Two cells from an animal’s heart are removed and studied. One cell has twice the amount of DNA as the other cell. Which statement is best explains why the second cell has twice the amount of DNA as the first? A The cell is in G1 and the extra DNA is needed now that the cell entering mitosis. B The cell is in G2 of interphase and now has all the DNA it needs function correctly. C The cell has just gone through S phase of interphase and will eventually divide in mitosis. D The cell is in G0 and no longer in a dividing state and has all the DNA needs to function correctly.

Genomic studies

Genomic studies (genomics) is the study of the whole genome of an organism. Using bioinformatics and high-performance computing, genomic researchers examined massive amounts of deoxyribonucleic acid (DNA)-sequence data to discover variations or mutations that affect drug response, health, or disease. Genomics is a much younger discipline than genetics, having only emerged in the last few decades as a result of technological advancements in DNA sequencing and computational biology.
