Question

Answer all of the following questions.

Use the following information as the basis for answering all questions: A diploid eukaryotic organism has 3 unique chromosomes. Chromosome I is a metacentric chromosome, chromosome II is a telocentric chromosome, and Chromosome III is a submetacentric chromosome.

1. How many total chromosomes do somatic cells of this organism have in G1 of cell cycle?

2. How many total chromatids do somatic cells of this organism have in G1 of cell cycle?

3. How many total chromosomes do the somatic cells of this organism have in G2 of cell cycle?

4. How many total chromatids do the somatic cells of this organism have in G2 of cell cycle?

5.Viruses are living organisms, because they contain DNA and RNA.        A) TRUE          B) FALSE

6.The field of genetics includes the study of cellular processes including transcription and translation. A) TRUE    B) FALSE

7. Sequencing of organisms’ DNA has in many cases resulted in their original taxonomic reclassification based upon anatomical structure.     A) TRUE     B) FALSE

8.The # of chromosomes per cell never changes at any point during mitotic cell division A) True     B) False

9.In a diploid organism, __________line up at the metaphase plate during mitosis, ____________ line up at the metaphase plate during Meiosis I, and _________ line up at the metaphase plate during Meiosis II

Explanation / Answer

1. As the organjsm is diploid and the n=3, the total number of chromosomes in G1 = 6 chromosomes.

2. As DANA replication occurs in S phase in G1 phase each chromosome has only one chromatid.

3. In G2 phase each chromsome has two chromatids because of DNA replication in S phase, as these replicated chromatids bound to centromere, they are considered as same chromsomes. So, the number of chromosomes in G2 somatic cell is 6.

4. In G2 phase each chromsome has two chromatids because of DNA replication in S phase, as these replicated chromatids bound to centromere, they are considered as same chromsomes. So, the number of chromatids in G2 somatic cell is 6 * 2 = 12.

5. The answer is B) False. Because they dont show any metabolic activities. They act as a living thing when they are in host and they act as a non living things when they are out side of the host.
