Answer #1

Answer;

The winning sperm will reach the female egg first and it will try to get into the sperm. During these period it will undergo some process for the sake of penetrating the outer wall of female egg, This process would be referred as the acrosome reaction. During this period the winning sperm will produce certain kind of enzymes like Hyaluronidase and acrosin which consume outer shell membrane and have a way to get into the egg cell. By these way the winning sperm will enter the cell and deliver its chromosome for reproductive process.

A sperm that fertilizes an egg carries its mitochondria into the egg’s cytoplasm. However, male-derived mitochondrial nucleoids have completely disappeared within 60 min after fertilization. This experimental observation is most likely due to ________________. a) The “bottle-neck” inheritance of mitochondria.' b) The degradation of mitochondrial proteins. c) The degradation of mitochondrial DNA. d) The dilution of male-derived mitochondria in the egg’s cytoplasm. e) The incompatibility of male and female mitochondria. I chose answer c) The degradation of mitochondrial DNA but...

We discussed the endosome system that viruses sometimes use to get their genetic material into the host cytoplasm. A. Imagine an endosome that maintains a pH of 5 under normal conditions when no hydroxychloroquine is present. Explain how an endocytic pump could use ATP to create such an acidic pH. B.Now imagine that hydroxychloroquine is suddenly present in the endosome. Explain the process that will happen to the hyroxychloroquine, the endosome pH, and the endocytic pump?

7)  Select the true statements about how bacteria can get new genetic material.  Circle all that apply. Conjugation can occur only between bacteria of the same species. In transformation, bacteria can pick up pieces of bacterial DNA from their surroundings. It is necessary for viruses to be lysogenic for restricted transduction to occur. In transduction, bacterial genes end up in viral capsids. Bacterial conjugation can use pili, which act as pseudopods, engulfing genes from another bacterium to incorporate them into the cell’s...

Most organisms carry their hereditary genetic information as DNA. However, some viruses use RNA instead. The HIV virus has RNA, but its genetic information is found in host DNA. How does this happen? a. An enzyme reverses the usual process, producing DNA from the viral RNA. b. The viral RNA goes through translation in the host cell. c. The viral RNA is actually a variant of DNA. d. Viral RNA attaches to the host’s chromosomes.
