Chromatin make h bonds
WebA nucleotide is the basic structural unit and building block for DNA. These building blocks are hooked together to form a chain of DNA. A nucleotide is composed of 3 parts: The sugar and phosphate group make up the … WebThe two strands of the DNA molecule are held together by hydrogen bonds between the complementary bases. An enzyme called "helicase" "unzips" the strands, i.e. breaks down the hydrogen bonds and holds the strands apart temporarily until new complementary strands are produced by other enzymes.

WebFeb 25, 2024 · Understanding the mechanisms that trigger chromatin compaction, its patterns, and the factors they depend on, is a fundamental and still open question in Biology. Chromatin compacts and reinforces DNA and is a stable but dynamic structure, to make DNA accessible to proteins. In recent years, computational advances have provided …
WebDNA is a polymer of the four nucleotides A, C, G, and T, which are joined through a backbone of alternating phosphate and deoxyribose sugar residues. These nitrogen-containing bases occur in complementary pairs … WebA DNA molecule consists of two polynucleotide strands that form a double helix. The strands are held together by hydrogen bonds between the nitrogen‑containing bases. …
