|
|
Small circular RNA molecules that infect plants |
VIROIDS |
|
|
When cytoplasm divides |
CYTOKINESIS |
|
|
This substance is a protein secreted by other cells of the body that tells cells to divide |

|
|
Nuclear Division |
MITOSIS |
|
|
Noncoding regions of pre-mRNA that must be removed in eurkaryotic mRNA during processing |

|
|
Physical or chemical agents that cause DNA mutations |
MUTAGENS |
|
|
Creation of genetically identical offspring by a single parental cell |
ASEXUAL REPRODUCTION |
|
|
Genes located close together on the same chromosomes and tend to be inherited together |
LINKED GENES |
|
|
The variation among characters such as having white flowers instead of purple flowers |
TRAIT |
|
|
The structure forms between two new plant cells. It will become the new cell wall. |
CELL PLATE |
|
|
We get two alleles for each character. The one that determines the appearance of an organism is... |
DOMINANT ALLELE |
|
|
The period of the cell cycle that a cell will spend the most time in |
INTERPHASE |
|
|
Nearly 16 million men may be related to this man |
GENGHIS KHAN |
|
|
The term used for egg and sperm. These cells have half the number of chromosomes |
GAMETES |
|
|
Animals are _______ organisms because boy (somatic) cells contain pairs of homologous chromosomes |
KINGDOM |
|
|
Synthesis of protein from mRNA |
TRANSLATION |
|
|
Represents every three nucleotides on a mRNA molecule |
CODON |
|
|
The mating of an individual of unknown genotype and a homozygous recessive individual to ascertain the unknown individuals genotype |
TEST CROSS |
|
|
A sperm or egg carries only one allele for each inherited character because allele pairs separate from each other during the production of gametes. It is a Mendel Law. |
LAW OF SEGREGATION |
|
|
Prokaryotes reproduce via this type of cell division |
BINARY FISSION |
|
|
DNA is replicated via the ______ model because half of parental DNA is conserved in each daughter molecule |

|
|
A heritable feature among individuals such as height and flower color |
CHARACTER |
|
|
The term used for the position of a gene on a chromosome |
LOCUS |
|
|
Type of cell division that results in haploid gametes |
MEIOSIS |
|
|
We call two matching pairs of chromosomes... (eg. We have two copies of most chromosomes in our body, the exceptions being the sex chromosomes in males) |
HOMOLOGOUS |
|
|
This is seen when both alleles are expressed resulting in a phenotype that is a mix of the two parents. (eg. When mating snap dragon using a red flower with a white one resulting in pink offspring) |
INCOMPLETE DOMINANCE |
|
|
When a crossover event occurs during prophase 1. The site where the crossover event occured. |
CHIASMA |
|
|
To look for chromosomal abnormalities, a ____ is performed to see the chromosomal pairs during metaphase of mitosis |

|
|
A gene located on either sex chromosome |

|
|
Changing DNA into mRNA |

|
|
An organisms physical appearance such as having purple flowers |

|
|
A critical point in the cell cycle that tells the cell whether or not cell division can proceed |
CHECK POINT |
|
|
When one gene influences many characters |
PLEIOTROPY |
|
|
During meiosis if a chromosome pair fails to separate properly resulting in the wrong number of chromatids in the gametes. |
NON-DISJUNCTION |
|
|
Geneticist construct _____ to describe the inheritance of traits between family members. |

|
|
The genetic makeup of an organism such as Pp or pp, or PP which will help determine a plants flower color. |
GENOTYPE |
