Points: 1
Any time in the cell cycle.
During G2 phase.
During the mitotic phase.
During the G1 phase.
During S phase.
The Gap 1, DNA synthesis, and Gap 2 phases of the cell cycle are collectively called
Points: 1
prophase.
interphase.
prephase.
mitosis.
anaphase.
Which of the following can produce an XYY individual after fertilization?
Points: 1
Nondisjunction of X sister chromatids during meiosis II
Nondisjuction of Y sister chromatids during meiosis II
Nondisjunction of X and Y chromosomes during meiosis I
Nondisjuction of two X chromosomes duing meiosis I
1)cells is the most adult bodies are in the restin state known as G0 phase. G0 phase can be induced during the G1 phase.
2)The Gap 1, DNA synthesis, and Gap 2 phases of the cell cycle are collectively called interphase.
3)Non disjunction of Y sister chromatids during meiosis II can produced an XYY individual after fertilization.

Can you please help me with this problem:
1. A cell in G2 of interphase has 10 chromosomes. How many chromosomes and DNA molecules will be found per cell when this original cell progresses to the following stages: a. Metaphase 1 of meiosis b. Prophase II of meiosis c. G1 phase, following the conclusion of mitosis d. Anaphase 1 of meiosis 2. Draw a pair of homologous chromosomes in G2 of the cell cycle. These chromosomes carry two different genes...
• In the cell, DNA is duplicated in the G1 phase S phase G2 phase Division stage Which of the following statements is true? Chromatin is more compacted in prophase than during the G2 phase The key even of Sphase is the segregation of sister chromatids • • The mitotic spindle first appears during anaphase The cell increases in size during metaphase Which of the following correctly represents the order of the phases in the cell cycle? Mitosis, S phase,...
Question 12 (2 points) Which of the following events of meiosis leads to the creation of haploid cells by the end of Telophase 1 of meiosis? 1) sister chromatids separate during Anaphase II 2) homologous chromosomes synapse and cross over during Prophase 3) homologous chromosomes separate during Anaphase 4) random fertilization 5) nondisjunction
Simulate meiosis by drawing One pair of chromosomes and no crossing over Instructions: Set up your cell. The cell you start with should be: A diploid cell It should contain 1 pair of homologous chromosomes It should be in G1 of the cell cycle, before DNA replication occurs Be sure to show 2 genes that are both heterozygous . Go through the steps of meiosis. Be sure to show and label these in your pictures: Label homologous chromosomes and sister...
if a eukaryotic cell contains 20 chromosomes during interphase how many sister chromatids will be present during the mitotic prophase and anaphase? please explain answers
Can someone please check my answer? Understanding chromosome number and behavior during cell division is an important concept in genetics. Fill out the chart below for each phase of mitosis in terms of N (where N = haploid number). For example, humans have a haploid number of 23. There are 46 chromosomes (2N) present in prophase of mitosis. Each chromosome is present in its replicated form (i.e. as sister chromatids) so there will be 2 chromatids per chromosome and the...
alagy and Early Develapment Leberatory 2. Identify Homologous Chromosomes and Sister Chromatids in appropriate phases. What are homologous chromosomes? Are they present in all cells? If not, which cells lack homologous chromosomes? Are they present in all stages of mitosis? Are they present in all stages of Meiosis 1? Meiosis II? How do the terms haploid and diploid relate to the presence/absence of homologous chromosomes? What are sister chromatids? During what phase of the cell cycle do sister chromatids form?...
14. A chemical which is able to prevent chromatid separation is added to a cell culture. Which phase of mitosis would be most affected? anaphase prophase telophase G1 G2 15. In a cell which has started prophase of mitosis, there are times as many chromatids as the number of total chromosomes in that same original parent cell during G1. two three four six 17. Which of the following best describes the key process occurring with formation of bivalents (chiasma) during...
You are studying a cell which, before the S phase of the cell cycle, has 8 chromosomes and 1.2 picograms (1.2 × 1012 grams) of DNA. Complete the following table with the expected number of chromosomes, chromatids, and homologous pairs, and the amount of DNA in each area or pole of the spindle at each of the stages indicated. TYPED ANSWER ONLY Chromosomes Chromatids Homologous pairs DNA amount Prophase (Mitosis) Anaphase (Mitosis) Prophase I (Meiosis) Anaphase I (Meiosis) Anaphase II...
