|
Ribosomes translate mRNA strands differently depending on the type of cell they are in

Detailed explanation-1: -The genome of a cell contains in its DNA sequence the information to make many thousands of different protein and RNA molecules. A cell typically expresses only a fraction of its genes, and the different types of cells in multicellular organisms arise because different sets of genes are expressed.
Detailed explanation-2: -How might the DNA-RNA-protein pathway affect cellular differentiation? For example, cells in the interior of the body may be signaled by genes to become either muscle or connective tissues, while other cells on the exterior of the body will be signaled to become epithelial cells.
Detailed explanation-3: -However, two different cells of the same type may also have different gene expression patterns depending on their environment and internal state. Broadly speaking, we can say that a cell’s gene expression pattern is determined by information from both inside and outside the cell.
