Antibiotic used include kenamycin, ampicillin and tetracycline. This is useful to determine if and which bacteria took up the plasmid as they were supposed to during the process of recombination. Host bacteria are normally killed by these antibiotics. If the recombinant plasmids were taken up by the bacteria, plasmid may have contained a DNA gene for resisting the effects of one or more antibiotics. Host bacteria are placed in a growth medium containing an antibiotic to which they have a resistant gene in their recombinant plasmid DNA survivor. If they havent taken the plasmid they die.
It can't look like a line because that would mean animals evolve in orderly steps
First they need to go through interphase which is the phase of the cell copies it’s dna in preparation for mitosis.
Steps:
I-interphase
P-prophase
M-metaphase
A-anaphase
T-telophase
Answer:
proximate
Explanation:
In evolutionary medicine, it is widely recognized that diseases have both proximate and evolutionary explanations that enable us to understand how natural selection may lead to the disease state.
The questions raised under this idea are the following:
- How is the mechanism leading to disease
- Which is the ontogeny of the mechanism
- Which is the selective advantage of the disease state
- What is the evolutionary phylogenetics of the mechanism
