Use these images (and anything else you like) to construct your own zoomified understanding of genetics. Note that Prezi has maximum zoom-in and zoom-out limits, so you may need to draw a few things out of scale.

The Genetic Basis of
Cystic Fibrosis

46 Chromosomes
44 Autosomes
There are...
in a human cell.
These include:
&
2 sex chromosomes
arranged into 23 base pairs.
Cystic Fibrosis is associated with
a gene on base pair # . . .
A closer look at the
gene's of a CF carrier
would reveal ...
The genes that contain the instructions for the CFTR protein are found in this DNA
GENES
Ribosomes . .
... reading the RNA of a carrier ...
. . should produce
normal CFTR protein
However....
if 2 carriers reproduced ....
there is a 25% chance
their offspring would have ...

CF+, CF-

CF+, CF-
2 copies of the mutation

Ribosomes . .
... reading the RNA

. . produce defective
CFTR protein
3 base pairs in the DNA are missing
leading to Cystic Fibrosis
missing one crucial amino acid
