Review foe Honors Bio Exam
Protein shape is determined by...
The type of cell producing the protein
The interaction of charge amino acids
The order of the nucleotides that make up the protein
The type of ribosome that produces the protein
As a result of DNA being retained within the nucleus, __________ molecules are required to carry the instructions for an individual protein to the cytoplasm.
Amino acid
TRNA
Ribosome
MRNA
Which of the following would NOT product the denaturation of proteins shown above?
Exposure of the protein to very high temperatures
Exposure of the protein to very high pH levels
Exposure of the protein to very low temperatures
Exposure of the protein to very low pH levels
How does a cell know to produce a specific type of protein?
Cells produce every protein coded in the DNA
Protein production is completely random in cells
Different types of ribosomes produce different types of proteins
Environmental signals indicate which genes to transcribe
Place the following steps of protein synthesis in the correct order: 1. The ribosome reaches a stop codon and releases the completed protein 2. The ribosome attaches to the mRNA moelcule 3. The tRNA molecules deliver specific amino acids that correspond to the mRNA sequence 4. The mRNA is transcribed in the nucleus 5. The mRNA migrates out of the nucleus to the cytoplasm
