- Select TRANSCRIBE & TRANSLATE A GENE and WHAT MAKES A FIREFLY GLOW?
Your homework due on the block day is to finish the questions from the DNA From the Beginning web site: http://dnaftb.org/15/concept/
The questions are below, in case you don't have your sheet.
Questions from DNA from the Beginning Concepts 21 – 24.
#21. RNA is an intermediary between DNA and protein.
1. What is the "Central Dogma?"
2. What is the difference between transcription and translation of the DNA message?
3. From the PROBLEM section: How would you describe two types of genetic mutations? How do the mutations change the protein product?
#22. DNA words are three letters long.
4. How does a three-letter code make it possible to make 64 different combinations?
5. Why was it believed that it was necessary to have a three-letter code?
6. What is a codon?
7. From the PROBLEM section: Why can there be more then one possible mRNA sequence for a peptide sequence?
#23. A gene is a discrete sequence of DNA nucleotides.
8. How would you define a gene?
9. What is DNA sequencing?
10. From the PROBLEM section: How do you read an autoradiogram of a gene sequencing gel?
#24. The RNA message is sometimes edited.
11. What happens to mRNA when there is no binding region of DNA to match?
12. What is the difference between an intron and exon?
13. From the PROBLEM section: What causes a doublet to form in a gel sequence?
14. From the PROBLEM section: How can you detect the exon regions on an electron micrograph of a DNA/RNA hybrid?
