If mature eukaryotic MRNA is hybridized with its corresponding genomic DNA template strand and visualized by electron microscopy, two types of structures are seen: RNA:DNA double-stranded heteroduplexes and single stranded DNA loop structures, as shown in the diagrams below. What do you think these single stranded DNA loops represent?

Genome annotation

The technique of linking biological information to genome sequences is termed genome annotation. Gene annotation is the method of identifying gene locations and coding sections. It helps us understand what these genes are doing in the body through establishing structural characteristics and linking them to the actions of various proteins.
