you find a way to attach either a red or green fluorescent dye to nucleotides. double-stranded dna molecules with both strands labeled red fluoresce red, those with both strands labeled green fluoresce green, and those with one strand labeled red and the other green fluoresce yellow. you grow human cells in the presence of "red" nucleotides until both dna strands of all chromosomes fluoresce red. you then allow one round of dna replication in the presence of "green" nucleotides. what pattern of fluorescence do you expect to see in the sister chromatids of each chromosome?

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.
