BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Messenger RNA (abbreviated mRNA) is a type of single-stranded RNA involved in protein synthesis. mRNA is made from a DNA template during the process of transcription.

Detailed explanation-2: -Transcription is the process by which DNA is copied (transcribed) to mRNA, which carries the information needed for protein synthesis.

Detailed explanation-3: -The majority of genes carried in a cell’s DNA specify the amino acid sequence of proteins; the RNA molecules that are copied from these genes (which ultimately direct the synthesis of proteins) are called messenger RNA (mRNA) molecules.

Detailed explanation-4: -RNA polymerase reads the unwound DNA strand and builds the mRNA molecule, using complementary base pairs. There is a brief time during this process when the newly formed RNA is bound to the unwound DNA. During this process, adenine (A) in the DNA binds to uracil (U) in the RNA.
