| Term | Definition |
|---|
| Asexual cell and asexual organismal reprod. of euk. both require _____ which divides the cell nulear material | mitosis |
| sex organismal reprod. of animals requires _____ which divides the cell material | meiosis |
| divides so that gentic of the offsprinmg is recombined | meiosis |
| divides so that gentics is not recombined is | mitosis |
| longest lasting cell cycle phase | interphase |
| cell phase that is not part of cell reproduction | interphase |
| g1, s, g2 are phases that subdivide | interphase |
| a euk cells dna is duplicated during | S |
| during whish phase is the dna divided | M |
| all humans have 23 ppaires of | chromosomes |
| cytokinesis in an animal cell is accomplished by formation of a | contractile ring |
| cytokinesis in a plan cell is accomplished by a | cell plate |
| syntheseis of new DNA that occurs in euk cells that will divide there nucleus results in chromosomes with two __ | chromatids |
| during cell division prok cells divide there nucleus by mitosos | false |
| during cell division , prok cells divide there cells by forming a cell plate | false |
| the proteins that contrinute to chromate structe of cells in interphase are | histones |
| the proteins that contribute to chromosome structure and there eventual involvment in nuclear phases are | cohesins |
| anaphase | nchromatis are separated to each daugher cell |
| prophase | nuclear envelpoe disapperaring |
| interphase | includes cell growth, organell rep, dna rep |
| telophase | nuclear envelope appears |
| metaphase | spindle is mature |
| synapsis occurs | prophase |
| tetrads form | prophase |
| haplod set of copied chromosomes line up and come into one chromatid | metaphase || |
| if tetrads and dyads dont seperate this error occurs | non disjunction |
| in axex reoriduction organisms the principle and only cause of variation is | point mutation |
| if meiosis in humans goes bad | plody variation |
| which sex chromosomes is not tolerated in human | Y |
| medel disc that factors were on chrom | false |
| mendel discovered that factors were segments of dna molcules and called trhem genes | false |
| mendel laws of inheritances have a basis in meiosis | true |
| allele is on the sex chromosomein humans, eye color | sex linked |
| human ABO blood type is had this way | codominace |
| two geness code for a characteristic | epistasis |
| one trait h as many genes | polygentic |
| boldness on humans in | sex influenced |
| what happens in anaphase 1 | the homologues separate |
| what happens in prophase || | a haploid exsits in cell |
| what happens in prophase 1 | crossing over |
| what happens in telophase | a non copied haploid exists |
| what happens in metaphase | | homoloughe chroms are lined up at cell equator |
