Key Concepts

Transcription

Transcription is the process where RNA polymerase synthesizes an RNA molecule using a DNA strand as a template. This is the first step in gene expression and ensures that the information stored in DNA is converted into a form (mRNA) that can be used in protein synthesis.

Base Pairing Rules

Base pairing rules dictate how nucleotides on the DNA template strand pair with complementary RNA nucleotides during transcription. Specifically, adenine (A) pairs with uracil (U) in RNA, while cytosine (C) pairs with guanine (G), and thymine (T) on the DNA pairs with adenine (A) in RNA.

Template DNA

The template DNA refers to the single strand of the double helix that is read by RNA polymerase to build the mRNA. This strand carries the necessary information by providing a sequence that is complementary to the mRNA sequence to be synthesized.

5' to 3' Directionality

The 5' to 3' directionality refers to the orientation in which nucleic acids are synthesized. RNA polymerase adds new nucleotides to the 3' end of the growing mRNA chain, resulting in a strand with a free 5' end at the beginning and a free 3' end at the end of transcription.
