'''Bold text'''vnmb,In [[molecular biology]], two [[nucleotide]]s on opposite [[complementarity (molecular biology)|complementary]] [[DNA]] or [[RNA]] strands that are connected via [[hydrogen bond]]s are called a '''base pair''' (often abbreviated bp). As DNA is usually double-stranded, the number of base pairs in the dsDNA strand equals the number of nucleotides in one of the strands. In DNA, [[adenine]] and [[thymine]], as well as [[guanine]] and [[cytosine]], can be a base pair. In RNA, [[thymine]] is replaced by [[uracil]].

The following abbreviations are commonly used to describe the length of a DNA/RNA molecule:

* kbp = kilo base pairs = 1,000 bpb

* Mbp = mega base pairs = 1,000,000 bp

* Gbp = giga base pairs = 1,000,000,000 bp
