Definition
Answer
Molecule that stores genetic information
DNA
Study of heredity and variation
Genetics
Cell that contains 3 or more sets of chromosomes
Polyploid
Chemical subunit of DNA conding for certain traits
Gene
Location of a gene on a chromosome
Locus
Cell containing half of the genetic information
Haploid
Reproduction where a piece of an organism breaks off and grows
Fragmentation
Process where a genetically identical organism is created using a body cell
Clone
Reproduction involving the use of runners
Vegetative Reproduction
Production of a new organism in an outgrowth of the body
Budding
Process of passing traits from parents to offspring
Heredity
Cell containing the genetic information of 2 fused gametes
Zygote
Process where a male gamete fuses with a female gamete
Fertilization
Meiotic production of male and/or female gamtes
Gametogenisis
Production of polar bodies and egg cells
Oogenesis
Production of male sperm cells
Spermatogenisis
Type of cell division which yields sex cells in animals
Meiosis
The pair of similar chromosomes from each gamete that match
Homologous Chromosomes
A picture of each homologous pair of chromosomes
Karyotype
Pair of chromatids which forms in prophase
Sister Chromatids
Forms in Prophase one when homologous chromosomes group together
Tetrad
Important in both types of cell division during anaphase to pull apart chromatids
Spindle Fibres
Process in which tetrads are formed
Synapsis
Occurs when a piece from homologous pairs breaks off and switches DNA
Crossing Over
Definition
Answer
Rule stating that only one homologous pair can enter a daugther cell in meiosis
Reductive division
Failure of homologous chromosomes to seperate during meiosis
Non-Disjunction
3 chromosomes take the place of a homologous pair
Trisomy
1 chromosome is in the place of a homologous pair
Monosomy
Use of a needle to take fetal fluid to test for non-disjunction
Amniocentisis
Blood tests around 15-20 weeks of pregnancy testing for non-disjunction
Multiple Marker Testing
Testing the chrorion for non-disjunction
CVS
Technology which increases sperm count and includes In Vitro Fertilization
Assisted Reproductive Technology
Process in which cytoplasmic inheritance can be treated
Egg Swapping
Component of DNA which codes using complementary base pairings
Nitrogenous Bases
Component of DNA which is sometimes called pentose sugar
Deoxyribose
Section of DNA which can take an alternative form in the case of a mutation
Allele
A change in the genetic makeup of an allele
Mutation
A mutation which occurs due to environmental factors
Induced Mutation
A specific piece of DNA which can move places on a chromosome
Transposon
A "Barcode" which is capable of showing active genes/mutations using lights
Microarray
Mutation which occurs at a specific place on a gene
Point mutation
A cell which does not differentiate (Body Cell)
Autostome
A molecule which can cut a piece of DNA at a specific point
Restriction Enzyme
Species with a similar genome to humans used for tests
Mouse
Project to create the genomic sequence of humans
Human Genome Project
DNA sequence which can be inserted into a target cell
Vector
Fragment of DNA combined from 2 different sources
Recombinant DNA
The result of cutting a piece of DNA with a restriction enzyme
Sticky End
