What causes hemolytic disease of the newborn (HDN)? HDN most frequently occurs when an Rh negative mother has a baby with an Rh positive father. When the baby's Rh factor is positive, like the father's, problems can develop if the baby's red blood cells cross to the Rh negative mother.

Answer:
From the diagram X = <u>base pairs</u>
Explanation:
Genetic information stored within DNA is used for growth, reproduction, and cell repair. DNA, deoxyribonucleic acids, are long-chain, helical macromolecules made of specific sequences of covalently bonded monomers called nucleotides.
Nucleotides comprise:
- a 5-Carbon deoxyribose sugar,
- one nitrogenous base (adenine, guanine thymine, and cytosine)
- and a phosphate group.
Nitrogenous bases cause nucleotides to form hydrogen bonds with other nucleotides as base-pairs. The four types of bases each make the nucleotides Thymine and Cytosine (pyrimidine bases) along with Guanine, and Adenine, (purine bases). In base-pair formation, Adenine forms double bonds with Thymine, and cytosine forms triple bonds with guanine.
