individual with the genotype RrTtpp is crossed with an individual of genotype RRTtPp Assume each trait is governed by complete dominance and that all gene loci are on different chromosomes The cross described above can result in offspring that display how many different phenotypes A one B two C three D four E six four centrosome How do the daughter cells at the end of mitosis and cytokinesis

chromosomes and half the amount of DNA D The daughter cells have the same number of chromosomes and the same amount of DNA E The daughter cells have the same number of chromosomes and twice the amount

centrosome C centriole D chromatid E kinetochore During which parts of a somatic cell cycle are chromosomes composed of two chromatids A from interphase through anaphase B from G1 of interphase through metaphase C from metaphase through telophase D from anaphase through telophase E from G2 of interphase through metaphase from G2 of interphase through metaphase If a cell has 8 chromosomes at metaphase of mitosis how many chromosomes will it have during anaphase A 1 B 2 C 4 D 8 E 16 16 A particular cyclin called cyclin E forms a complex with a cyclin dependent kinase called Cdk 2 This complex is important for the progression of the cell from G1 into the S phase of the cell cycle Which of the following statements is correct A The amount of cyclin E is greatest during the S phase B The amount of Cdk 2 is greater during G1 compared to the S phase C The amount of cyclin E is highest during G1 D The amount of Cdk 2 is greatest during G1 E The activity of the cyclin E Cdk 2 complex is highest during G2 the amount of cyclin E is highest during G1 Density dependent inhibition is explained by which of the following A As cells become more numerous they begin to squeeze against each other restricting their size and ability to produce control factors B As cells become more numerous the cell surface proteins of one cell contact the adjoining cells and they stop dividing C As cells become more numerous the protein kinases they produce begin to compete with each other such that the proteins produced by one cell essentially cancel those produced by its neighbor D As cells become more numerous more and more of them enter the S phase of the cell cycle as cells become more numerous the protein kinases they produce begin to compete with each other such that the proteins produces by one cell essentially cancel those produced by its neighbor Which of the following is true of a species that has a chromosome number of 2n 16 A The species is diploid with 32 chromosomes per cell B The species has 16 sets of chromosomes per cell C Each cell has 8 homologous pairs D During the S phase of the cell cycle there will be 32 separate chromosomes E A gamete from this species has 4 chromosomes each cell has 8 homologous pairs After telophase I of meiosis the chromosomal makeup of each daughter cell is A diploid and the chromosomes are each composed of a single chromatid B diploid and the chromosomes are each composed of two chromatids C haploid and the chromosomes are each composed of a single chromatid D haploid and the chromosomes are each composed of two chromatids E tetraploid and the chromosomes are each composed of two chromatids haploid and the chromosomes are each composed of two chromatids 1 Formation of four new nuclei each with half the chromosomes
