What Is Chromosome
This section provides a quick introduction of DNA/RNA base pairs and sequence pairs. A base pair is pair of two complementary nucleobases linked by hydrogen bonds. A sequence pair is a pair of two complementary sections of DNA/RNA sequence with their nucleobases form base pairs.
What Is Chromosome? - A Chromosome is a long DNA double helix wrapped around histone proteins into a condensed 3-dimensional structure.
The process of wrapping a DNA double helix can be described as:
The diagram below illustrates how a DNA double helix structure is wrapped and packaged into a chromosome (source: researchgate.net):
