Sagot :

Answer:

1.The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA)

2.Double Helix

3.The sides of the ladder are made of alternating sugar and phosphate molecules.

4.In DNA, the "rungs" between the two strands of DNA are formed from the nitrogenous bases adenine, thymine, guanine and cytosine

5.nucleotides

6.a phosphate group, a 5-carbon sugar, and a nitrogenous base.

7.deoxyribose

8.Adenine, thymine, cytosine and guanine

9.uracil

10.The two strands are held together by hydrogen bonds between the bases, with adenine forming a base pair with thymine, and cytosine forming a base pair with guanine.
