RNA-dependent DNA polymerases are a specialized class of polymerases that copy the sequence of an RNA strand into DNA.
Web22 de jun. de 2024 · RNA is smaller than DNA. RNA caps out at around 10,000 bases long, while DNA averages about 100 million. RNA can leave the nucleus. In fact, it does most of its work in the cytoplasm. There are several different types of RNA, each with different functions, but for the purposes of this article, we’re going to focus on messenger RNA … 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 …
