How dna strands are held together

WebApr 10, 2024 · DNA consists of two strands that wind around each other like a twisted ladder. Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups. Attached to each sugar is one of … WebThe DNA of an individual can be found in almost all of their cells. Purines and pyrimidines are nitrogenous bases found in DNA. A hydrogen bond connects purine with a pyrimidine. Two hydrogen bonds connect adenine to thymine, while three hydrogen bonds connect guanine and cytosine.

WebIn a double helix structure, the strands of DNA run antiparallel, meaning the 5’ end of one DNA strand is parallel with the 3’ end of the other DNA strand. The nucleotides forming each DNA strand are connected by noncovalent bonds, called hydrogen bonds. 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.
