Answer:
The mitosis process includes only four phases of the event in mitotic cell division.
Explanation:
- Mitosis is the biological cell division cycle that produces tow daughter cell with equivalent number of chromosomes.
- In mitosis the nucleus divides, chromosome separates and moves to the opposite poles and forms two daughter cell at last.
- There are four phases in the mitosis cell division: prophase, metaphase, anaphase, and telophase repectively in the order.
- These four phases causes cytokinesis and occur in sequential order.
Answer options:
- extraction and observation of DNA
- identification of ribose and deoxyribose
- recognition of RNA as DNA’s messenger
- construction of an accurate DNA model
Answer:
- identification of ribose and deoxyribose
Explanation:
Phoebus Levene was an American biochemist who studied the structure of DNA and RNA. He was able to isolate the sugars (ribose and deoxyribose) from the nucleic acids, which are an important part of their structure.
He also determined how the nucleic acid components combine to form the nucleotides, the basic building blocks of nucleic acids, and how the nucleotides combine in chains to form the polymer.
