2. DNA is double stranded; each nucleotide is paired with its complementary base. Adenine is bound to thymine, and cytosine is bound to guanine. Link the complementary nucleotide magnets to your original strand to make
the complementary DNA strand.
Write the complementary sequence:

hope this helps you

have a nice day

Explanation:

In DNA, the complementary bases are adenine and guanine ; thymine and cytosine. Each nucleotide in DNA is composed of a nitrogen containing base, either guanine (G), adenine (A), thymine (T), or cytosine (C) as well as a monosaccharide sugar called deoxyribose and a phosphate group. The nucleotides are joined to one another in a chain by covalent bonds between the sugar of one nucleotide and the phosphate of the next, resulting in an alternating sugar-phosphate backbone. According to base pairing rules (A with T and C with G), hydrogen bonds bind the nitrogenous bases of the two separate polynucleotide strands to make double-stranded DNA.

organ system-an organ system is a group of organs that work together to perform one or more functions. each does a particular job in the body, and is made up of certain tissues.
