Replication
Replication is production of exact copy of DNA and it is highly accurate to maintain the information coded. A antibiotic resistance is accured by a cell through transformation, conjugation and transduction but not by replication

Please classify each statement as describing transformation, conjugation, or transduction in bacteria. Bacteria can acquire plasmids from outside the cell. A bacterium that contains an F plasmid connects to a recipient bacterium that lacks an F plasmid with an appendage called a pilus, through which the plasmid is transferred. Some bacterial DNA fragments may be included when new phage particles are assembled. A cell can be treated to make it competent to take up DNA from its environment. When a...

QUESTION 5 Which of the following is false? Select all the false choices. Types of horizontal gene transfer in bacteria include; conjugation, transformation, and transduction Translation takes place on ribosomes in the nucleus. Exposing bacteria to UV radiation can lead to induced mutations. Categories of mutation include point mutation, missense mutation and nonsense mutation. Three nucleotides code for three amino acids which is referred to as a codon. QUESTION 6 Which of the following pertain only to the lagging strand...

Antibiotic resistance can be transferred from one bacterial cell to another by conjugation. C. Interrupted conjugation results in the production of Hfr strains. D. Plasmids do not have to integrate into the host cell chromosome in order to be replicated. E. The order of gene transfer...
