Answer:
mutations to homologous genetic loci
Explanation:
Phylogenetic tree, which is a diagrammatic representation of evolutionary relationship among organisms, can be constructed from evidence from molecular systematic with regard to the similarities in the mutations to homologous genes.
Homologous genes are genes that are inherited by two species from a common ancestor having similar DNA sequence. An example of homologous gene is Orthologous gene, which is said to have be brought about by speciation.
Answer: Put the answer in your own words.
The defining characteristic of prokaryotes is that they lack a membrane-enclosed nucleus. The single chromosome, usually circular, is tightly wound and compact. The region of the cytoplasm containing the chromosome is called the nucleoid.
Answer:
D. just before or just after the separation of sister chromatids
Explanation:
The mitotic spindle is a structure of the eukaryotic cell cytoskeleton involved in mitosis. Their function is to separate the sister chromatids during cell division so that they are included in the daughter cells. It consists of longitudinally aligned microtubule bundles that together have an ellipsoid-like shape.
For this reason, we can state that if a drug that prevents disassembly of the mitotic spindle paralyzes the cell cycle immediately before or shortly after separation of the sister chromatids.
Answer:
cytokinesis HOPE THIS HELPS :}
Explanation:
The vesicles inside the cell are mostly propelled by the microtubules in the cytoskeleton of the cell. Colchicine is a potent microtubule inhibitor (other microtubule inhibitors are Paclitaxel and Vincristine) that will disrupt the locomotive mechanisms of the vesicles leading to stopping or slowing down of movement of the vesicles.
