Question
In prokaryotic cells, DNA replication occurs in the Select one: a. Cytoplasm b. Cell membrane c. Ribosome d. Nucleus e. Stroma Proteins in the cell serve as checkpoints during the cell cycle to ensure that the cell has successfully completed a particular phase of the cell cycle. What can result if the checkpoint proteins are defective in the cell cycle? Select one: a. Cell death b. Cancer c. New cells with too many chromosomes d. Cell free for all e. A and C The specific region on a chromosome where chromatids are attached to each other is called Select one: a. allele b. centromere c. homologue d. locus e. telomere What are telomeres? Select one: a. A specific location of a gene on a chromosome b. An attachment site for microtubules that move chromosomes during cell division c. A protective cap on the end of chromosomes that keep genes intact during DNA replication d. A sex chromosome e. A very condensed piece of DNA What is the result of mitosis? Select one: a. Four genetically identical cells b. Two genetically identical cells c. Four genetically different cells d. Two genetically different cells e. One cell with twice as much DNA as the original cellExplanation / Answer
6) Prokaryotes does not contain nucleus. Therefore, the DNA replication in prokaryotes occurs in cytoplasm. There is only one origin of replication or replicon. The enzyme, DNA gyrase is essential for prokaryotic DNA replication. Therefore, the answer for this question is option a (cytoplasm).
