mitosis/meiosis

vocab words

TermDefinition
mitosis process by which a cell divides its nucleus and contents
diploid (number) cell that has two copies of each chromosome,one from an egg and one from a sperm
chromosome (s) long, continuous thread of DNA that consists of numerous gene and regulatory information
interphase the resting phase between successive mitotic divisions of a cell or between the first and second of meiosis
crossing over the exchange of genes between homologous chromosome resulting in a mixture of parental characteristics in offspring
Anaphase third phase of mitosis during which chromatids separate and are pulled to opposite sides of the cell
haploid /monoploid cell that has only one copy of each chromosome and monoploid is single set of chromosome
daughter nuclei the two nuclei that result from the division of a single nucleus usually by mitosis
tetrad a group of set of four
gametogenesis process by which gametes are produced through the combination of meiosis and other maturational changes
meiosis form of nuclear division that divides a diploid cell into haploid cells important in forming gametes for sexual reproduction
metaphase second phase of mitosis when spindle fiber align the chromosome along the cell equator
cytokinesis process by which the cell cytoplasm divides
disjunction the normal separation or moving apart of chromosome toward opposite poles of the cell during cell division
variation the difference in physical traits of an individual from the group to which it belongs
telophase last phase of mitosis when a complete set of identical chromosomes is positioned at each pole of the cell the nuclear membranes start to form the chromosome begin to uncoil and the spindle fibers diassemble
replication process by which DNA is copied
synapsis the fusion of chromosome pairs at the start of meiosis
prophase first phase of mitosis when chromatin condenses the nuclear envelope breaks down the nucleolus disappears and centrosomes and centrioles migrate to opposite sides of the cell
centriole small cylinder -shaped organelle made protein tubes arranged in circle ,aids mitosis
