Flashcards in natural Deck (20):
Deoxyribonucleic acid is a molecule that carries the genetic instructions used in the growth, development, functioning and reproduction of all known living organisms and many viruses
Nucleotides are organic molecules that serve as the monomer units for forming the nucleic acid polymers deoxyribonucleic acid and ribonucleic acid, both of which are essential biomolecules in all life-forms on Earth
Chargaff's rules state that DNA from any cell of all organisms should have a 1:1 ratio (base Pair Rule) of pyrimidine and purine bases and, more specifically, that the amount of guanine is equal to cytosine and the amount of adenine is equal to thymine
they found dna
Watson and Crick
Rosalind Elsie Franklin was an English chemist and X-ray crystallographer who made contributions to the understanding of the molecular structures of DNA, RNA, viruses, coal, and graphite.
In biology, a mutation is the permanent alteration of the nucleotide sequence of the genome of an organism, virus, or extrachromosomal DNA or other genetic elements
Nicolas Cage is Charlie Kaufman, a confused L.A. screenwriter overwhelmed by feelings of inadequacy, sexual frustration, self-loathing, and by the screenwriting ambitions of his freeloading twin brother Donald
a group of living organisms consisting of similar individuals capable of exchanging genes or interbreeding.
the process by which different kinds of living organisms are thought to have developed and diversified from earlier forms during the history of the earth
A fossil is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, hair, petrified wood, oil, coal, and DNA remnants
fossil record definition. A term used by paleontologists ( see paleontology ) to refer to the total number of fossils that have been discovered, as well as to the information derived from them
Charles Robert Darwin, FRS FRGS FLS FZS was an English naturalist, geologist, and biologist, best known for his contributions to the science of evolution.
a distinguishing quality or characteristic, typically one belonging to a person
Selective breeding is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits by choosing which typically animal or plant males and females
Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in heritable traits of a population over time.
In population biology and demography, the generation time is the average time between two consecutive generations in the lineages of a population. In human populations, the generation time typically ranges from 22 to 32 years.
populations evolve to become distinct species.
A primate is a mammal of the order Primates. In taxonomy, primates include two distinct lineages, strepsirrhines, and haplorhines
The Hominidae, whose members are known as great apes or hominids, are a taxonomic family of primates that includes eight extant species in four genera
