Which statement accurately reflects the relationship between cell biology and molecular biology?
Which statement accurately reflects the relationship between cell biology and molecular biology?
- Cell biology focuses primarily on the genetic code, while molecular biology studies the larger structures within cells.
- Molecular biology is concerned with the evolutionary history of cells, whereas cell biology examines their current metabolic processes.
- Cell biology and molecular biology are essentially the same discipline, using different techniques to study the same phenomena.
- Molecular biology investigates the molecules that carry out cellular functions, while cell biology studies the broader context of cellular structures and processes. (correct)
