Lab Practical Vocab

TermDefinition
telophase daughter nuclei reform
S phase during which dna is synthesized
anaphase chromosomes move towards opposite poles of the cell
prophase chromatin fibers become more condensed to form discrete chromosomes
interphase nucleus is well defined and bounded by the nuclear envelope. chromosomes are indistinct
prophase mitotic spindle begins to form by extending from the two centrosomes
anaphase centromeres separate and the sister chromatids are now individual chromosomes
mitosis nuclear division that distributes chromosomes equally to daughter cells
G2 cell continues to grow but is now completing preparations for mitosis
G1 first period of cell growth after mitosis is completed
telophase chromosomes become less distinct and chromatin forms as each chromosome becomes less tightly coiled
metaphase chromosomes align on an imaginary line equidistant from each pole
cytokinesis division of the cytoplasm
prometaphase nuclear envelope fragments and spindle fibers attach to kinetochores of chromatids
interphase includes G1, G2, and S phase
sister chromatids term used to describe the double stranded chromosomes present after dna replication
crossing over exchange of exact segments f chromosomes between nonsister chromatids
alleles alternate forms of a gene
cytokinesis division of the cytoplasm
synapsis pairing of homologous sister chromatids during prophase I of meiosis
homologous chromosomes pair of chromosomes containing genes for the same traits at the same loci
haploid term which describes cells containing one of each homologous chromosome pair
meiosis
tetrad complex composed of 4 strands of chromosomes which results from synapsis
mitosis type of cell division that results in the formation of 2 daughter cells genetically identical to parent cell
diploid term which describes cells containing homologous pairs of chromosomes
chromatin dna and protein complex present during interphase. chromosomes organized as long thin fibers which are indistinct
sister chromatids two identical copies of a chromosome held together by a centromere
chromosomes composed of dna and are visible as rod shaped structures during cell division in eukaryotes
