Lesson: Transcription
Unit 8: DNA, Protein Synthesis, and Genetic Technology
Date: __________________
Biology I
Objectives:
 SWBAT explain that DNA contains the instructions to make proteins, and that the DNA  RNA 
protein pathway is called the central dogma of biology.
 SWBAT compare and contrast the properties of DNA and RNA
 SWBAT define the process of transcription
Do Now
1. Place the following steps of DNA replication in ORDER: ____________________________
I.
DNA unzips
II.
The sugar-phosphate backbone in the new strands is joined with covalent bonds
III.
Two new strands result, both of which are identical to the original strand.
IV.
Free nucleotides are added to the original strands by DNA polymerase
2. Imagine the original strand of DNA is white, and the new nucleotides are red. Which of the following
represents two strands after DNA replication?

The Steps of Transcription
1) An enzyme ___________________ the
DNA molecule by _____________ the
hydrogen bonds.
2. An enzyme called ______________
______________________ connects
______________________________ to
their complementary bases.
3. When mRNA is done forming, it
____________________, and DNA
______________________________.
>> Check for Understanding
Using the top strand of DNA as the template, show what a complementary mRNA molecule would look like:
5’ CCGTATTTA 3’
3’ GGCATAAAT 5’

translated into proteins, cytosine, nucleic acid, made up of nucleotides, introns removed
RNA
DNA
Venn Diagram: Comparing Transcription and DNA replication
Use the following terms: Results in two identical strands, RNA polymerase DNA unzipped,
complementary bases paired, creates single-stranded molecule, DNA polymerase,
original DNA comes back together
