Learning Set 5 : Lesson 1 : Slide 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 2
A Recipe-Genome Analogy
A single recipe is like… A recipe book is like… Two copies of 23 recipe books is like…
A Gene:One set of instructions for how to make one protein.
A Chromosome: Thousands of sets of instructions for how to make thousands of proteins
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 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
Learning Set 5 : Lesson 1 : Slide 4
How similar are two DNA sequences?
Human DNA sequence: ATATTCCAAAChimp DNA sequence: ATATTAAAAA * * * * * * * *
How do you compare two DNA sequences?
