Which of the following mutations is likely to have the greatest effect on the resulting polypeptide? a. deletion of a single nucleotide b. base substitution mutation c. silent mutation d. neutral mutation

B. base substitution mutation

Explanation:

Base substitution mutation is likely to have the greatest effect on the resulting polypeptide.

1. the energy lost to disorder metabolism     -entropy

2. related to or possessing motion potential     -kinetic

3. all of the chemical reactions in an organism required for maintenance of the processes of life entropy     -metabolism

4. possible; ability to go into action or perform work kinetic     -potential

5. the study of energy and its transformations thermodynamics     -thermodynamics

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
