How dna strands are held together
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. … WebA DNA strand has a phosphate at the 5' end and a hydroxyl group at the 3' end. The two strands in a DNA molecule have the same 5' to 3' orientation. Complementary DNA strands are held together by hydrogen bonds between the bases. A DNA nucleotide consists of the sugar ribose, a phosphate, and a nitrogeneous base. Flag question: Question 15

WebApr 11, 2024 · DNA is made of two linked strands that wind around each other to resemble a twisted ladder — a shape known as a double helix. Each strand has a backbone made of alternating sugar (deoxyribose) and … WebSep 24, 2024 · The strands are held together by hydrogen bonds between bases on complementary strands. Hence like proteins, DNA has secondary structure but in this case, the hydrogen bonds are not within the backbone but between the "side chain" bases on opposing strands.
WebThe DNA bases pair together: A-T, T-A, G-C and C-G. DNA is arranged in a double helix structure. A gene is a short section of DNA that is the genetic code for a characteristic. WebThe two strands go in opposite directions, with the nitrogen-containing bases facing inward to make the steps or rungs of the staircase and the sugar-phosphate backbone making up the outside walls of the helix. The hydrogen bonds between the nitrogen bases keep the two strands of DNA together and help keep the DNA molecule stable and whole.
WebDNA bases : A and T, G and C. These can be either way around, but A always pairs with T and G with C. The base pairs are held together by weak chemical hydrogen bonds. The double-helix...
