Detailed explanation-1: -In the simplest sense, expressing a gene means manufacturing its corresponding protein, and this multilayered process has two major steps. 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-2: -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-3: -The Central Dogma of Molecular Biology states that DNA makes RNA makes proteins (Figure 1). The process by which DNA is copied to RNA is called transcription, and that by which RNA is used to produce proteins is called translation.

Detailed explanation-4: -Transcription. The process of copying DNA information into the structure of the mRNA molecule is called transcription.

Detailed explanation-5: -Introns and exons are part of the genomic code. Genes contain both introns and exons but introns are spliced while forming the messenger RNA.
