Could you draw three molecules of water correctly, including the hydrogen bonds between
the molecules? - correct answer-
Deletion mutations? - correct answer-Deletion: Removal of one or more nucleotides from a
DNA sequence
Does a substitution mutation always change the amino acid sequence of the protein? -
correct answer-Has no affect at all
Does the place in the DNA sequence where the extra nucleotides are inserted matter? Why?
- correct answer-Yes because it causes it to have a frame shift which gives it different
codons
How about an insertion mutation? How about a deletion mutation? Why or why not? - correct
answer-Yes because it causes frame shift

characteristics of a living thing? - correct answer-Can create tumors
How did model building contribute to understanding DNA's structure? - correct answer-It
helped them understand the different bonds
, How did the structure of DNA give scientists insight into its function? - correct answer-It
helped them relate the different nucleotides with each other and differentiate between the
different bonds (ionic, covalent and hydrogen bond)
How did X-Ray crystallography contribute to understanding DNA's structure? - correct
answer-it helped them discover that the DNA structure was a double helix which helped
