network that is essential for proper alignment and chromatid separation (Bharadwaj and Yu‚ 2004). Taxol form stable and dysfunctional microtubules which can no longer maintain shape‚ motility‚ signal transmission‚ and intracellular transport in interphase and stable microtubules fails to bind to centromere to align chromosomes in metaphase and separate non sister chromatids in anaphase. This induces cell cycle arrest; inhibit cellular replication and causes cell death (Rowinsky et al.‚

reforming closed membrane. The chromosomes are become less condensed. As the nuclear membranes re-form around each set of chromatids‚ the nucleoli also reappear. The chromosomes also unwind back into the expanded chromatin that is present during interphase. Telophase accounts for approximately 2% of the cell cycle ’s duration. Chromosomes are uncoiled from spindle fibers and lengthened. Spindle fibers degenerate. The division of one nucleus into toe genetically identical nuclei‚ is now

information and its genetic code to its daughter cells. Replication precisely copies DNA so that new molecules contain the same exact sequence of bases as the original strands. DNA replication occurs in the nucleus. It takes place during the S phase of interphase as DNA. The Steps of Replication: 1) First‚ helicase moves along the double helix unzipping the two strands. The strands separate as the hydrogen bonds between the bases break. 2) The unpaired nucleotides act as a template for the formation of

Draw a Punnett square for this cross. How many offspring would be predicted to have terminal flowers and be dwarf? (See Table 14.1.) 1. According to the law of independent assortment‚ 25 plants (1⁄16 of the offspring) are predicted to be aatt‚ or recessive for both characters. The actual result is likely
