protien can be effected bc there are certain acids in your body and if u add more mutation then it messes with all the acid and stuff in your body and can be very harmful
Answer: A. False, it should read “If a point mutation occurs in a tumor suppressor gene it can become inactivated. This allows the rate of cell division to increase unregulated.”
Explanation: I already know this for a fact.
Answer:
True
Explanation:
In inhibitory postsynaptic potentials, the opening of chlorine and potassium channels generally occurs so that chlorine enters, with a negative charge, and potassium leaves, with a positive charge. The synergistic effect of this ionic flow is the hyperpolarization of the cell, making it difficult for an action potential to occur.
Answer Choices:
DNA provides the energy needed for an organism to grow and function
DNA is copied into mRNA, which controls cellular functions
DNA codes for proteins, which allow an organism to grow and function
DNA unzips and each strand codes for a different amino acid
Answer:
DNA codes for proteins, which allow an organism to grow and function
Explanation:
DNA provides the energy needed for an organism to grow and function - this is false. DNA does not provide energy. A molecule called ATP, mostly produced by cellular respiration, provides energy for the cells to grow and function.
DNA is copied into mRNA, which controls cellular functions - this is false. While it is true that DNA is copied into mRNA, mRNA does not directly control cellular functions. Instead, mRNA is translated into proteins.
DNA codes for proteins, which allow an organism to grow and function - <u>this is true, as indicated above, DNA is transcribed to mRNA which is translated into proteins. Proteins carry out essentially all the functions in the cell</u>
DNA unzips and each strand codes for a different amino acid - this is false, DNA is transcribed into mRNA. Each mRNA codon (three bases) codes for a different amino acid
