A group of cells is assayed for DNA content immediately following mitosis (G1) and is found to have an average of 8 picograms of DNA per nucleus. How many picograms would be found at the end of S, and the end of G2 for this cell type

16 pg at the end of S

16 pg at the end of G2

Explanation:

A cell has 8 pg of DNA per nucleus in G1.

During S phase the DNA replicates, so every nucleus will contain double the normal amount of DNA that was present in G1. Therefore, at the end of S each nucleus would have 16 pg of DNA.

During G2 the cell continues growing and preparing for mitosis, but DNA content does not change: there are still 16 pg per nucleus.

what following? you said which of the following. but there is no be more specific.

carbohydrates: (starches and sugars) composed of carbon, hydrogen, and oxygen.

lipids: (fats, oils, and waxes) are made of carbon and hydrogen atoms.

nucleic acids: contain hydrogen, oxygen, nitrogen, carbon, and phosphorus. they are polymers of nucleotides. a nucleotide has three parts, a 5-carbon sugar, a phosphate     (-po⬇️4) group, and a nitrogenous base.

proteins: made up of nitrogen, carbon, hydrogen, and oxygen. they are polymers of amino acids.
