Different types of topoisomerases have different functions and these include accessing DNA, recombination process strand breakage, removing DNA supercoils, chromosome condensation and detangling intertwined DNA. All form... More »

The function of RNA polymerase II is to synthesize mRNA using a DNA strand as a template, explains UC Davis BioWiki. The process, by which an mRNA strand is constructed from a DNA strand, is called transcription, and the... More »

Many enzymes are involved in DNA replication, including DNA helicase, DNA polymerase, topoisomerase, DNA gyrase, DNA ligase, primase and telomerase. Replication is a complex process with many steps, all of which require ... More »

Lagging strand synthesis is the creation of a complementary DNA strand on the lagging strand of DNA. When DNA is being replicated, the DNA molecule unzips a little at a time, with one strand labeled the "leading strand,"... More »

Chromatin is a strand of DNA wrapped around a protein, and is a building block of all chromosomes. The chromosome is the structure in which DNA is stored in cells. More »

Semi-conservative replication is the process of creating two copies of DNA, with both copies consisting of an original and a new strand. This process creates enough genetic information to divide among two cells when cell... More »

A palindromic sequence is a strand of DNA in which the sequence of nucleotides on one rung is repeated, albeit in reverse, on its complementary rung. If the sequence on one side of the double helix reads "GACTG," the com... More »
