Detailed explanation-1: -Transcription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA). DNA safely and stably stores genetic material in the nuclei of cells as a reference, or template.
Detailed explanation-2: -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-3: -RNA molecules are produced by copying part of a nucleotide sequence of DNA into a complementary sequence in RNA. This process is called transcription. Transcription requires the enzyme RNA polymerase.
Detailed explanation-4: -This information is transferred to RNA via the process of transcription. After the completion of transcription, the information within the RNA is encoded to form proteins, and this occurs via the mechanism of translation, in which the genetic information of the DNA is finally translated to protein form.
