DNA Replication is when a DNA strand is used to create another DNA strand, while DNA transcription is used to create a complementary RNA strand.

In essence both processes work in the same way, but their products and some of their tools differ. For example:

  1. Replication uses the enzyme DNA Polymerase while transcription uses RNA Polymerase.
  2. Replication results in a complementary DNA strand, while replication a complementary mRNA strand.

As you study both concepts, you will find that they are similar in about every other aspect.

Here are two Crash Course Videos that help grasp these concepts:
