Answer:
3' OH ( hydroxyl group).
Explanation:
DNA is present as the genetic material in almost all the living organisms except in case of some viruses only. DNA is made of the polymers of the nucleotides.
The phosphodiester bond is present between the two nucleotide chains. The phosphodiester is a covalent bond formed in which the phosphate group of nucleotide is involved with the hydroxyl group of the sugar and a small molecule like water is removed during the process.
Thus, the correct answer is 3' OH ( hydroxyl group).

All of the consumers would be affected, and be forced to adapt. Since the amount of grass has decreased, the primary consumer would struggle to survive, and most likely, die out. Since the primary consumer has probably died out, the secondary would either die, or be forced to adapt to the situation, or change habitats ( applies to the rest in the food chain / web).

Answer:
This statement is best described by the option B. The recombinant DNA produced by the combination of a vector and gene of interest in the E.coli which produces multiple copies of this recombinant DNA along with the chromosomal DNA and expresses the gene.
Explanation:
In genetic engineering, the gene of interest is combined with a vector e.g. plasmid and inserted into the most suitable carrier for these recombinants. This carrier acts as the manufacturing unit for the gene of interest as it produces multiple copies when it replicates in a short period of time. E.coli is considered to be one of the best manufacturing units in the field of genetic engineering as it has a very flexible replication time.
