The nucleotides are linked together for the formation of two long strands which spiral to produce a structure known as the double-helix which resembles that of a ladder wherein the sugar and phosphate molecules form the sides while the rungs are formed by the bases.
What are the different types of RNA?
What are the three types of RNA? 1 Messenger RNA ( mRNA) copies portions of genetic code, a process called transcription, and transports these copies to ribosomes, which are the cellular factories that facilitate the production of proteins from this code. 2 Transfer RNA ( tRNA) is responsible for bringing amino acids, basic protein building blocks, to these protein factories, in response to the coded instructions introduced by the mRNA. This protein-building process is called translation. 3 Finally, Ribosomal RNA ( rRNA) is a component of the ribosome factory itself without which protein production would not occur 3.
What are the bases of DNA?
Bases. The nitrogen bases in DNA are the basic units of genetic code, and their correct ordering and pairing is essential to biological function . The four bases that make up this code are adenine (A), thymine (T), guanine (G) and cytosine (C).
What is the sugar in DNA called?
Both DNA and RNA are built with a sugar backbone, but whereas the sugar in DNA is called deoxyribose (left in image), the sugar in RNA is called simply ribose (right in image).
What is the purpose of DNA?
DNA encodes all genetic information, and is the blueprint from which all biological life is created. And that’s only in the short-term. In the long-term, DNA is a storage device, a biological flash drive that allows the blueprint of life to be passed between generations 2. RNA functions as the reader that decodes this flash drive.
How many strands does DNA have?
DNA consists of two strands, arranged in a double helix. These strands are made up of subunits called nucleotides. Each nucleotide contains a phosphate, a 5-carbon sugar molecule and a nitrogenous base. RNA only has one strand, but like DNA, is made up of nucleotides. RNA strands are shorter than DNA strands.
Where are ribosomes located?
Ribosomes are formed in an area of the nucleus called the nucleolus, before being exported to the cytoplasm, where some ribosomes float freely. Other cytoplasmic ribosomes are bound to the endoplasmic reticulum, a membranous structure that helps process proteins and export them from the cell 6 .

What is DNA?
DNA is the abbreviation of Deoxyribonucleic Acid. In human, DNA carries the genetic information in the form of special nucleotide fragments called genes. Genes encode for proteins. Within the cells, DNA molecules tightly fold with histone proteins and arrange into long thread-like structures called chromosomes. Human genome constitutes 23 chromosome pairs. The total length of the chromosome is nearly 2 meters (nearly the height of the human). Since the entire length of DNA tightly coils with histone proteins, the entire 2m DNA chain can reside inside the nucleus.

Is DNA the same as RNA?
DNA and RNA vaccines work the same way as each other, but have some differences. With a DNA vaccine, the virus’ genetic information “is transmitted to another molecule that is called the messenger RNA (mRNA),” Gennaro says. This means with an RNA or mRNA vaccine, you’re one step ahead of a DNA vaccine.
Do DNA and RNA have the same immune response?
Based on research so far, Cifuentes-Kottkamp says that it looks like both DNA and RNA vaccines induce similar immune responses. “But since both are under clinical trials, we still have a lot to learn from them,” she adds.
Do DNA and RNA work the same?
DNA and RNA vaccines have the same goal as traditional vaccines, but they work slightly differently .
Is DNA a risk?
Gennaro says that with a DNA vaccine, there is always a risk it can cause a permanent change to the cell’s natural DNA sequence. “Usually, there are ways in which DNA vaccines are made that try to minimize this risk, but it’s a potential risk,” she says.
