WebJul 30, 2024 · How does DNA polymerase know in what order to add nucleotides? Specific base pairing in DNA is the key to copying the DNA: if you know the sequence of one strand, you can use base pairing rules to build the other strand. Bases form pairs (base pairs) in a very specific way. Figure 5. DNA chemical structure. WebBases form pairs (base pairs) in a very specific way. Figure 8 shows how A (adenine) pairs with T (thymine) and G (guanine) pairs with C (cytosine). It is important to remember that this binding is specific: T pairs with A, but not with C. The molecular recognition occurs because of the ability of bases to form specific hydrogen bonds: atoms ...

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. One strand is complementary to the other strand, which means that a base on one strand is paired with a base on the opposite strand. WebBecause of the sizes and functional groups of the bases, base pairing is highly specific: A can only pair with T, and G can only pair with C, as shown below. This means that the two strands of a DNA double helix have a very predictable relationship to each other. biowood perthWebEukaryotic genomes are much more complex and larger than prokaryotic genomes and are typically composed of multiple linear chromosomes ( Table 11.2 ). The human genome, for example, has 3 billion base pairs per haploid set of chromosomes, and 6 billion base pairs are inserted during replication. biowood installation
