What base pairs with Adenine (A) in DNA?
Thymine (T) pairs with Adenine (A) through two hydrogen bonds.
What base pairs with Guanine (G) in DNA?
Cytosine (C) pairs with Guanine (G) through three hydrogen bonds.
What is the structure of DNA?
DNA has a double helix structure made up of repeating units called nucleotides.
What are the three components of a nucleotide?
Phosphate, Deoxyribose sugar, Nitrogenous base
What is the role of the phosphate group in DNA?
The phosphate group forms part of the DNA backbone, connecting to the next nucleotide.
What is the function of deoxyribose sugar in DNA?
Deoxyribose sugar is a five-carbon sugar that helps form the backbone of DNA, bonded to both the phosphate group and the nitrogenous base.
How do base pairs function in the DNA structure?
The base pairs form the "rungs" of the DNA ladder, while the phosphate and sugar groups form the "sides."
What is the orientation of the two strands of nucleotides in DNA?
The two strands run in opposite directions (antiparallel) and twist into a double helix.
