Answer: One strand of DNA binds to another via base complementarity.
Explanation:
The two strands of the DNA double helix are connected through nucleotides. There are hydrogen bonds between the nitrogenous bases. Each nucleotide has a sugar, nitrogenous base and phosphate group. The phosphate group and sugar forms the backbone of the DNA double helix. The nitrogenous base form pairing with each other via base complementarity. Purines are adenine and guanine and pyrimidine are cytosine and thymine these are nitrogenous bases. The adenine bonded with thymine via two hydrogen bonds and cytosine with guanine with three hydrogen bonds. These nitrogenous bases help in replication process.
The two strands of DNA are actually connected by hydrogen bonds (H-bonds) between the nitrogenous bases.
There are 2 hydrogen bonds between adenine and thymine, and 3 hydrogen bonds between cytosine and guanine.
Why are sugar-phosphate and nitrogenous bases important to DNA molecules?The sugar-phosphate backbone is a significant component of DNA's double helix structure.
The structure of DNA is tied to its function. The pairing of the nitrogenous bases that are connected to the sugar-phosphate backbone play a key role in the ability of DNA to store and transfer genetic information.
Thus, base complementary is the reason.

What chemical compound is responsible for the rotten egg smell that is
typical of seal farts?
Hydrogen disulphide
Hydrogen monoxide
Hydrogen peroxide
Hydrogen chloride
Answer:
Hydrogen disulfide
Explanation:
Hydrogen disulfide , which is responsible for the rotten-egg scent, is toxic rather than simply smelly, if inhaled at concentrations above 700 parts per million.
It can be present at very low concentrations well below those considered to induce health effects. The scent of sulfide hydrogen does not affect your well-being.
Answer:
Hydrogen monoxide
Explanation:
It is very toxic to smell in farts
