Question

A major difference between immunoglobulin heavy chains and light chains is that heavy chains contain _________.

Answer 1

The major difference between immunoglobulin heavy chains and light chains is that heavy chains contain a larger number of amino acid segments.

Step-by-step explanation:

One major difference between immunoglobulin heavy chains and light chains is that heavy chains contain a larger number of amino acid segments. Heavy chains consist of segments of variable (V) and constant (C) amino acid sequence composition. They have one variable domain (VH) and either three or four constant domains (CH¹, CH², CH³, and С₁4) depending on the antibody class.
