In a DNA double helix, where would you find hydrogen bonds? Between the bases connecting the anti-paralel DNA molecules. Between the 2'OH and the 3'OH group of an individual nucleotide. Between the base and the sugar of an individual nucleotide. Between each sugar and phosphate of the backbone.
I need help with a biology question, Which of the following does not apply to the known model of DNA? Group of answer choices The backbone of the helix consists of sugar-phosphates units of the nucleotides. The two strands of the DNA helix are antiparallel. The two strands of the helix are held together by covalent bonds. The purines are attracted to pyrimidines
3. On the diagram below... Using green dashed lines, draw in the hydrogen bonds on the right figure. Using the same color, circle the location of the H-bonds on the left figure. - Using a red pen, circle where the molecules have a negative charge on the right figure. Using the same color, color the area with the negative charge in the left figure. - Is this DNA or RNA? Explain two ways that you know.

23. What are the four nucleotides of DNA? Group of answer choices cytosine, guanine, thymine, adenine cytosine, guanine, lysine, adenine cytosine, guanine, uracil, adenine cytosine, guanie, trypsin, adenine
6. In RNA, why can uracil be used in place of thymine? * The structural difference between thymine and uracil does not affect hydrogen bonding to adenine Thymine and uracil are actually identical bases, but they're named differently because one is in DNA and the other is in RNA Uracil forms two hydrogen bonds with adenine, but using different atoms than thymine O Uracil can interact with adenine via three hydrogen bonds 7. At least how many different types of RNA are there in eukaryotic cells? * 1: just messenger RNA 2: messenger RNA and ribosomal RNA 3: messenger RNA, ribosomal RNA, and transfer RNA 6: the three listed above in C, plus microRNA, small interfering RNA, and small nuclear RNA 1
