Mendelian Genetics

Introns (non-coding regions) are removed, and exons (coding regions) are joined to form a mature mRNA strand. This process reduces the RNA length to 1200 nucleotides, ready for translation.

Restriction enzymes act at specific recognition sites or sequences on the double-stranded DNA. These sites are typically palindromic sequences, where the enzyme cuts the DNA to generate sticky or blunt ends. The specific term used for the nucleotide sequences recognised by a restriction endonuclease is recognition sequence.
