Which base is found in DNA but not in RNA?
Have you ever wondered why an elephant invariably gives birth to an elephant baby and never to a different animal? Or why does a mango seed only grow into a mango plant and not some other? It occurs as a result of Inheritance (the process through which traits are passed down from one generation to the next). But who relays this information from the parent to the offspring? For transmitting any message, we need a messenger. In this case, the genetic materials, DNA, and RNA act as messengers to carry the information from one generation to another. Let's learn more about these genetic materials in more detail.
Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are the two primary forms of nucleic acids. DNA is the genetic substance present in all living species, from single-celled bacteria to multicellular animals. RNA, the other form of nucleic acid, is used mostly in protein production. In eukaryotes, DNA molecules never exit the nucleus and instead interact with the remainder of the cell through an intermediate. The messenger RNA serves as an intermediate in this process (mRNA).
Nucleotides are monomers that makeup DNA and RNA. The nucleotides unite to produce a polynucleotide, such as DNA or RNA. Each nucleotide consists of three parts:
In a nucleotide, every nitrogenous base is linked to a sugar molecule, which itself is linked to one or even more phosphate groups.
1. Which nitrogenous base is not present in RNA?
The thymine nitrogenous base is not present in RNA.
2. Name the bases present in RNA.
Adenine (A), Cytosine (C), Guanine (G), and Uracil (U) are the bases present in RNA.
3. Which bases are present in DNA?
The nitrogenous bases present in DNA are thymine (T), guanine (G), cytosine (C), and adenine (A). Thymine is the nitrogenous base which not found in RNA.
