Why it is very difficult to classify proteins?
Due to the complexity of structure and diversity in their function, it is very difficult to classify proteins.
Classify proteins according to their structure.
- Fibrous proteins
- Globular proteins
Give the characters of fibrous proteins.
- They consist of molecules having one or more polypeptide chains in the joint form of fibrils. Secondary structure is most important in them.
- They are insoluble in water
- They are non-crystalline
- They are elastic in nature.
Where does DNA occur in cell?
DNA occurs in chromosomes, in the nuclei of the cells and in much lesser amounts in mitochondria and chloroplasts.
Where RNA is present in the cell?
RNA is present in the nucleolus, in the ribosomes, in the cytosol and in smaller amounts in other parts of the cells..
What are nucleic acids? Or Nucleic acids are polymers of units of which component?
The nucleic acids are polymers of units called nucleotides. DNA is made up of deoxyribonucleotides, while RNA is composed of ribonucleotides.
