Explanation:
Detailed explanation-1: -Template strand is the DNA strand off which the mRNA is synthesized.
Detailed explanation-2: -In the first step, the information in DNA is transferred to a messenger RNA (mRNA) molecule by way of a process called transcription.
Detailed explanation-3: -RNA polymerase synthesizes an RNA transcript complementary to the DNA template strand in the 5’ to 3’ direction. It moves forward along the template strand in the 3’ to 5’ direction, opening the DNA double helix as it goes.
Detailed explanation-4: -The type of RNA that contains the information for making a protein is called messenger RNA (mRNA) because it carries the information, or message, from the DNA out of the nucleus into the cytoplasm.
