male reproductive cell
female reproductive cell
half of a chromosome
Cells with the haploid number of chromosomes. Gametes are created out of germ cells. The sperm and eggs involved in sexual reproduction are gametes.
Refers to the copy of a chromosomes that results from DNA replication and is still closely linked to its original.
a type of reproduction that does not require the union of female and male gametes
condensed form of chromatin visible during cellular division
reproduction involving the union of female and male gametes to form a zygote
chromosomes that carry information about same traits
phase of cell cycle where cell pinches off and divides in two
A cell with a complete set of chromosomes for a given species, half of which were inherited from each parent.
A cell containing half the full set of chromosomes
Chromosomes with matching information
An egg or sperm cell; a sex cell carries half the number of chromosomes found in other body cells.
Chromosomes that carry the genes that determine offspring gender; the X and Y chromosomes in humans.
barrel-shaped organelle found in most animal eukaryotic cells
A partition that is formed during telophase of cell division in plants and some algae and that separates the two newly formed daughter cells.
The deep groove formed when the cell membrane pinches inward during cytokinesis in cells without a cell wall.
segment of DNA
DNA strands wrapped around protein
2 parts of a chromosome
where chromatids are attached
like chromosomes that make up pairs
2 sets of chromosomes
1 set of chromosomes
chromosomes that are not sex chromosomes
determine sex of offspring
photo of chromosomes of dividing cell
cycle of growth and division
longest part of cell cycle
process that divides nucleus
uncontrolled cell growth
help chromatids move to opposite ends of cell
what are the steps of mitosis?
prophase, metaphase, anaphase, telophase
G 1 phase
first growth phase of cell cycle
DNA is copied
G 2 phase
preparing for nucleus to divide
G 1 checkpoint
checks for cell division to start
G 2 checkpoint
checks DNA replication before mitosis
chromosomes are lined up in the center of cell
chromosomes are pulled apart by spindle fibers
chromosomes are at opposite ends of cell
chromosomes wind up and become visible
a change or mistake in a gene
genetic rearrangement between non-sister chromatids occurs during Prophase I
chromosome pairs 23 in body
the only cells that can undergo meiosis
fibers that attach to sister chromatids
