In 1970, hamilton smith isolated the first restriction enzyme. restriction enzymes are used to cut strands of dna at specific points. this discovery led to the development of recombinant dna, which is widely used in several scientific industries to produce proteins and hormones more cheaply and in much larger quantities than earlier methods. the change in scientific knowledge caused by smith’s discovery most directly affected which sector of society?

dude i stopped reading after the first 7 words but hey you seem real smart thats awesome have a great day

this is true, assuming that the allele is completely recessive and incomplete dominance is not a factor.

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
