Raven Biology Chapter 28

Where does translation occur? 

• In the nucleus 
• On the ribosomes. 
• In the Golgi Bodies. 
• Outside the Cell. 

How does the mRNA leave the nucleus? 

• Through the nuclear pores (holes)
• Through the ribosome
• Through DNA ligase
• Backwards

What process is going on in this photo?

• Translation 
• Replication 
• All the above

What is the first step in protein synthesis? 

• mRNA leaves the nucleus and attaches to a ribosome
• tRNA molecules pair with mRNA codons as the mRNA slides along the ribosome 
• Amino acids are joined into a protein by an enzyme 
• DNA serves as a template to make mRNA inside the Nucleus 

What are the bases in mRNA? 

• A T C G
• A U G C
• A U T G

When using the codon chart, what type of RNA must be used? 

• mRNA
• tRNA
• rRNA
• mr.aRNA

Which form of RNA carries the code from DNA for producing Protein?

• rRNA
• mRNA
• tRNA
• iRNA

Ribosomes _________________________.

• have an anticodon and amino acid end
• serve as the location of transcription and are composed of rRNA and protein
• serve as the location of translation and are composed of rRNA and protein
• are located in the nucleus of the cell where translation takes place

DNA and RNA are made of what monomers?

• amino acids
• nucleotides
• monsaccharides
• lipids

Protein is made of what monomer component?

• amino acids
• nucleotides
• monosaccharides
• lipids
