1

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

dna

2

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

Nucleotides

3

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

Chargaff’s Rules

5

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.

6

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

Mutations

7

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

Adaptation

8

a group of living organisms consisting of similar individuals capable of exchanging genes or interbreeding.

species

9


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

evolution

10

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

Fossils

11

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

Fossil Record

12

Charles Robert Darwin, FRS FRGS FLS FZS was an English naturalist, geologist, and biologist, best known for his contributions to the science of evolution.

13

a distinguishing quality or characteristic, typically one belonging to a person

trait

14

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

Selective breeding

15

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.

Natural Selection

16

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.

Generation Time

17

populations evolve to become distinct species.

Speciation

18

A primate is a mammal of the order Primates. In taxonomy, primates include two distinct lineages, strepsirrhines, and haplorhines

Primates

19

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

Hominid

20

Homo sapiens is the binomial nomenclature for the only known extant human species. Homo is the human genus, which also includes Neanderthals and many other extinct species of hominin; H. sapiens is the only surviving species of the genus Homo
