What is the structural feature that allows dna to replicate? a. dna molecules have the same number of purines and pyrimidines. b. the nitrogenous bases are located on the inside of the double helix. c. the strands of the double helix are complementary. d. twisting of the molecule to form an α-helixe. three-component structure of the nucleotides?

c. the strands of the double helix are complementary.

Explanation:

DNA replication is a process by which the double stranded DNA molecule get separated into two strands. These two stranded are separately copied by the cell machinery into two new DNA molecules from a single DNA molecule.Each complementary strand act as a template strand for the production of the new DNA molecule.

volcanoes (an event in the geosphere) release a large amount of particulate matter into the atmosphere. these particles serve as nuclei for the formation of water droplets (hydrosphere). rainfall (hydrosphere) often increases following an eruption, stimulating plant growth (biosphere).

this is true, assuming that the allele is completely recessive and incomplete dominance is not a factor.
