Protein Synthesis

Put the following steps of DNA Replication in order: 
1) DNA Helicase splits the DNA into single strands
2) DNA Polymerase attaches complimentary free nucleotides
3) DNA Helicase binds to DNA
4) DNA Polymerase Proofreads its work
5) DNA Polymerase binds all of the free nucleotides together

• 2, 1, 3, 5, 4
• 3, 1, 2, 4, 5
• 3, 1, 4, 5, 2
• 3, 2, 5, 1, 4

Transcription takes place in the 

• cytoplasm
• chloroplast
• nucleus
• mitochondria

Translation takes place in the 

• ribosome
• chloroplast
• nucleus
• mitochondria

This cannot leave the nucleus

• DNA
• RNA
• Both

Which is the mRNA molecule that would be transcribed from this DNA template:
TGGCAAGTACGT

• ACCGTTCATGCA
• UGGCAAGUACGU
• UCCGUUCUUGCU
• ACCGUUCAUGCA

Carries the genetic code to the ribosome

• mRNA
• tRNA
• rRNA
• DNA

The genetic code carries

• molecules through the cell membrane
• ATP across the cytoplasm
• instructions for translating information into proteins
• lysosomes around to kill bacteris

Which best describes how the traits of an organism are determined by the DNA in their cells?

• DNA provides the energy need for cellular processes
• DNA is copied to mRNA, which controls cellular functions
• DNA codes for proteins which allow an organism to grow and function
• DNA unzips and each strand codes for a different amino acid

What amino acid is represented by the codon UUA?

• Phenylalanine
• Tyrosine
• Leucine
• Stop codon

What is the correct amino acid sequence for the mRNA code AUGCCAGUAUGA

• Met-Pro-Ala-Val
• Met-Pro-Val
• Tyr-Gly-His
• Tyr-Gly-Arg-His
