DNA is a chain of nucleotides bonded together. On that chain there are particular portions of it that the sequence of the nucleotide codes for particular proteins; this is known as a gene. In eukaryotric cells, DNA is coiled around proteins such as histones to form chromatids which when two join at the centre by a centromere to form a chromosome.

Answer:
She has been dead for 5 days.
DNA and RNA both contain a cyclic nitrogenous base, a posphate group and a five-carbon sugar. These are the base units of nucleotides which make up nucleic acids. DNA contains the nitrogenous bases; adenine, thymine, cytosine and guanine wheresas RNA contains the bases; adenine, thymine, cytosine and urasil. DNA codes for the nucleotides in an RNA molecule, whereas DNA codes for the amino acid sequence in a protein
Answer:
The moon's gravity pulls at the Earth, causing predictable rises and falls in sea levels known as tides.
The strong tug from the Moon influences the tides, animal life particularly in the intertidal zone would have to adapt fast.
