WebThere are chemical cross-links between the two strands in DNA, formed by pairs of bases held together by hydrogen bonds. They always pair up in a particular way, called complementary base... 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.
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. WebA DNA molecule is composed of two strands. Each strand is composed of nucleotides bonded together covalently between the phosphate group of one and the deoxyribose sugar of the next. From this backbone extend …
