Answer:
These plants grow in very difficult environments. So, researching their genes may help botanists working in agricultural areas develop crops that can grow in inhospitable areas.

What is base pairing? (and Chargaff's rule)?
Answer:
A base pair (bp) is a fundamental unit of double-stranded nucleic acids consisting of two nucleobases bound to each other by hydrogen bonds. They form the building blocks of the DNA double helix and contribute to the folded structure of both DNA and RNA. The rules of base pairing (or nucleotide pairing) are: A with T: the purine adenine (A) always pairs with the pyrimidine thymine (T) C with G: the pyrimidine cytosine (C) always pairs with the purine guanine (G).
Explanation:
Chargaff's rules state that DNA from any species of any organism should have a 1:1 stoichiometric ratio of pyrimidine and purine bases and, more specifically, that the amount of guanine should be equal to cytosine and the amount of adenine should be equal to thymine. This pattern is found in both strands of the DNA.

A gene contains hundreds of chromosomes, which are composed of protein.
A gene is composed of DNA, but it has no relationship to a chromosome.
A gene contains hundreds of chromosomes, which are composed of DNA.
Answer:
A chromosome contains hundreds of genes, which are composed of DNA.
