Questions and Answers
Describe the role of RNA in cells and its relationship with DNA.
RNA is used to translate the information stored in DNA and help build proteins. Without RNA, the information in DNA would be useless.
Explain the role of DNA in a cell and its importance for an organism's survival, growth, and reproduction.
DNA carries all the information an organism needs to survive, grow, and reproduce. It is responsible for storing genetic information.
List the four different bases found in DNA and the three bases found in RNA.
DNA bases: adenine (A), thymine (T), guanine (G), and cytosine (C). RNA bases: adenine (A), uracil (U), guanine (G), and cytosine (C).
What are the two main differences between DNA and RNA in terms of their structure?

Study Notes
Role of RNA in Cells
- RNA (Ribonucleic acid) plays a crucial role in protein synthesis, carrying genetic information from DNA to the ribosomes for translation into proteins.
- RNA acts as a messenger, carrying genetic information from DNA to the ribosomes, and as a catalyst, facilitating protein synthesis.
Role of DNA in Cells
- DNA (Deoxyribonucleic acid) contains the genetic instructions necessary for an organism's survival, growth, and reproduction.
- DNA is the primary source of genetic information, passed from one generation to the next.
Bases in DNA and RNA
- DNA contains four different bases: adenine (A), guanine (G), cytosine (C), and thymine (T).
- RNA, on the other hand, contains adenine (A), guanine (G), cytosine (C), and uracil (U) instead of thymine.
Structural Differences between DNA and RNA
- DNA is a double-stranded molecule, forming a double helix structure, whereas RNA is usually single-stranded.
- DNA contains the sugar deoxyribose, whereas RNA contains the sugar ribose.
