Assignment Intro

What might these instructions be used for?

Just like a recipe is used to cook a meal or a blueprint is used to build a home, DNA contains instructions that specify an organisms traits (what they will look like)

REVIEW/DISCUSS

Are any two dogs alike? The dogs will share some traits in common with others BUT each has an overall combination of traits that is unique Variations in each DNA strand (the sequence of symbols) led to the inheritance of different traits

DNA Information in a DNA strand is grouped into small segments called genes (represented by your DNA strips) A strand of DNA is referred to as a chromosome (the dog had one chromosome containing 8 genes)
