gamete
|
--a haploid REPRODUCTIVE CELL that unites with another haploid reproductive cell to form a ZYGOTE
|
is single but sounds like half; for sexual reproduction so only needs to supply half
|
|
binary fission
|
--a form of ASEXUAL REPRODUCTION in single celled organisms by which one cell DIVIDES into two cells of the same size
|
|
|
gene
|
--a SEGMENT OF DNA that is located in a chromosome and that codes for a specific hereditary trait
|
genes make up chromosomes
|
|
chromosome
|
--in a eukaryotic cell, one of the structures in the nucleus that are made up of DNA and protein; in a prokaryotic cell, the main ring of DNA
|
|
|
chromatid
|
--one of the two STRANDS OF A CHROMOSOME that becomes visible during meiosis or mitosis
|
|
|
centromere
|
--the region of the chromosome that HOLDS THE TWO SISTER CHROMATIDS TOGETHER during mitoses
|
central location
|
|
homologous chromosome
|
--chromosomes that have the SAME SEQUENCE OF GENES that have the same structure, and that pair during meiosis
|
homo=same
chromosomes have genes; pairs |
|
haploid
|
--describes a cell nucleus or organism that has only ONE SET OF UNPAIRED CHROMOSOMES
|
|
|
diploid
|
--a cell that contains TWO HAPLOID SETS of chromosomes
|
di, dip means two
|
|
zygote
|
--the cell that results from the fusion of gametes; FERTILIZED EGG
|
|
|
autosome
|
--any chromosome that is NOT A SEX CHROMOSOME
|
not X or little puny y
|
|
karyotype
|
--an array of the chromosomes found in an individuals cells at metaphase of mitosis and arranged in homologous pairs and in order of diminishing size; PICTURE
|
used to make familiar picture
|
|
cancer
|
--a tumor in which the cells begin DIVIDING AT AN UNCONTROLLED RATE and become invasive
