Protein Synthesis

A sugar, a phosphate group, and a nitrogen base form the building blocks of which organic compound?

• carbohydrates
• nucleic acids
• lipids
• proteins

Which of the following is the template for the production of RNA within a cell?

• DNA
• protein
• ATO
• carbohydrate

which process is shown?

• diffusion
• repiration
• recombination
• translation

When an extra base is inserted into the DNA sequence of a gene, the protein doesn't work. Which explains why?

• the base increases rate of translation
• the base causes DNA to be transcribed in opposite direction
• the inserted base causes the codons in the sequence to be incorrect for the desired protein
• the base signals enzymes to translate DNA rather than RNA
