TRANSCRIPTION (DNA -) mRNA) Use the DNA code provided to make an m Which nitrogen base CAN'T you use during transcription? __

## Step 1<br />Transcription is a process in which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA). This process is crucial in the production of proteins.<br /><br />## Step 2<br />During transcription, the DNA sequence is copied into mRNA. The DNA sequence is made up of four types of nitrogenous bases: Adenine (A), Thymine (T), Guanine (G), and Cytosine (C).<br /><br />## Step 3<br />However, in the mRNA, Thymine (T) is not used. Instead, Uracil (U) is used in its place.
