 Locating Genetic Information


Chromosomes are made up of genes. Each gene is a package of genetic information that gives the cell a particular instruction. The instruction is also called a code. Genes can code (have instructions) for several things.

  • A gene can code for a protein.
  • A gene can code for more than one protein.
  • A gene can code for structural RNAs.

Genes come in packages made up of 100 base pairs long all the way up to a few million base pairs. (More on base pairs later.) Genetic engineering is particularly interested in the genes that code for proteins, because this is where genetic traits and diseases come from.

Next, find out what makes up a gene.
