create a hypothesis to explain how changes to the amino acid sequence in the MC1R protein could affect its function

Which statement is true of the translocation phase of elongation during protein synthesis?   a. The empty tRNA moves to the A site of the ribosomal complex.   b. The empty tRNA moves to the T site of the ribosomal complex.   c. The dipeptide moves from the A site to the P site of the ribosomal complex.   d. The dipeptide moves from the P site to the A site of the ribosomal complex.

Vasopressin and oxytocin are examples of peptide molecules with more than one function. Provide examples of these functions and then speculate as to why organisms use the same molecules in seemingly different processes.

Give an example of how the change in primary sequence can change the function of a protein.

Construct an explanation based on evidence for how the structure of DNA determines the structure of proteins which carry out the essential functions of life through systems of specialized cells.

Use the model to answer the following questions. 1. Which of the arrows (1 or 2) represents transcription and which represents translation? How do you know? Ribosome 2. Label the amino acid chain in the model. Why did you pick this structure to represent your amino acid chain? 3. Label everywhere you see MRNA in the model. Explain at least 2 ways you know this structure represents MRNA?

Explain why the statement is true. In the course of evolution of protein synthesis in the eukaryotic cell, the ability to perform Dehydration Synthesis to form the peptide bonds between amino acids is associated with: the rough endoplasmic reticulum
