3 codons that are translated into 3 polypeptides
9 nucleotides that are translated into 9 amino acids
Carlita was hired for a job as a laboratory assistant. She will work for a professor of molecular biology who wants to make new discoveries about genes, DNA, RNA, and their functions. Carlita’s work will MOST LIKELY contribute to which of these specific research goals?
Identifying the molecule that makes up genes
Describing the role of RNA polymerase in RNA synthesis
Determining the links between genes and the traits they influence
Identifying the types of nucleotides that make up RNA
Velma is developing a computer model of translation. Her instructor points out that the model does not include ribosomes or ribosomal RNA. If the model is accurate in other ways, how does the absence of ribosomes and ribosomal RNA affect it?
Certain amino acids would be missing from the polypeptides.
The polypeptides would be much longer than normal.
Amino acids would be joined together in an incorrect order.
Amino acids would not join together, and no polypeptides would form.
A polypeptide is a sequence of ____________________ held together by a ______________ bond.
amino acids; peptide
fatty acids; ionic
proteins; hydrogen
fatty acids; covalent

Met
GLu
Ala
Phe
