Cards

Term
DNA
Definition
Deoxynucleic Acid (DNA) is the code at which we create proteins that show (or Don't show) as traits in our physical beings.
Term
Nuclear DNA
Definition
DNA that is found within the nucleus of our each cell.
Term
Mitochondrial DNA
Definition
DNA that is found in the mitochondria of our cells. There can be 1 - 100 individual mitochondria within EACH cell. This DNA is smaller with only 37 chromosomes.
Term
Gregor Mendel
Definition
Mendel wrote about and studied principles of heredity. Pea Plant study. P - F1 - F2 generations. True-breeding plants (Homozygous) and created hybrid plants (Heterozygous).
Term
Chromosome
Definition
Bodies found in the nucleus of our cells that hold our hereditary materials.
Term
Gene
Definition
Sequence of base pairs (A-T, C-G) in a DNA molecule that code specific proteins.
Term
Allele
Definition

The alternative form of a gene. (A = tall OR a = short)

'A' and 'a' and the two alleles for height in this specific example.

Term
Dominant
Definition
A trait that is SEEN in a heterozygous organism is considered to be the 'Dominant' trait.
Term
Recessive
Definition
A trait that does NOT show in a heterozygous organisms.
Term
Codominant
Definition
When two alleles of the same gene are present and both are EXPRESSED in the organism.
Term
Locus
Definition
The position on a chromosome of a gene or mutation.
Term
Gene Pool
Definition
a the group of genes available within an interbreeding population of a species.
Term
Polypeptide
Definition
Group of amino acids (peptides) that become a protein that codes for a specific trait.
Term
Protein
Definition
A group of amino acids (peptides) that group in threes and form a protein that when paired with other proteins expresses (OR doesn't express) a trait in an individual.
Term
Protein Synthesis
Definition
A process by which biological cells generate new cells to balance for the loss of cells via degradation or export.
Term
Amino Acid
Definition
Building blocks of proteins. 3 amino acids make 1 protein.
Term
Enzyme
Definition
A molecule that makes a chemical reaction occur, slow down, or speed up with out altering the desired action or result.
Term
Lipids
Definition
compounds that include fats, oils, and waxes.
Term
Carbohydrates
Definition
organic compounds that are made of carbon, oxygen, and hydrogen. An example is sugars or starches like potatoes.
Term
Codon
Definition
3 base pair sequence of a DNA molecule that code for a specific amino acid.
Term
Autosome
Definition
All chromosomes except sex chromosomes.
Term
Sex Chromosomes
Definition
X (in females) and Y (in males) chromosomes. Females typically have XX as their pair whereas males typically have XY as their chromosomal pair.
Term
Karyotype
Definition
The standard for chromosomal organization and classification.
Term
Mitosis
Definition
Form of cell division geared towards growth and cell replacement.
Term
Meiosis
Definition
Specialized cell division that is specific to reproduction. This happens in the testes and ovaries to produce gametes or sex cells.
Term
Gamete
Definition
Sex cell from meiosis that has half of a human chromosome set (23 chromatids). This is represented as either a ovum in females or sperm in a male.
Term
Linkage
Definition
The association of genes that are on the same chromosome.
Term
X Chromosome
Definition
the larger of the two sex chromosomes. Females have two X's and males only have one.
Term
Y Chromosome
Definition
The smaller of the two sex chromosomes. Females typically have 0 Y chromosomes whereas males are heterozygous with 1 Y and 1 X.
Term
X-linked
Definition
Refers to genes on only the X chromosomes meaning that males and females can both be affected/express them. Males would only receive any of this information from their mothers as they receive a Y from their fathers.
Term
Y-linked
Definition
Refers to genes only on the Y sex chromosome meaning that males are the only ones affected by these genes/expressions.
Term
Mutation
Definition
The way new variants enter the species. The change of a genetic code via insertion, deletion, or rearrangements of genes.
Term
Independent Assortment
Definition
Differing traits are inherited independently of one another. Whether I am tall or short is unrelated to the color of my eyes.
Term
Segregation
Definition
The separation of hereditary traits into separate sex cells. These sex cells therefore contain either one or the other factors of a trait.
Term
Phenotype
Definition
The observable (generally) trait of an individual. Eye color, height, skin color, etc.
Term
Genotype
Definition
The genes on the chromosomes that make a trait.
Term
Deletion
Definition
When a chromosome itself breaks. This section is then not included in the second generation cell and the deleted section is lost.
Term
Inversion
Definition
When part(s) of a chromosome break and the reunite in a reversed order. No lost/gained material BUT the alleles and their positions are altered.
Term
Duplication
Definition
When a section of the chromosome is repeated.
Term
Translocation
Definition
When a section of a chromosome breaks off and the reattaches in a different location to other non homologous chromosomes.
Term
Rh blood type
Definition
A blood-type system consisting of 2 major alleles.
Term
Rh negative blood type
Definition
When your blood does not contain a certain protein on the red blood cells.
Term
Antibodies
Definition
Proteins manufactured by the body to neutralize or destroy an antigen.
Term
Antigen
Definition
a substance that stimulates the production or mobilization of antibodies. Antigens can be foreign proteins, toxins, or bacterium.
Term
DNA Replication
Definition

[image]

The process by which one DNA molecule/strand becomes two identical strands.

Term
Homozygote
Definition
An individual with two identical alleles that code for a particular gene. This is like organisms in true-breeding.
Term
Heterozygote
Definition
An individual with different alleles that code for a gene. This is generation F1 in the pea plant experiment.
Term
Epigenetics
Definition
The study of gene expression. This is not a change to the actual genetic code but just what genes are turned on and off at certain places and why.
Term
Stem Cell
Definition
The original cells. These cells are capable of becoming ANY cell that we will have as a complete organism. We start as stem cells and over time parts of the DNA in the turns on or off to determine what type of cell it is. (Skin, Cheek, Bone, Brain, etc.)
Term
Clone
Definition
To create a complete copy of an organism in its entirety that has the exact genetic make up.
Term
Eugenics
Definition
Movements or attempts to improve the human species through various tests and means. Some are good while others are horrific.
Term
Point Mutation
Definition
Mutation affecting only one or very few nucleotides in a gene sequence.
Term
Genome
Definition
Complete set of an organisms genes or genetic material.
Term
Zygote
Definition
A diploid cell resulting from two haploid cells fusing (gametes); a fertilized ovum.
Term
Punnett Squares
Definition
