Question
Chapter 26.4, Problem 3CC
Summary Introduction
To explain: How a gene could have different functions in different tissues within an organism.
Concept introduction:
Living things are composed of specialized cells, for different functions. However, each cell has same genetic makeup, but the expressions of genes are tissue-specific. There are many regulatory mechanisms that control the expression of a gene. The genetic information in genes is transcribed as messenger RNA (mRNA). The transcribed mRNAs contain non-coding sequences called introns. RNA-splicing is the process that removes the introns present in the mRNA before the instruction for protein synthesis.
