Comparing DNA Replication and Transcription

3' CTGGCTAC5'           5' GACCGATG 3'    3'CUGGCUAC 5'

Explanation:

Some of the sequence of DNA given is in 3' to 5' direction, mRNA sequence is also given.

The DNA is double stranded helix which replicates by semi conservative mode. The two strands unwind to act as a template for other strands. In transcription the 3' to 5' strand acts as a template because RNA synthesis takes place in 5' to 3' direction. mRNA is single strand. It has nucleotides in it from which 3 base pairs acts as a code for amino acid.

The following table shows DNA strand having complementary sequaence and mRNA synthesized.

The reaction shown in the question is an inversion reaction.

The conversion of maltose to glucose is an inversion reaction. An inversion reaction is said to have occurred when the atoms and groups in a molecule are rearranged. The numbers and type of each atom in a molecule remains the same.

The reaction; Maltose +A -> Glucose + B is an example of an inversion reaction. The missing items A and B are both the catalyst maltase.
