- 11. Multiple Choice
Why does DNA stay in the nucleus?
To protect it from becoming damaged.
It is lazy.
It is grounded.
It cannot move.
- 12. Multiple ChoiceWhich of the following would most correctly describe DNA?Permanent (should never break down)Temporary (breaks down after it is read)
- 13. Multiple ChoiceWhich of the following molecules holds the code for ONE gene at a time?DNARNA
- 14. Multiple ChoiceWHY must we use RNA if we already have genetic code in DNA?RNA is portable and can be read by the ribosomeRNA is more accurate than DNAThe cell needs a backup code and uses RNADNA and RNA can be used interchangeably
- 15. Multiple Choice
Why do we care so much about making proteins in our cells?
Almost everything in our cells is made of proteins
If a protein is made incorrectly it will not work
Proteins determine our physical traits
