Answer: Transcription is the first step in gene expression. It involves copying a gene's DNA sequence to make an RNA molecule. Transcription is performed by enzymes called RNA polymerases, which link nucleotides to form an RNA strand (using a DNA strand as a template).
Explanation:
Before carbohydrates are absorbed, the enzymes sucrase,
maltase and lactase digest disaccharides into monosaccharides in the small
intestine. Sucrase breaks down sucrose into glucose and fructose, maltase
breaks down maltose into two glucose, and lactase breaks down lactose into
glucose and galactose.
