Answer:
The correct sequence that represents the arrangement of structures containing genetic material, from the largest to the smallest size, is:
Chromosomes: These are the largest structures that contain genetic material. Chromosomes are made up of DNA and proteins and are visible under a microscope during cell division.
Genes: These are segments of DNA that contain instructions for making proteins. Genes are located on chromosomes and are the basic unit of inheritance.
DNA: This is the genetic material that carries the instructions for the development and function of all living organisms. DNA is a long, double-stranded molecule made up of nucleotides.
Nucleotides: These are the building blocks of DNA. Each nucleotide is made up of a sugar molecule, a phosphate group, and a nitrogenous base. There are four types of nitrogenous bases: adenine, thymine, cytosine, and guanine.
Base pairs: These are the complementary nitrogenous bases that pair up to form the rungs of the DNA ladder. Adenine pairs with thymine, and cytosine pairs with guanine. The sequence of base pairs determines the genetic code.
