Question

Each cell must produce only a subset of the genes that are being expressed. This subset is what differentiates one cell from another. For example, cancer cells must be expressing one subset of genes when compared to normal cells. Photosynthetic cells in a leaf are expressing different genes from root cells. A 'Northern blot' is used for

Answer 1

The correct answer is : Detection of specific RNA sequences

Step-by-step explanation:

This method is used to see and analyze a sample of RNA from a particular tissue with the purpose of measuring the RNA expression of particular genes. It also permits a person to observe cellular control over structure and function. This procedure requires the isolation of RNA from tissue samples from cultured cells.
