Gene
section of a chromosome that codes for a protein or RNA molecule
Chromosome
structure made of DNA and associated with proteins on which genes are located
Chromatid
one of a pair of strands of DNA that make up a chromosome during meiosis or mitosis
Gamete
haploid cell that participates in fertilization by fusing with another haploid
Binary fission
form of asexual reproduction that produces identical offspring
Centromere
region joining two chromatids
Homologous chromosome
a member of a chromosome pair both of which are similar in shape, size, and the genes they carry
diploid
term used to indicate a cell containing two sets of chromosomes (2n), 1 set inherited from each parent
haploid
having only one set of chromosomes
zygote
fertilized egg cell
autosome
a chromosome that is not directly involved in determining sex
sex chromosome
one of a pair of chromosomes that are involved in detmining the sex of an individual
karyotype
array of the chromosomes found in an individuals calls arranged in order of shape and size
cell cycle
repeating five-phase sequence of eukaryotic cell growth and division
interphase
period between 2 mitotic or meiotic divisions of a eukaryotic cell during which the cell carries out the routine functioning, copies DNA, and prepares to divide
mitosis
process during cell division in which the nucleus of a cell divides into 2 nuclei, each with the some number and kind of chromosomes
cytokinesis
division of the cytoplasm that forms two seperate cells
cancer
disease charachterized by abnormal cell growth
spindle
structure composed of centrioles and individual hollow protien fibers that move chromosomes apart during cell division
meiosis
process during cell division in which the nucleus of a cell completes two succesive divisions that produce 4 cells, each with a chromosome number that has been reduced by half
crossing over
the exchange of reciprocal segments of DNA by homologous chromosomes at the beginning of meiosis;source of genetic recombination
independent assortment
random distribution of homologous chromosomes during meiosis
spermatogenesis
process by which gametes are produced in male animals
sperm
male gamete
oogenesis
process by which gametes are produced in female animals
ovum
a mature egg cell
asexual reproduction
reproduction that involves only one parent and results in genetically identical offspring
clone
organism produced by asexual reproduction that is genetically identical to its parent
sexual reproduction
reproduction in which gametes from opposite sexes or mating types unite to form a zygote
life cycle
entire lifespan of an organism; summary nof all the stages of an organism
fertilization
the process by which haploid gametes join to form a diploid zygote
sporophyte
diploid phase in the type of life cycle known as alteration of generations; diploid individual that produces spores
spore
an asexual, resting, reproductive haploid cell
gametophyte
haploid phase in the type of life cycle known as alteration of generations; haploid individual that produces gametes
