Heavy strand（重定向自Light strand）
Circular molecules of DNA, such as plasmids and typical mitochondrial genomes, consist of two strands of DNA called the heavy strand (or H-strand) and the light strand (or L-strand). The two strands have different masses due to different proportions of heavier nucleotides. While this difference is not known to have any functional significance, it can be used in the laboratory to segregate the strands of denatured DNA, and hence to analyze the strands separately. |
