, RNA polymerase assembles a strand of mRNA complementary to the
noncoding strand of DNA.
RNA polymerase moves over the gene and unzips the double helix to form
a "transcription bubble."
RNA polymerase binds to a gene's promoter.
In order to visualize the DNA for karyotype, ___.

DNA is stained to visualize the DNA
What is DNA polymerase?

An enzyme that carries out DNA replication
In incomplete dominance , one allele is NOT fully dominant over another, so the

phenotypes .
