Science - Lesson #4: DNA to RNA

EOU Exam on Thursday, May 1st

Science

Lesson #4:

DNa to RNA - Transcription

Learning Intention:

Students will be able to compare, contrast and synthesize why/how transcription occurs.

Success Criteria:

I am successful when I can...

1. Compare and contrast DNA from RNA

2. Transfer my knowledge of DNA structure to RNA.

3. Predict what would happen if mistakes are made during transcription and the effect it may have on protein synthesis.

Agenda:

Part 1: Replication Warm-Up

Part 2: Vocabulary

Part 3: Differences Between DNA and RNA

Part 4: Video

Part 5: Codon Chart

Reminders:

Practice Regents #3 due April 21st

Quiz, Tuesday April 1st.

Part 1:

1) Transcription: Process where the DNA in the nucleus is copied into a message called RNA.

2) mRNA: Stands for messenger RNA. Carries genetic code to ribosomes. Key to protein creation.

Part 3:

2 Box Induction

(5 min)

View the images below and discuss with your group:

1) What are some similarities between the two boxes

2) What are some differences?

Part 4:

How does DNA go from RNA to Proteins?

(5 min)

Frayer model - surface, deep, deep, transfer

Key Points

DNA is trapped in the nucleus. It creates a message, called RNA, which can leave the nucleus.
