What is DNA?

  • Deoxyribonucleic acid, also known as DNA, is the molecule that carries the genetic material necessary for an organism's growth and operation.
  • The structure of DNA is a double helix, which is made up of two connected strands that loop around one another to resemble a twisted ladder.
  • Deoxyribose and phosphate groups alternately form the backbone of each strand.
  • One of the four bases—adenine (A), cytosine (C), guanine (G), or thymine (T)—is joined to each sugar.
  • Adenine forms chemical bonds with thymine while cytosine forms chemical bonds with guanine to join the two strands together.

All DNA is used to code for proteins

  • Protein-coding genes make up only around 1% of DNA; the remaining 99% is non-coding.
  • Protein synthesis instructions are not found in noncoding DNA.

All cells in a single organism contain the exact same DNA.

  • Yes, our body's cells all begin with identical copies of the same DNA.

DNA makes RNA which makes protein.

  • An explanation of the transmission of genetic information within a biological system is the core principle of the central dogma of molecular biology.
  • "DNA makes RNA, and RNA makes protein," 

DNA is single-stranded

  • Single-stranded (ssDNA) and double-stranded (dsDNA) DNA are two different types of DNA.
  • Two strands of DNA loop around one another to form double helices, which are dsDNA.
  • ssDNA can fold into various forms, although it typically takes the form of a stellate or star.
  • Only a few viruses use ssDNA to store genetic information, while the majority of organisms use dsDNA to encode genetic information.

RNA contains uracil

Adenine, cytosine, uracil, and guanine make up the four nitrogenous bases that makeup RNA. The pyrimidine uracil is structurally related to the pyrimidine thymine, which is present in DNA. Uracil can base-pair with adenine, just like thymine.

Therefore, options B, C, D, and E are correct.
