Both Hook and vanLeeuwenhoek helped to create the basis of cell theory by determining that all living things are made of cells.
Answer: The statement is false
Explanation:
It is a false statement because both DNA and RNA could consists of a double-stranded helix of sugars, phosphate groups, and nitrogenous bases.
The major differences however, is that thymine is found only in DNA, while uracil is found only in RNA molecules.
Cells are divided into two main classes, initially defined by whether they contain a nucleus. Prokaryotic cells (bacteria) lack a nuclear envelope; eukaryotic cells have a nucleus in which the genetic material is separated from the cytoplasm. Prokaryotic cells are generally smaller and simpler than eukaryotic cells; in addition to the absence of a nucleus, their genomes are less complex and they do not contain cytoplasmic organelles or a cytoskeleton (Table 1.1). In spite of these differences, the same basic molecular mechanisms govern the lives of both prokaryotes and eukaryotes, indicating that all present-day cells are descended from a single primordial ancestor.
