D. Biology. In forensics, they use DNA-related evidence, and DNA relates to biology.
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.
Answer:
Amylase and protease enzymes act on daal eaten at lunch.
Explanation:
Daal is the Indian name of pulses. Pulses contains both protein and carbohydrates in large amount and our body cannot absorb these nutrients due to bigger size. For the absorption of these nutrients, they can be broken down into simpler substances with the help of enzymes. Amylase enzyme helps in the break down of carbohydrate while protease enzyme is responsible for the break down of protein.
