How are dna strands antiparallel

WebAs DNA polymerases can only extend a DNA strand in a 5′ to 3′ direction, different mechanisms are used to copy the antiparallel strands of the double helix. In this way, the base on the old strand dictates which base appears on the new strand, and the cell ends up with a perfect copy of its DNA. Web12 de set. de 2024 · Does double stranded DNA consist of two antiparallel strands? Doubled-stranded DNA consists of two antiparallel strands, meaning that one strand is oriented in the 5′ to 3′ direction, while the other is oriented in the 3′ to 5′ direction. Asymmetrical spacing of the backbones of the DNA double helix generates major and …
