Chromosomes are made of DNA and proteins called histones. Genes are segments of DNA that encode the order of amino acids in proteins.

Answer:

genes are found on DNA and DNA strands forms chromosomes

Explanation:

DNA consists of sequence of nitrogen bases (A,T,C and G) these bases are linked together by phosphodiester bonds forming the backbone of the DNA strand, the DNA is a molecule that carries the genetic instructions which are genes. genes are the basic physical and functional unit of heredity, they are the instructions on DNA which make protein. DNA strands containing these genetic instructions (genes) are packed in the form of chromosomes, the long strands of DNA are wrapped around protein complexes called nucleosomes which consists of protein called histones, the DNA in chromosomes serves as the source for transcription, during cell cycle the number of chromosomes are replicated and every cell gets a copy of the chromosomeshttps://en.wikipedia.org/wiki/File:Chromosome_DNA_Genesvg
