Exam 3: Proteins

The process of protein synthesis is also called:

The enzyme that bonds two amino acids together in protein synthesis is:

Protein structure characterized by the combination of different proteins that all together are required for protein function is which level of protein structure?

A codon consists of a sequence of how many nucleotides?

Specialized proteins that bind to the large ribosomal subunit and protect the hydrophobic regions of growing polypeptides are called:

Alpha helices and beta-pleated sheets are what level of protein structure?

What chemical group is found at the beginning of peptide chains?

The chemical nature of alanine, leucine, phenylalanine, and tryptophan is described as:

What enzymes are important for faithful translation of genetic information from RNA to protein?

In early experiments, a polymer of uracil, UUUUUUUU…, translated into a peptide comprising only phenylalanine amino acids. What did this observation demonstrate?

The collection of proteins produced by a genome is called the:

The start codon for synthesis of most proteins is:

The set of nucleotides in mRNA that encode one amino acid is called a(n):
