What bond holds the nucleotides on the same strand of dna together

answer:

explanation:

the nucleotides in a base pair are complementary which means their shape allows them to bond together with hydrogen bonds. the a-t pair forms two hydrogen bonds. the c-g pair forms three. the hydrogen bonding between complementary bases holds the two strands of dna together.

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.

cells spend most of their time in interphase
