A conceptual approach. Sister chromatids are duplicates and except for errors in replication are identical in sequence. The chromosomes align in a single plane. Crossing over occurs in meiosis I but not in meiosis II. G1 occurs before S phase and G2 occurs after S phase. XX in females and XY in males.

Prokaryotes usually have a single molecule of DNA. Generally, chromosomes of eukaryotes are circular. Eukaryotes usually have multiple chromosomes. Eukaryote chromosomes are usually linear.

In eukaryotes, chromosomes do not contain a. Prokaryotic chromosomes do not have telomeres because they a. In prokaryotes, replication usually begins at a specific place on the chromosome called the a.

The highly organized internal scaffolding of the nucleus is called the a. The attachment point on the chromosome for spindle microtubules is the a.

The cell divides. Which of the following occurs during prometaphase? The chromosomes align in a single plane. DNA is replicated. Microtubules attach to the kinetochores.

Mitotic spindles form. The two sister chromatids separate.

Chromosome movement during anaphase is a result of a. Pea plants have seven different types of chromosomes. A chromosome with a centromere at the very end is called a. A dividing eukaryotic cell is treated with a drug that inhibits the molecular motors associated with kinetochores.

At which cell cycle stage would it stop? The nucleus of a megaspore in a pea ovary would contain how many chromosomes? A nucleus in the pea endosperm contains how many chromosomes? How many different combinations in the gametes are possible? As in 5. The figure shows a chromosomal separation taking place. The letters stand for genes; capital and lowercase stand for different alleles.

The diploid chromosome number in this organism is four. What process is shown? In a flowering plant, the male part of the flower the stamen produces haploid microspores that divide by to produce sperm. A pollen grain that lands on a stigma grows a pollen tube to deliver to the ovary.

Fusion of a sperm with an egg produces a a. To provide food for the developing embryo, a tissue called endosperm is produced through double fertilization. Endosperm has a ploidy of a. What might be the result if breakdown of the shugoshin protein were premature? The cohesion protein would hold the chromosome arms together longer. The separation of homologous chromosomes would occur prematurely.

The separation of sister chromatids would occur prematurely.

Sister chromatids would never separate. As in humans, sex chromosomes determine sex: XX in females and XY in males. What is the total number of telomeres in a rat cell in G2?

What is the total number of chromosomes present in the cell during metaphase I of meiosis? What is the total number of chromosomes in a polar body cell from a rat? What evidence is there that viruses evolved after, not before, cells? Viruses can reproduce only within host cells. Thus, they must have evolved after cells. Section 2. Why is mitosis important within the cell cycle?

A single cell and all its genetic information is duplicated. Each cell contains a full complement of chromosomes. Explain why mitosis does not produce genetic variation and how meiosis leads to the production of tremendous genetic variation.

Mitosis produces cells that are genetically identical to the parent cell. Meiosis includes two distinct processes that contribute to the generation of genetic variation: Crossing over shuffles alleles on the same chromosome into new combinations, whereas the random distribution of maternal and paternal chromosomes shuffles alleles on different chromosomes into new combinations.

For example, karyotypes that extract chromosomes from a single cell and photograph them to look for abnormalities are done on metaphase, rather than interphase, cells. In metaphase, chromosomes are condensed and are more easily visualized. List and briefly describe the three major cell cycle checkpoints. For each checkpoint, predict the consequences if the checkpoint failed to work properly. If the checkpoint failed, the cell would proceed into S without the necessary enzymes, causing the DNA not to be replicated properly or completely.

Alternatively, the cell might divide without the genetic material having been replicated, causing the daughter cells to receive incomplete genetic information. Both predictions are reasonable based on information in the chapter. This checkpoint depends on tension at the kinetochores of each chromosome. Describe what is happening to chromosomes during the five substages of prophase I. Leptotene — chromosomes contract and become visible Zygotene — chromosomes continue to condense and homologous chromosomes pair up and begin synapsis Pachytene — chromosomes become shorter and thicker, synaptonemal complex develops between homologous chromosomes.

Diplotene — centromeres of paired chromosomes move apart — the two homologs remain attached at each chiasma Diakinesis — centromeres have moved apart Section 2. Describe the difference between the centromere and kinetochore.

A centromere is the physical location on a chromosome where the kinetochore and spindle microtubules attach. The kinetochore is composed of proteins that assemble on the centromere to provide a site for the spindle microtubules to attach. Describe the difference between G1 and G2 of the cell cycle.
