Here's a breakdown:
* Polyploidy: This refers to the condition of having more than two sets of chromosomes in a cell. The prefix "poly-" indicates the presence of multiple sets of chromosomes.
* Polypeptide: This is a chain of multiple amino acids linked together by peptide bonds. The prefix "poly-" signifies the presence of many amino acids.
Essentially, "poly-" helps us understand that both polyploidy and polypeptide involve the existence of multiple components: chromosomes in polyploidy and amino acids in polypeptide.
