Answer:
True
Explanation:
DNA ligases are enzymes required for replication, repair, and recombination of DNA molecules. The DNA ligase repairs the break in the DNA molecule by the formation of a phosphodiester bond.
The bacterial genome consists of a circular DNA molecule, thereby laboratories use these enzymes to create recombinant DNA molecules
Answer:
At least 17 PCR cycles or 16 PCR cycles
Explanation:
As we know -
In one chain of heating and cooling of polymerase chain reaction (PCR), the strands of DNA gets doubled.
The general mathematical representation of this is
where "n" is the number of PCR cycles.
It is given that DNA strands to be produced is 16 times the original quantity of DNA.
So the PCR cycle must be carried out at least 17 times in order to have DNA strand not less than 16 times the original quantity of DNA
I think it would be 25% likely hood
Explanation:
The chemicals are contaminant in the ground water system and they can inflict serious health hazards on humans when water is sourced from such polluted ground water system.
- Consuming contaminated water can lead to cholera and diarrhea.
- It makes ground water toxic and poisonous.
- Drinking contaminated ground water can lead to the introduction of heavy metals in the body.
- Chemical wastes containing radioactive materials can damage body tissues.
- They render ground water unsafe for drinking ans usage.
