Which reason explains why nerve cells function differently than muscle cells?
In nerve cells all the genes are expressed.
In muscle cells all the genes are expressed.

DNA is considered a "universal" molecule, which allows scientists to insert genes from one animal into another, this is made possible because...
DNA, is not universal, it is in fact radically different between species.
all organisms have a nucleus which stores DNA
all organisms have the same sequence of nucleotides of DNA
all organisms have the same components or nucleotides of DNA
A mutation is defined as:
A change in the cell's structure
Anything that changes in an embryo
Any change in the physical features of a human
A change in the DNA sequence
Delray has dimples and his wife does not. Delray has a homozygous dominant genotype for dimples, and his wife has a homozygous recessive genotype for no dimples.
If Delray and his wife decide to have children, then which Punnett square correctly shows the probability of them having a child with dimples?
