Question 19. Answer: condensation.
Explanation: The chromosomes condense during various phases of mitosis, it begins with the prophase. This condensation makes the chromosomes visible under light microscope.
Question 20. Answer: replication of DNA occured with out errors.
Explanation: When a cell crosses through G2 to M phase there are points called check points. These points ensure that a cell divides properly and there are no errors in DNA replication.

Two genetically identical daughter cells are formed. d Crossing over occurs during prophase e. It consists of two nuclear divisions. Quession 15 How does a nucleus in G2 difler from a nucleus in G17 Select one a. DNA synthesis occurs only in G1 phase. b Inactive cells are arrested only in G2...
Unit 3 Study Resource Meiosis • Process by which diploid cells create haploid cells NOT part of the cell cycle > only some cells ever undergo meiosis During meiosis I, homologous chromosomes line up to allow them to be separated into two new cells o They can become "tangled" during this phase, which leads to crossing-over (rearranging the alleles) O Result of meiosis I is two non-identical haploid cells Meiosis Il looks very similar to mitosis, in that sister chromatids...

2. Match the phase to the description. NOTE: this question might look a little different on the Moodle activity. Read carefully. Phase Hanne Description of Events in the Life of a Cell • Anaphase of muitosis A. The combined phases of GI/Go+S+G2 • Gl phase • G2 phase B. The cell is metabolically active; the cell duplicates argumelles and cytosolie components; the cell size starts to increase the cell makes proteins which will soon be used in DNA synthesis C....
Question 26 (1 point) How is cytokinesis in plant cells different from cytokinesis in animal cells? Cytokinesis in plant cells requires formation of a cell plate; cytokinesis in animal cells requires formation of a ring of actin. Cytokinesis in plant cells occurs during G2; cytokinesis in animal cells occurs in the M phase of the cell cycle. Cytokinesis in plant cell results in one large cell with two nuclei; cytokinesis in animal cells results in two cells, each with one...

QUESTION 1 All organisms must duplicate their DNA with extraordinary accuracy before each cell division A mixture of proteins accompishes DNA replication. Each of the proteins act independent of one another yet held together in a large multi-enryme complex that moves rapidly along the DNA. Imagine a tiny sewing machine composed of protein parts and powered by nucleosidetriphosphate hydrolases Match the protein subunit or factor of the replication machine to the...
