AP Biology Questions and Answers (Graded A) A mutation in the gene coding, for a single-polypeptide enzyme results in the substitution of the amino acid serine, which has a polar R group, by the amino acid phenylalanine, which has a non-polar R group. When researchers test the catalysis of the normal enzyme and the mutated enzyme, they find that the mutated enzyme has a much lower activity than the normal enzyme does. Which of the following most likely explains how the amino acid substitution ...

In humans, exposure to ultraviolet light can result in a darkening of the skin. What kind of property is this? response to the environment What is the scientific term for a group of interacting individuals of the same type, living in the same area at the same time? population Which series of terms is in the sequence of bio...

AP Biology Unit 2.1 AP Exam review Questions and Answers What is the structure and function of the ribosome? A ribosome has two subparts, one large subunit and one small subunit. A ribosome functions to synthesize proteins using messenger RNA How does the structure of a ribosome aid in its function? Because ribosomes are made of ribosomal RNA it aids in its ability to read mRNA. because of its structure it can take in the mRNA and read it to synthesize proteins What are the three ty...

AP Biology Unit 2 Cell Structure Exam Review Questions and Answers What is the structure and function of the ribosome? Ribosomes consist of RNA and proteins and they help with synthesizing proteins. There is a large and small subunit. How does the structure of the ribosome aid in the function? The structure of the ribosome allows proteins to be made inside or outside the cell. What are the three types of RNA involved in the structure or function of the ribosome? messenger (mRNA) is...

AP Biology Unit 1.5 AP Exam review Questions and Answers How does a non polar R group substitution affect the folding of a protein? A non polar R group substitution can change the structure of a protein because it will cause the protein to fold differently. This different folding will cause the Non polar region to fold inward. Due to the fact that structure controls function, the substitution of a non polar R group will result in a change in function due to the structure change How does ...
