WebBase pairing. the 5' end (said as "5 prime end") at the phosphate end. the 3' end (said as "3 prime end") at the deoxyribose end. WebTo make a DNA molecule you need: nitrogenous bases—there are four of these: adenine (A), thymine (T), cytosine (C), guanine (G) carbon sugar molecules phosphate molecules If you take one of the four nitrogenous bases and put it together with a sugar molecule and a phosphate molecule, you get a nucleotide base.

WebFor example, a chemical reaction called deamination can convert a cytosine base into uracil, a base typically found only in RNA. During DNA replication, uracil will pair with adenine rather than guanine (as it would if the base was still cytosine), so an uncorrected cytosine-to … WebSo, with DNA, you have 2 base pairs, right? adenine and thymine (AT), as well as guanine and cytosine (GC) And, DNA hase 2 sides. So, does the pairing matter? Let's say we unwind the DNA, and then hold it strait up. Does it matter if the left side has Adenine vs Thymine? (So, mirroring it (not the orientation of the compound, just the location.

WebJan 19, 2024 · DNA bases pair up with each other, A with T and C with G, to form units called base pairs. Each base is also attached to a sugar molecule and a phosphate molecule. Together, a base, sugar, and phosphate are called a nucleotide. Nucleotides are arranged in two long strands that form a spiral called a double helix.
