TAKSObjeti!e " The student will demonstrate an understanding ofliving systems and the environment.
TEKS Siene Cone#ts 6 A, B, & C
The student knows the structures and functions of nucleic acids in the
mechanisms of genetics. The student is expected to
(A) describe components of deoxyribonucleic acid (DNA), andillustrate how information for specifying traits of an organism
is carried in the DNA
(!) explain replication, transcription, and translation using models
of DNA and ribonucleic acid ("NA)
(#) identify and illustrate how changes in DNA cause mutations
and e$aluate the significance of these changes

DNA 'xperiment for 6arents
/e ha$e been looking at the structure and function of DNA. Now, your student
is to demonstrate the extraction and discuss with you what they ha$e learned.
'xamples of a DNA source= peas, spinach, chicken, li$er, onions, broccoli,banana
1ere>s the fun part. 6ut into a bender=
5our DNA source (about *++ m3 or about *?@ of a cup)
A large pinch of table salt (*? teaspoon)Twice as much cold water as the DNA source (B++ m3 or about B?@ cup)
!lend on high for *C seconds.
6our your thin soupE through a strainer into another container (like a
measuring cup). 1ow much soupE do you ha$e9 Add about *? that amount of li:uid
detergent (about B tablespoons) and swirl to mix. 3et the mixture sit for C
