A double-stranded piece of alien nucleic acid has been isolated. Each individual strand of the nucleic acid is 160 nucleotides l

ong; for a total of 320 nucleotides in the isolated piece of nucleic acid. An initial analysis shows that of the 320 nucleotides, 95 contain the base uracil.1. How many nucleotides containing the base isoAdenine (iA) would be found in the isolated piece of double-stranded nucleic acid?a. 0b. 95c. 190d. 225e. cannot be determined2. How many nucleotides in the piece of alien DNA would contain the base adenine?a. 40b. 70c. 95d. 140e. cannot be determined

Answer:

95 isoadenine bases;  adenine bases cannot be determined

Explanation:

In Alien DNA;

  • iA  complementary with U
  • iT  complementary with A
  • bG complementary with iC
  1. So if there were 95 nucleotide that contain the uracil then there should also be 95 isoadenine.
  2. Adenine binds with isothymine in alien DNA and there are no information of  isothymine or other bG/iC bases is given, so we cannot determine the adenine bases.

Which statement belongs in the region marked X? (image attached)

Answer options:

  • Is the longest stage
  • DNA is copied
  • The number of nuclei doubles
  • The number of cells doubles

Answer:

  • The number of cells doubles

Explanation:

Cytokinesis describes the splitting of the cytoplasm after mitosis. During interphase, the DNA is replicated. During mitosis, the DNA condenses into chromosomes, and the chromosomes are aligned and separated to opposite ends of the cell. During cytokinesis, the cell separates into two daughter cells.
