What is a gene?
Genes are the sequence of DNA that codes for a protein and this determines a trait. A gene is a unit of heredity which is transferred from a parent to offspring and is held to determine some characteristics of the offspring. Genes are part of a long molecule called the DNA, it is made up of sequences of bases on a DNA strand. Each sequence codes for specific protein. They are recipes to make specific proteins. Genes tell a cell how to function and what traits to express.

What is a genome?
A Genome is a set of chromosomes. Each genome contains all of the information needed to build and maintain an organism. A genome is simply the sum total of an organism's DNA. Genomes are a set of chromosomes in each cell of a multicellular organism. Genomes are a complete set of genes or genetic material present in a cell or organism.
