Question 1 of 6
Question
The DNA double helix is composed of two single-stranded DNA molecules. Which of the following statements is accurate when considering how the two single-stranded DNA molecules interact with each other (interstrand) and how the nucleotides interact within the same strand (intrastrand)?
Correct.
Incorrect.
Question
Scientists traditionally illustrate a DNA sequence, such as that of the BRCA2 gene shown in the simulation, as a single strand, with the assumption that it is written:
Correct.
Incorrect.
Question
The DNA and RNA sequences resulting from DNA replication and RNA synthesis, respectively, of the DNA encoding amino acids 380–381 of BRCA2 (5’-AGTGAC-3’) are:
Correct.
Incorrect.
Question
R-loops are stable RNA-DNA hybrids that may form during transcription. They also have essential biological roles in initiation of DNA replication in mitochondria and prokaryotes. What characteristic of DNA and RNA molecules allows this type of interaction to occur?
Correct.
Incorrect.
Question
Which tertiary DNA structure has more nucleotide pairs per turn of DNA?
Correct.
Incorrect.
Question
An artificial way of separating the two strands of a DNA molecule is by using heat. High temperatures will denature the DNA double helix by breaking the hydrogen bonds between nucleotides. Which base-pair bond, respective to the rest, would need higher temperatures to denature?
