The answer is histone
acetylation decreases with age, so sodium butyrate may improve memory in older
mice
<span>This
is because Histone deacetylase (HDAC) inhibitors increase histone acetylation
and enhance both memory and synaptic plasticity of brain neurons. It also regulates
cell proliferation and neuroblast differentiation in the dentate gyrus hence
improve memory function especially the hippocampus-dependent memory. </span>

1- Mendel came to the conclusion that the inheritance of every trait is determined by units (now called genes) that are passed on to the offspring and remain unchanged.
2-That when two alleles of a pair are heterozygous, the dominant allele will be expressed while the recessive one will not.
Hope this helps!
