According to Figure 20.1, which of the following statements about the first human genome sequencing project or the depicted DNA sequencing technique are correct?

  • A: The first human genome sequence was completed in 2003.
  • B: The depicted technique determines nucleotide sequence by detecting electrical current changes as DNA passes through a pore.
  • C: The cost of the first human genome sequence was approximately $1 billion.
  • D: The first human genome sequencing project took 10 years to complete.
  • E: The time and cost for genome sequencing have increased since the first project.

Explanation

According to the caption of Figure 20.1, the first human genome sequence was completed in 2003, cost $1 billion, and took 13 years. The depicted technique uses electrical current changes as DNA passes through a pore to determine nucleotide sequence. It also states that time and cost have been greatly reduced since the first project.
