Learning Objectives

SW review DNA replication

SW learn the base-pairing rules for RNA

Multiple Choice

The rules of DNA pairing states that Adenine (A) always pairs up with

• Thymine
• Cytosine
• Adenine
• Guanine

Multiple Choice

The rules of DNA pairing states that Cytosine (C) always pairs up with

• Thymine
• Cytosine
• Adenine
• Guanine

Multiple Choice

Which sequence of DNA bases would pair with this partial strand
CAT TCA CTG

• ATG TGA CAG
• TAC ACT GTC
• GTA AGT GAC
• CAT TCA CTG

Multiple Choice

Name this structure

• double helix
• nucelotide
• twisted ladder
• hydrogen bond

Multiple Choice

Replicate the following strand of DNA:

AATCATGGA

• AATCATGGA

• TTAGTACCT

• UUAGUACCU

• GGATAUCUA

Multiple Choice

Replicate the following strand of DNA:

AATCATGGA

• AATCATGGA

• TTAGTACCT

• UUAGUACCU

• GGATAUCUA

Transcription

This is the process of reading DNA to create mRNA

RNA bases

RNA has four bases: Cytosine (C), Guanine (G), Adenine (A), and Uracil (U)

Unlike DNA, RNA does not have a Thymine - it has a Uracil instead!

A=U

G=C

Transcription

The process of transcription: DNA (Green) and mRNA (Red)

DNA: ATA GCA TAT

mRNA: UAU CGU AUA
