What is a sense strand (or coding strand)?

Posted June 22, 2020


A sense strand, or coding strand, is the DNA strand within double-stranded DNA that carries the translatable code in the 5’ to 3’ direction. Its complementary strand is called antisense strand, which does not carry the translatable code and serves as template during transcription. The sense strand of DNA has the same sequence as the mRNA that contains the codon sequences to build proteins, except that thymine, instead of uracil, takes its place in the sense strand of DNA.
