DNA vs RNA
Difference, Examples & Quiz
What's the difference? Which one is correct?
Definition: DNA stands for deoxyribonucleic acid. It is a molecule that carries the genetic instructions used in the growth, development, functioning, and reproduction of all known living organisms.
Usage: DNA is used to store and transmit genetic information. It is essential for various biological processes, such as protein synthesis and inheritance.
- 1. The DNA in our cells determines our unique traits and characteristics.
- 2. Forensic scientists use DNA analysis to identify individuals and solve crimes.
- 3. DNA sequencing has revolutionized the field of genetics and has led to significant advancements in medicine and biotechnology.
Definition: RNA stands for ribonucleic acid. It is a molecule that plays a crucial role in protein synthesis and gene expression.
Usage: RNA is involved in the transfer of genetic information from DNA to the ribosomes, where proteins are synthesized. It also has other important functions, such as regulating gene expression and catalyzing biochemical reactions.
- 1. Messenger RNA (mRNA) carries the genetic information from DNA to the ribosomes for protein synthesis.
- 2. Transfer RNA (tRNA) helps in translating the genetic code into amino acids during protein synthesis.
- 3. Ribosomal RNA (rRNA) forms an integral part of the ribosomes, where proteins are synthesized.
DNA stands for Deoxyribonucleic Acid, which is a molecule that carries the genetic instructions used in the growth, development, functioning, and reproduction of all known living organisms. RNA stands for Ribonucleic Acid, which is a molecule that plays a crucial role in the synthesis of proteins within cells.

FAQs
What is DNA?
DNA stands for deoxyribonucleic acid. It is a molecule that carries the genetic instructions used in the growth, development, functioning, and reproduction of all known living organisms.
What is RNA?
RNA stands for ribonucleic acid. It is a molecule that plays a crucial role in various biological processes, including protein synthesis, regulation of gene expression, and transmission of genetic information.
How is DNA structured?
DNA is a double-stranded helix structure composed of nucleotides. Each nucleotide consists of a sugar molecule (deoxyribose), a phosphate group, and one of four nitrogenous bases: adenine (A), thymine (T), cytosine (C), or guanine (G).
What are the functions of DNA?
DNA carries the genetic information that determines the traits and characteristics of an organism. It serves as a blueprint for the synthesis of proteins and plays a vital role in inheritance and evolution.
How does RNA differ from DNA?
RNA differs from DNA in several ways. RNA is usually single-stranded, contains the sugar ribose instead of deoxyribose, and the base uracil (U) replaces thymine (T). RNA is involved in protein synthesis and various cellular processes.
