Who is Louis Pasteur?
This gland, located at the base of the brain, is known as the "master gland" because it controls other endocrine glands.
What is the pituitary gland?
This technique amplifies specific DNA sequences by cycling through denaturation, annealing, and extension steps.
What is PCR (Polymerase Chain Reaction)?
This type of covalent bond links the 3' carbon of one nucleotide to the 5' carbon of another, forming the backbone of DNA and RNA.
