What is a chromosome?

• a threadlike structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes.

• a substance produced by a living organism which acts as a catalyst to bring about a specific biochemical reaction.

• an organism that lives in or on an organism of another species (its host) and benefits by deriving nutrients at the other's expense.

• a group of living organisms consisting of similar individuals capable of exchanging genes or interbreeding
