DNA and RNA

Question 1

Explain the role of DNA as a nucleic acid

Answer 1

DNA is an information molecule containing instructions for the synthesis of proteins

Question 2

Explain the role of RNA as a nucleic acid

Answer 2

RNA, more specifically mRNA carries genetic information that is translated by ribosomes into various proteins.
RNA is found in three forms - mRNA, tRNA rRNA

Question 3

Label the key components of DNA

Answer 3

nucleotide&raquo_space; sugar, phosphate, nitrogenous base
base pairing through weak hydrogen bond
formation of nucleic acid through phosphosidester bond and double helix arrangement

Question 4

Outline the differences between DNA and RNA nucleotides

Answer 4

DNA has thymine, RNA has uracil
DNA has deoxyribose sugar, RNA has ribose sugar
DNA has less oxygen, RNA has more oxygen

Question 5

identify the differences between DNA and RNA in terms of structure

Answer 5

DNA is double stranded, RNA is single stranded
DNA is larger than RNA
DNA is stable, RNA is unstable

Question 6

define the term UNIVERSAL when discussing the DNA and RNA code

Answer 6

Universal refers to the genetic code being the same for all living organisms
