Total questions: 15
Worksheet time: 8mins
What is the purpose of protein synthesis?
To pass genes to offspring
To express our genes
To make new cells
To copy our DNA
What are the steps to protein synthesis?
transcription and translation
mitosis and meiosis
replication and division
photosynthesis and respiration
What is a codon?
the code used to make new DNA
the RNA that makes up tRNA
the RNA that makes up ribosomes
the 3 base "code" on mRNA that regulates which amino acids build the proteins
How many RNA nucleotide bases make up 1 codon?
1
2
3
4
What would the mRNA transcript be for the following DNA template? ATCGGATTCCGGAAT
TAGCCTAAGGCCTTA
UAGCCUAAGGCCUUA
What does the central dogma of biology describe?
Translation doesn't need transcription
Protein synthesis goes from DNA to RNA to Proteins
Transcription happens by itself
What happens during transcription?
DNA is made from other DNA
proteins are made from mRNA
mRNA is made from DNA
What happens during translation?
DNA is made from DNA
proteins are made from mRNA
mRNA is made from DNA
Which amino acid is coded for by the codon AUG?
Methionine (start)
Leucine
Tryptophan
Stop
Which amino acid is coded for by the codon UAU?
Leucine
Tryptophan
Glycine
Start
What are the differences between DNA and RNA?
DNA is a double helix, RNA is single stranded
The sugar is different
Uracil replaces thymine in RNA
All of the above
Where does transcription take place?
the nucleus
the stroma
the matrix
the cytoplasm
Where does translation take place?
the stroma
the nucleus
on the ribosome in the cytoplasm
the matrix
If an mRNA sequence has 12 nucleotide bases, how many amino acids would it code for?
2
4
6
8
What is the role of the tRNA in protein synthesis
it is what is transcribed from DNA
it contains the codons for amino acids
it transfers the correct amino acids to the mRNA
it makes ribosomes
