Question

What are the three groups of structural genes of eukaryotes?

Answer 1

Eukaryotes:

1. Organisms whose cells have a well-defined nuclear membrane and all organelles are membrane-bound are called eukaryotes.
2. The cell which has a nuclear membrane around the nucleus is called a eukaryotic cell.
3. The chromosomes (composed of DNA and histone proteins) are located inside the nucleolus of the eukaryotic cell.

Structural genes of eukaryotes can be grouped based on their function:

1. Cellular genes: These are genes that are responsible for cellular functions like an ionic exchange, synthesis of the cell's membrane, etc.
2. Tissue level genes: These are tissue-specific genes that work towards the specific function of the tissue.
3. Organ system genes: These genes are responsible for the function of a particular organ. For instance, the cells constituting the thyroid gland are responsible for the release of thyroxin.
