Question

UIC Cadar Tesllavom Select one: a. Can break down lactate to generate ATP via the electron transport chain. b. May carry out fermentation, substituting a molecule other than Oz as the terminal electron chain. O c. Must be strict anaerobes. d. May use fermentation to generate ATP, with alcohol released as a byproduct. Clear my choice Hereditary information is encoded in a single, circular DNA molecule in most prokaryotes. Which of the followi. bacterial chromosome? Select one: a. The bacterial chromosome has genes that control binary fission. b. Bacterial cells can replicate their DNA very rapidly under appropriate conditions The DNA of the bacterial chromosome is replicated prior to segregation. d. Bacterial cells utilize a mitotic spindle to segregate their replicated DNA

Answer 1

Bacterial cell bacterial cell utilise a mitotic spindle to segregate there replicated DNA

The last statement is incorrect because bacterial cell show cell division but it is amitotic, formation of spindle fibres does not take place.

First option is correct because bacteria undertake binary fission and divides it into two bacterial cells. The genes are located on the bacterial chromosome. The bacterial chromosome is linear or circular in shape and is double stranded in nature. It is enclosed in nucleoid.

Second statement is correct because the size of bacterial genome is very small and is not associated with any non coding region. Therefore it replicates rapidly in comparison to Eukaryotic DNA.

Third statement is correct because not only in bacteria but in eukaryotes also, before cell division DNA is replicated so that daughter cells receive an equal amount of DNA.
