Nucleotides can be radiolabeled before they are incorporated into newly forming dna and can be assayed to track their incorporation. in a pulse–chase experiment, a student–faculty research team introduced labeled thymine (t) nucleotides into a culture of dividing human cells. after a short time, they added large amounts of unlabeled t nucleotides. in which cell cycle phase would the labeled t nucleotides become incorporated into the dna?

The S phase

Explanation:

The cell cycle is divided into two major phases:

The interphase is further sub-divided into 4 phases:

The labeled T nucleotides will become incorporated into the cell's DNA during the DNA synthesis/replication phase of the cell cycle. At this phases, the double helix DNA unzips and each strand serves as a template for the synthesis of new strands. Replication fork forms and nucleotides are added to the growing chain of newly synthesized strands.

The correct answer is S phase.

In the interphase (taking into account that cell cycle is divided into two parts), t nucleotides become incorporated into the DNA

Explanation:

primary succession occurs in essentially lifeless areas regions in which the soil is incapable of sustaining life as a result of such factors as lava flows, newly formed sand dunes, or rocks left from a retreating glacier. secondary succession occurs
