1. How many genes do we have/need?
25,000 from Mom
25,000 from Dad
50,000 genes!
Learning Set 5 : Lesson 1 : Slide 1

2. A Recipe-Genome Analogy
A single recipe is like…
A recipe book is like…
Two copies of 23 recipe books is like…
A Chromosome:
Thousands of sets of instructions for how to make thousands of proteins
A Gene:
One set of instructions for how to make one protein.
Our Genome:
ALL of the sets of instructions for how to make ALL the proteins we need
ALL (gene, chromosome, genome) are written in same the DNA alphabet!!!
Learning Set 5: Lesson 1 : Slide 2

3. A Recipe-Genome Analogy
In order for scientists to find a specific gene, they need to know which “book” to look in,
and which “page” to turn to.
Genome
Chromosome
Gene
