutations result from errors during DNA or viral replication, mitosis, or...
argues that both bouts of mechanical evolution were motivated by similar selective forces: the need for accurate DNA replication without loss of viability...- Extrachromosomal DNA (abbreviated ecDNA) is any DNA that is found off the chromosomes, either inside or outside the nucleus of a cell. Most DNA in an individual...
genomic DNA. In this context, the standard genetic code is referred to as translation table 1. It can also be represented in a DNA codon table. The DNA codons...- Non-coding DNA (ncDNA) sequences are components of an organism's DNA that do not encode protein sequences. Some non-coding DNA is transcribed into functional...
The timeline of human evolution outlines the major events in the evolutionary lineage of the modern human species, Homo sapiens, throughout the history...- Genetics (section DNA and chromosomes)environment to the rate at which genetic evolution occurs. One important development was chain-termination DNA sequencing in 1977 by Frederick Sanger....

Transposable element (redirect from DNA transposable element)of the mass of DNA in a eukaryotic cell. Although TEs are selfish genetic elements, many are important in genome function and evolution. Transposons are...
Human genome (redirect from Human DNA)nucleic acid sequences for humans, encoded as DNA within the 23 chromosome pairs in cell nuclei and in a small DNA molecule found within individual mitochondria...- Molecular phylogenetics (redirect from DNA taxonomy)actions of evolution are ultimately reflected in the genetic sequences. At present, it is still a long and expensive process to sequence the entire DNA of an...
