A duplicate copy of all of the hereditary information contained in the nucleus of eukaryotic cells is made during what stage of the cell cycle?

S Phase

Explanation:

S phase is also known as DNA synthesis phase during which the Hereditary information or material is being copied to prepare for the cell division. Hereditary information is stored in DNA which is the part of chromosomes. So, the number of chromosomes doubled in S phase of the cell life cycle.

S phase of cell cycle.

A duplicate copy of all of the hereditary information contained in the nucleus of eukaryotic cells is made during S phase of the cell cycle.

Explanation:

Cell cycle consists of three phases :

G1 phase: In this phase, cell is rapidly growing and carrying out routine functions (it is the longest phase of all)

S phase (Synthesis phase): During this phase, DNA replicates from a single chromatid into a full chromosome(A duplicate copy of all of the hereditary information contained in the nucleus of eukaryotic cells is made) .

G2 PHASE: During this phase organelles replicate and chemicals needed for mitosis are produced and sent to proper locations within the cell.
