Nucleotide bases can be randomly replaced with different nucleotide bases to increase variation The nucleotide bases can also be used to provide the energy needed for reproduction. Nucleotide bases in one strand can only be paired with specific bases in the other strand. There are many different types of nucleotide bases that can be incorporated into DNA.

What happens to each strand of DNA after breaking the hydrogen bonds between the two strands? Group of answer choices Each strand grows to double its original length. Each strand winds back upon itself exactly two times. Each strand serves as a template for synthesis of a new strand. Each strand takes a spiral appearance that is twice as thick.
What is the significance of the complementarity of the two strands of DNA? It prevents mutations from occurring during replication. It allows for the recreation of one strand based on the other strand. It ensures that there are no errors when DNA is replicated.
Which of the following statements is true of double stranded DNA? The chains have a backbone of linked bases. Unless the DNA is circular, the 3'OH groups of each chain are at opposite ends of the molecule The planes of the bases lie parallel to the helix axis. The double stranded structure is stabilized only by hydrogen bonding,
