Bio 1500 Exam 4 Questions and Answers 100% Pass Genome - the haploid set of chromosomes in a gamete or microorganism, or in each cell of a multicellular organism. Chromatid - each of the two threadlike strands into which a chromosome divides longitudinally during cell division. Each contains a double helix of DNA. Sister Chromatids - A sister chromatid refers to either of the two identical copies (chromatids) formed by the replication of a single chromosome, with both copies joined together by a common centromere. Diploid - (of a cell or nucleus) containing two complete sets of chromosomes, one from each parent. Haploid - (of a cell or nucleus) having a single set of unpaired chromosomes. Cell Cycle - a series of events that takes place in a cell as it grows and divides. A cell spends most of its time in what is called interphase, and during this time it grows, 2100% Pass Guarantee Sophia Bennett, All Rights Reserved © 2025 replicates its chromosomes, and prepares for cell division. The cell then leaves interphase, undergoes mitosis, and completes its division. Metaphase plate - a plane cell section in the equatorial plane of the metaphase spindle having the chromosomes oriented upon it. Gametes - a mature haploid male or female germ cell that is able to unite with another of the opposite sex in sexual reproduction to form a zygote. Somatic Cells - any cell of a living organism other than the reproductive cells. Somatic cells - any cell of a living organism other than the reproductive cells. Aster - a star-shaped structure formed during division of the nucleus of an animal cell. Kinetochores - the place on either side of the centromere to which the spindle fibers are attached during cell division. Types of cells in which mitosis occurs - Somatic cells How does mitosis impact chromosome number of daughter cells compared to parental cells? - Retains the same number of chromosomes 2 Phases of the cell cycle before and after mitosis. - G2 before and G1 after. Where does the cell spend most of its time? Interphase or Mitosis? - Interphase 3100% Pass Guarantee Sophia Bennett, All Rights Reserved © 2025 What are the events that occur during Interphase? - G1 phase, S phase, G2 phase G1 phase - During G1 phase, also called the first gap phase, the cell grows larger and makes more of its ribosomes, organelles, and proteins. This phase ensures that division will produce functional daughter cells, ones that are the right size and have all the parts they need. If cells didn't grow before they divided, they would get smaller and smaller over generations, eventually becoming too small to functio
