Question

A bacterial cell gives rise to two genetically identical daughter cells by a process known as no disjunction. Mitosis. meiosis. Fission. Fertilization. Which of the following would most likely result from a mutation in the ori gene of a bacterial cell? The cell would not be able to detect whether conditions were favourable for replication. The initiation of DNA replication would be hindered. Sister chromatics would not be separated. The cell would not be able to segregate DNA molecules. The cell could not undergo meiosis. A tissue in a mouse contains two types of cells: one that divides rapidly and one that divides more slowly. The most likely difference between these two cell types is that the slow-dividing cell type spends more time in phase. G1 g_2 G3 M S Replacing Arg in a histone with a neutral amino acid would make the histone_positively charged, and [ likely to bind to DNA. more; more more; less less; more less; less None of the above; this replacement would have no effect because Arg is a neutral amino acid. Which of the following does not occur during mitotic prometaphase? Disappearance of the nuclear envelope Initial movement of chromosomes toward the equatorial plate Adhesion of chromatics at the centromere Pairing of homologous chromosomes Disappearance of the nuclei Most zygotes are multicellular. diploid. animals.

Explanation / Answer

1. Mitosis- It is the process which produce identical daughter cells

2. Option -b. Initiation process will be hindered due to improper binding of DNA polymerase

3. It will spend time in G1 phase- Because it will get ready for synthesis phase in G1 phase

4. less ; less because it will be less positively charged and will decrease the binding of DNA

5. Pairing of homologous chromosomes - It occurs in meiosis not in mitosis

6. Diploid. - It is a diploid cell which initiates mitotic cell division to form multicellular organism
