Detailed explanation-1: -It consists of two major steps: transcription and translation. Together, transcription and translation are known as gene expression. During the process of transcription, the information stored in a gene’s DNA is passed to a similar molecule called RNA (ribonucleic acid) in the cell nucleus.
Detailed explanation-2: -The enzymes that perform transcription are called RNA polymerases. Like the DNA polymerase that catalyzes DNA replication (discussed in Chapter 5), RNA polymerases catalyze the formation of the phosphodiester bonds that link the nucleotides together to form a linear chain.
Detailed explanation-3: -Ribosome. A ribosome is the cellular machinery responsible for making proteins. There are many ribosomes in each cell, each made up of two subunits.
