What type of structure does dna have when unwrapped from chromosome protein structures?

Double helix structure

Explanation:

The DNA is composed of two strands which are linked together by hydrogen bond. The two strands are twisted around each other to form a ladder-like, double helix structure.

The structure of the DNA was proposed by Watson and Crick after series of research about the nature and structure of the DNA.

answer: after carbon dioxide enters the leaf through stomata it moves into the mesophyll cells where photosynthesis occurs and glucose is constructed. respiration occurs when glucose (sugar produced during photosynthesis) combines with oxygen to produce useable cellular energy.

explanation:

nucleic acid molecules are incredibly complex, containing the code that guarantees the four different nucleotide units comprise dna, the nucleic acid of interest to the genealogist. and one of four nitrogen-containing molecules called nucleotides
