What are the three parts that make up a RNA nucleotide?
What are the three differences between DNA and RNA?
If a DNA chain had the following sequence, CCGTAATAGCAT, what RNA nucleotides would attach to this
sequence?
What is mRNA stand for and what does it do?

What is a codon?
If a mRNA sequence had the following nucleotides: AAGGUCAGACGGUGA, how many codons are there?
What is the start codon?
What is Translation?
Where does Translation occur?
Where in the cell does transcription occur?
Where in the cell does translation occur?
When does translation begin?
What brings amino acids to the ribosome?
How many different amino acids can a tRNA carry?
What are the three unpaired bases at the bottom of a tRNA called?
What type of bond forms between amino acids?
What do the codons on mRNA specify?
What are the three main steps of protein synthesis?
Put the following terms in order how they would happen. mRNA, DNA, protein, ribosome
What instructions are found in genes?
How can cells that have the same DNA produce different proteins?
Compare and contrast (what is similar and different) the following terms:
Transcription
Translation
33. Compare and contrast(what is similar and different) the following terms:
DNA
RNA
For the statements below, write in the correct term. Some statements can have more than one answer.
mRNA
tRNA
DNA
34. Brings amino acids to the ribosome
35. Is made in the nucleus but moves to the cytoplasm.
36. Is made by RNA polymerase
37. Has the anticodon at the bottom.
38. Has the nucleotides Adenine, Guanine and Cytosine
39. Has codons on it
40. Ribosomes attach to this first to start translation.
41. Has the nucleotide Uracil
42. Is replicated by DNA Polymeras
