The answer is number 3 because the species has to adjust rapidly to change their environment.
Answer:
Please find the explanation below
Explanation:
Deoxyribosenucleic acid, commonly called DNA is the stored form of genetic material in living cells. It contains the information needed by an organism to survive. A segment of the DNA that encodes the necessary information needed to produce a particular protein that determines a trait is called GENE.
The DNA consists of long polynucleotide chains, hence, due to Its length, it cannot git into the cell. The cell then devises a means by wrapping the long strands of DNA around certain proteins called HISTONES. This initially forms a NUCLEOSOME structure, then continuous wrapping around histones and condensation forms the visible CHROMOSOME structure.
Now, the CHROMOSOME contains the DNA molecule, which contains protein-coding segments called GENES. The information contained on the gene is used to produce a protein that is responsible for a particular TRAIT in the organism.
The structure of DNA is double helix which looks like twisted ladder. The sides of the DNA molecule, the rails of the ladder are composed of alternate phosphate and sugar molecules.
Is it not to store and transmit genetic info ?
Answer: I think it was Richard Nixon.
I'm not completely sure about it, but I hope this helps!! :)
