Within double-stranded DNA, the nitrogenous bases on one strand pair with complementary bases along the other strand; in particular, A always pairs with T, and C always pairs with G. Then ...

DNA replication is the process by which the DNA molecule makes an exact copy of itself during cell division. The double helix unwinds, and each strand serves as a template for the synthesis of a new ...

Once the DNA is labeled at the 5′ end, a complementary tag can be added to the 3′ end by extension with a strand-displacing polymerase. PCR amplification with a single primer confirms tagging ...

In DNA, two complementary strands of nucleotides pair up through hydrogen bonds between the bases (A with T and G with C) to form the iconic double helix structure. RNA is usually single-stranded but ...

Original DNA template - DNA is a double helix made of two complementary strands. Each strand can be used as a template to create a new DNA molecule. Free DNA nucleotides – needed to form the new ...

Free RNA nucleotides form hydrogen bonds with the exposed DNA strand nucleotides by complementary base pairing to form a strand of mRNA: Note - RNA nucleotides contain the same bases as DNA ...

on one strand of the DNA and cytosine-thymine-guanine, or CTG, on the complementary strand—begin to repeat over and over, expanding to as many as 40 to 120 copies. The extended copies create ...
