Q

Catastrophism

Study These Flashcards
A

Cuvier theory that species would die out in catastrophes and go extinct, resulting in new species being formed

24
Q

Uniformitarianism

Study These Flashcards
A

Lyell’s theory that changes in the earths crust during geological history having resulted from the action of continuous and uniform processes; the earth is millions of years old

25
Carrying Capacity
The number of people, other living organisms, or crops that a region can support without environment degradation
26
Acquired characteristics
Lamark’s theory of animals being changed by ‘vital forces’; modification in an organ or tissue during the lifetime of an organism due to use, disuse, or environmental effects, and not inherited
27
Natural Selection
The favoring of traits that result in differential fertility; Requires variation, means of trait inheritance, and differential fertility
28
Differential fertility
Variation in fertility of different groups or classes in the population
29
Mutation
Spontaneous change in the structure of a gene resulting in a variant form
30
Gene drift
Change in the frequency of an existing gene variant in a population due to random sampling of organisms
31
Gene flow
The transfer of genetic variation from one population to another; if the rate of gene flow is high enough then two populations are considered to have equal genetic diversity and therefore be a single population
32
Fitness
The genetic contribution of an individual to the next generations gene pool
33
DNA
Deoxyribonucleic acid; the code of someone’s human body. A molecule composed of 2 5-carbon sugars, 2 phosphates, and 2 bases.
34
Adenine
One of the four constituent bases of nucleus acid; paired with thymine in double stranded DNA
35
Guanine
One of the four constituent bases of nucleic acids; paired with cytosine in DNA
36
Cytosine
One of the four constituent bases of nucleic acids; paired with guanine in DNA.
37
Thymine
One of the four constituent bases of nucleic acids; paired with adenine in DNA.
38
Uracil
Compound found in living tissues, a constituent base of RNA; replaced by thymine in DNA.
39
Heredity
Genetic inheritance; the rules of the human body
40
Prokaryotic
A unicellular organism that lacks a membrane bound nucleus, mitochondria, or any other membrane bound organelle
41
Eukaryotic
An organism whose cells contain a nucleus surrounded by a membrane and whose DNA is bound together by proteins into chromosomes. They’re organized and work well with other cells; humans are just eukaryotic colonies.
42
Organelle
Any of a number of organized or specialized structures within a living cell. (In a eukaryotic cell: 1. nucleus 2. mitochondria 3. ribosomes)
43
Nucleus
A dense organelle present in most eukaryotic cells, typically and single round structure bounded by a double membrane, containing genetic material.
44
Mitochondria
An organelle found in large numbers in most cells, in which the biochemical processes of respiration and energy production occur. The powerhouse of the cell; they release ATP which we run on. Mitochondrial DNA is different than your cellular DNA.
45
Ribosome
A minute particular consisting of RNA and associated proteins, found in large numbers in the cytoplasm of living cells. They manufacture protein and synthesize polypeptides.
46
Pleiotropy
The production by a single gene of two or more apparently unrelated effects. Genes work in nested physiological pathways, so they never never have just a single effect.
47
Hardy-Weinberg
A basic principle in genetics: 1. there is a simple relationship between the frequencies of alleles in the gene pool and the frequencies of genotypes in the population; 2. this relationship will be perpetuated indefinitely in future generations. This only describes a population that’s stable and unchanging.
48
Genotypic frequency
The number of individuals in a population with a given genotype divided by the total number of individuals in the population; proportion of members of a group with a specific genotype.
49
mRNA
Messenger RNA. It’s function is to copy sections of DNA inside the nucleus and then carry it to the ribosome to transcribe and translate into protein production.
50
tRNA
Transfer RNA. Delivers amino acids according to the sequence specified by the DNA
51
Amino Acid
Three base pairs form a codon, which specifies an an amino acid. 64 possibilities but only 20 distinct amino acids found in nature. They can be redundant and formed the same by different codons.
52
Codon
A sequence of three nucleotides that together form a unit of genetic code in a DNA or RNA molecule.
53
Stop Codon
A nucleotide triplet within messenger RNA that signals a termination of translation into proteins. Stops the production of protein.
54
Protein
A molecule composed of polymers of amino acids joined together by peptide bonds. Produced in the ribosomes of your cells.
55
Gene
A sequence of DNA that specifies the order of amino acids in a protein.
56
Gamete
A mature haploid male or female germ cell that is able to unite with another of the opposite sex in sexual reproduction to form a zygote.
57
Allele
One of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome.
