Summary – Transcription vs Reverse transcription Transcription and reverse transcription are two processes which facilitate gene expression. Transcription is the first stage of gene expression. During transcription, a mRNA molecule is formed using a DNA template. The enzyme involved in this synthesis is RNA polymerase.

The initial step in gene expression is the transcription of the DNA molecule into an exact RNA copy. As already discussed, the basic unit of heredity, the gene, is a double stranded DNA molecule and the information in the gene is encoded in the sequence of nucleotides. The transfer

The DNA-dependent RNA polymerases have the following properties: 1. template dependent, requiring double-stranded DNA 2. do not require a primer; synthesis begins with a nucleoside triphosphate 3. require the four nucleoside triphosphates (ATP, GTP, CTP, and UTP) 4. copy (read) the template DNA strand in the 3' to 5' direction

A. TRANSCRIPTION- From DNA to mRNA: 1. RNA polymerase (enzyme) attaches at a specific location on DNA 2. The enzyme then causes the DNA strands to separate from one another and allow one of the DNA strands to be decoded 3. mRNA nucleotides are floating around in the nucleus find their complement on the DNA stand and bond together. This is ...

known as Transcription. RNA is chemically less stable than DNA and mRNA can be thought of as a temporary copy of DNA’s information. Transcription Translation Gene: DNA segment needed to make a protein Genes are typically 103 - 104 base pairs in size although they can be much larger. For example, the human dystrophin gene is 2 x 106 base pairs.
