HKDSE Biology - Biomolecules (Protein and Nucleic acid)
Compulsory Part I Cells and Molecules of Life
Relate the significance of biomolecules (protein and nucleic acid) to life.
Biomolecules are elementary building blocks exist in organism and they assist the vital biological process for life.
Significance of protein and nucleic acid 👇🏻
Protein is biosynthesized from 20 amino acids which each of them consist of a carbon atom, hydrogen atom, amino group (-NH2), carboxyl group (-COOH) as well as a variable residual group (-R). Two main type of protein are fibrous protein and globular protein.
1. Fibrous protein
2. Globular protein
👆🏻This is the structure of long fibre like fibrous protein and spherical shape globular protein.
Nucleic acid 🧬
Nucleic acid is biosynthesized from nucleotide which consist of a five carbon sugar, a phosphate group as well as nitrogen containing bases (A, G, C, T, U). Two main type of nucleic acid are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
👆🏻This is the structure of DNA and RNA which are types of nucleic acid.
The details of DNA and RNA will be discussed in the up coming blog 📃 😉
In HKDSE Biology examination, the importance of protein and nucleic acid towards the functioning of the organisms will be asked ❗️ ❕
That's the end of this topic 👏🏻
