Which of the following best describes the process of conjugation?
dna segments from broken-down prokaryotic cells are taken in and incorporated into the dna of living cells.
a bridgelike connection forms between two prokaryotic cells, through which genetic information is transferred.
changes in a cell’s dna sequences occur during replication, and those changes are passed on to daughter cells.
a virus takes in a segment of dna from one bacterial cell and inserts it into another bacterial cell.

What does the chemical formula c3h6o2 tell about a molecule of the compound it represents

How is ribosomal rna useful as a molecular clock? a. a large portion of the dna ring is not vital to structure or function, allowing it to accumulate neutral mutations. b. its rate of mutation increases over time as organisms continue to evolve and differentiate from each other. c. a slow mutation rate makes it useful for determining evolutionary relationships between ancient species. d. it is only found in select organisms, making it easier to compare relationships between species that have it.

Which best describes a benefit of using dna technology in medicine? a) medicine can be produced in mass quantities. b) medicine can be distributed at a reduced cost. c) medicines have fewer side effects. d) medicines are resistant to antibiotics.
