2.6.1 3 Compare the structure of RNA and DNA

Both RNA and DNA are nucleic acids. RNA is a polymer of a nucleotide

in the form of a single strand. The nitrogen bases occur is Adenine,

Guanine, Thymine, and Uracil. The pentose sugar is a ribose. The bonds

that connect all the molecules together are covalent bonds. The phosphate

of one nucleotide is connected to the sugar of the adjacent nucleotide. The

sequence of nitrogen bases characterizes an RNA.

Draw a strand of RNA:

RNA functions in protein synthesis. RNA is present both in the nucleus

and the cytoplasm. There are three types of RNA: Messenger RNA

(mRNA), transfer RNA (tRNA, and ribosomal RNA (rRNA. These types

will assist in protein synthesis through translation and transcription. DNA

is a polymer of nucleotides. Just like RNA, each nucleotide is made of a

phosphate group, nitrogen base, and a pentose sugar. The pentose sugar
