Answer: To eliminate bacteria that failed to take in the plasmid.
Explanation:
Research shows that plasmid DNA is only taken in by small percentage of bacteria in a large population.
Therefore, the need of growing transformed bacteria in the presence of ampicillin is very important. The main reason of this process is to kill off or eliminate bacteria that have failed to take in the plasmid, due to their possession of recombinant DNA plasmid pARA-R (an ampicillin resistance gene), that allows them to survive.
However, after completion of the aforementioned procedure, the bacteria that have been transformed will be able to take in the plasmid.
A nucleotide
Sugar + Phosphate + Nitrogenous base = Nucleotide
Answer:
Nucleus, chromosome, gene
Explanation:
The nucleus is the part of the cell where chromosomes are found. A human cell has 42 chromosomes. The chromosome have genes on them (made up of DNA strands – the strands are made of nucleotides). A gene is a sequence of nucleotides of the DNA that code for a functional protein.
Answer:
Angular unconformity represents the folding of an old sedimentary sequence, planing of the tilted strata by erosion, and the deposition of a young sedimentary sequence on the old truncated strata. ... Disconformity refers to an unconformity in which the beds above and below the surface are parallel.
