WorksheetsProtein Synthesis Review
Total questions: 10
Worksheet time: 6mins
Which process is happening in this image?
DNA is being replicated prior to cell division
DNA is being transcribed into mRNA
mRNA is being translated into amino acids
Peptide bonds are joining amino acids into a polypeptide chain
During transcription, the enzyme RNA polymerase reads the DNA strand and builds a strand of mRNA that will be used for protein synthesis. Where does transcription occur in the cell?
Nucleus
Cytoplasm
Both in the nucleus and cytoplasm
During translation, the ribosome reads the mRNA and uses tRNA to create a chain of specific amino acids in an exact order. Where does translation occur in the cell?
Nucleus
Cytoplasm
Both in the nucleus and cytoplasm
Transcribe the following DNA strand into mRNA.
TACGGTACTA
ATGCATGAT
AUGCCAUGAU
CGUAACGUCG
TACGGTACTA
Select the THREE choices that correctly describe RNA.
Single-stranded
Found in the nucleus and the cytoplasm
Has the base Uracil (U) instead of Thymine (T)
Contains all of the organism's genes
Which process is occurring in this image?
Translation of mRNA into amino acids and proteins
Transcription of DNA into mRNA
Replication of the DNA prior to cell division
Immune cells defending against a virus
Match each type of RNA with their function.
tRNA
Carries amino acids to the ribosome
rRNA
Contains the codes used for translation
mRNA
Helps make the structure of the ribosome
Use the codon chart to translate the following mRNA sequence into amino acids.
AUA CGA CCU UUA
Val - Arg - Leu - Leu
Met - Gln - Leu - Phe
Ile - Arg - Pro - Leu
What is the main outcome of transcription?

mRNA is read to make a chain of amino acids
A strand of mRNA is formed
What is the main outcome of translation?
The strand of DNA is copied
mRNA is read to make a chain of amino acids
A strand of mRNA is formed
