A Group of Scientists Is Studying Memory in Mice

question 1

Multiple Choice

A group of scientists is studying memory in mice. They feed sodium butyrate, a histone deacetylase inhibitor, to a group of older mice and then subject them to memory exercises. How do you predict the memory of treated mice might compare with the memory of untreated mice?

• A) Histone acetylation increases with age, so sodium butyrate may improve memory in older mice.
• B) Histone acetylation increases with age, so sodium butyrate may impair memory in older mice.
• C) Histone acetylation decreases with age, so sodium butyrate may improve memory in older mice.
• D) Histone acetylation decreases with age, so sodium butyrate may impair memory in older mice.
• E) Histone acetylation is not associated with memory in mice.
