Flashcards in Evidence to evolution Deck (13)
The complete set of genetic material in a cell; an organism's complete set of DNA
the comparisons of genome sequences of different species. e.g. The human genome project in 2003.
Non-coding sequences of bases in the DNA
Endogenous retroviruses (ERV)
a retrovirus that has become part of an organisms genome and exists in every cell of the body. retroviruses store there genetic info as RNA not DNA
A process where the base sequence in RNA is copied during the synthesis of DNA
Mitochondrial DNA (mtDNA)
mtDNA is DNA found in the mitochondria of the cells, rather than in the nucleus
Inheritance of mtDNA
our mtDNA only come from the egg (i.e. the mother) as after Fertilisation that mtDNA is destroyed in the sperm.
Evidence from mtDNA
- mtDNA has a higher rate of mutation
- if mtDNA are identical they are closely related
- mtDNA makes it possible to track the routes of
migration of common ancestors
- important in mapping relationships between species
A comparison of the type and sequence of the amino acids in the protein of other species.
one of a group of proteins that appears to be in all species from bacteria to humans; the small protein call ubiquitin was so names because it is present in all types of cells
a great example of a ubiquitous proteins. Important in the electron transport system in cellular respiration which occurs in all cells.
the use of computers to describe the molecular components of living. Used to gain info about DNA, proteins.
