The three ways a bacerial DNA can be mapped are :
1. Bacterial conjugation
2. Mapping with Hfr strains
3. Recombination in bacterial crosses
Select ways in which genomic instability can arise. over proliferation of cells bacterial infections changes in chromosome structure changes in chromosome number mutations in DNA-repair genes Select ways in which genomic instability can arise. over proliferation of cells bacterial infections changes in chromosome structure changes in chromosome number mutations in DNA-repair genes
1. Explain how bacterial cloning can help increasing the amount of DNA (DNA amplification) and when it is implemented in science or in medicine. Use a diagram if needed.
Compare and contrast the 3 bacterial gene transfers with DNA recombination. Explain why these are not reproduction, and why they are important to bacterial species.
Semi-conservative DNA replication can be used by bacterial chromosome and plasmid both. a) True b) False
Match the following terms regarding bacterial transformation with the proper description 1 Bacterial cells that are able to take up DNA Click to select) 2. Bacters that can take up DNA naturally carry genes that encode these type of proteins (Click to select 3. An unnatural process in which the bacterial cells are forced to take up DNA Click to select 4. A natural process that has evolved in certain bacter in which they can take up extracellular DNA Click...
Describe five different ways by which antibiotics can disrupt bacterial cells and cell growth. Give an example of each .
3. (3 marks) Name and briefly describe the three different ways that chromatin can be modified to change gene expression.
Name the known DNA polymerases. Which DNA polymerases replicate DNA in the 5’-3’ direction? Which DNA polymerase is responsible for elongating the replicating strand? Which DNA polymerases function in DNA repair? Which DNA polymerase can remove either DNA or RNA nucleotides from the 5’ end of a nucleic acid strand?
List, and briefly discuss, (1-2 sentences max for each) the THREE different ways bacterial cells can exchange genetic information.
Assume that every time you copy DNA, whether it is bacterial DNA or human DNA, you have the same rate of mutation. If that is the case, explain why bacteria mutate to adapt to their environment much faster than humans.
