DNA, RNA, and Protein Synthesis

DNA replication results in two DNA molecules,

• each with two new strands.

• one with two new strands and the other with two original strands.

• each with one new strand and one original strand.

• each with two original strands.

Observe the diagram. #9 is pointing to

• a codon

• a nucleotide

• hydrogen bonds

• deoxyribose sugar

Observe the diagram. The sugar and phosphate backbone of a DNA strand is labeled by which numbers?

• 8 and 9

• 11 and 12

• 12 and 13

• 9 and 10
