Transcription and RNA Processing

ID #2127

Iím looking at lecture 16's slide 12 and it says that either strand can be used as the template for a given gene. Does this mean that both strands contribute to a given chromosome?


The slide does say that either strand can be used as a template for a given gene, but only one strand actually serves as the template. Remember that the DNA strands are complementary, not identical, so different information is contained on each strand. The position of the promoter of a given gene determines which strand actually serves as the template for transcription. Chromosomes are made up of double-stranded DNA, and both strands of DNA encode genes that can be transcribed into proteins.
