20. What is happening in #19?
For 21- 30, Choose DNA, RNA or Both:
21. Contains deoxyribose sugar
22. Can be found in the nucleus of the cell
23. Has three different types
24. Contains ribose sugar
25. Contains Uracil (U) as one of its bases
26. Is double-stranded
27. Contains Thymine (T) as one of its bases
28. Is involved (used or made) during transcription
29. Is involved (used or made) during translation
30. Contains Adenine (A) as one of its bases
For 31- 38, Choose DNA Replication, Tanscription, Translation, Both Replication and
Transcription, or Both Transcription and Translation:
31. Occurs in the nucleus
32. The two stages of protein synthesis
33. Process where mRNA is “decoded” into a chain of
amino acids
34. Process where DNA is copied into two identical
molecules of DNA
35. This process involves tRNA carrying amino acids to
ribosomes
36. Process where DNA is used to make mRNA
37. Process that occurs during the S phase of the cell
cycle
38. Process that occurs at ribosomes
39. Given the following strand of DNA, construct the complimentary mRNA molecule that would
be made during transcription:
DNA strand: TAC – GCA - TGG – AAA – GGG – CGG – ACT
mRNA strand: ____ - _____ - _____ - _____ - _____ - _____ - _____
Next, use the decoder chart below to write the corresponding amino acids that would be coded for
by the mRNA that you created:
Amino acids: ______ - _______ - _______ - _______ - _______ - _______ - _____
40. If there were a mutation in the original DNA sequence above where the first G was deleted,
what would happen to the protein that would ultimately be made?
