Why Do We Need Single Stranded DNA? All organisms must replicate their DNA when cells divide. During DNA replication, an enzyme called helicase unwinds the dsDNA and opens a replication fork where the two strands of parental DNA are separated. Single-strand binding proteins bind to the two strands to prevent them from reannealing. Is single
Does DNA Polymerase Need A Template Strand To Copy From? They always need a template. They can only add nucleotides to the 3′ end of a DNA strand. They can’t start making a DNA chain from scratch, but require a pre-existing chain or short stretch of nucleotides called a primer. Which polymerase does not require
What Are The 4 Basic Components Of The Sanger Sequencing Reaction? The DNA sample is divided into four separate sequencing reactions, containing all four of the standard deoxynucleotides (dATP, dGTP, dCTP and dTTP) and the DNA polymerase. What components are required for Sanger sequencing? A DNA polymerase enzyme. A primer, which is a short piece
