A friend of yours claims to have identified a gene that causes a human disease! Your friend says that they have sequenced the DN
sattari [20]

Answer: Point mutation is easily reversible, thus non-lethal

Explanation:

Point mutation is caused by exchange of a single nucleotide for another. These change is called

1) Transition (when a purine base substitute another purine base, or pyrimidine bases substitute each other)

2) Transversion (when a purine base substitute a pyrimidine base).

However, note that a point mutation can be easily reversed by another point mutation; so, the claim that a nucleotide difference in the Hsr12 gene caused the human disease is inaccurate

evablogger [386]

Prokaryotes divide by binary fission, a form of asexual reproduction in which a cell divides into two cells with identical genetic information.

Explanation:

Binary fission and mitosis can be viewed as the same principle of  asexual reproduction to give out two identical cells. However, the major difference between the two is that binary fission is to prokaryotes and mitosis is to eukaryotes. Remember that prokaryotes do not have a true nucleus (they have a nucleoid) hence binary fission does not involve the dividing of the nucleus. Mitosis does.

Sexual reproduction is responsible for creating variation in offspring especially due to the process of meiosis in gamete development and subsequent fertilization of two gametes from different parents.
