[1] [2] The standard genetic code is traditionally represented as an RNA codon table, because when proteins are made in a cell by ribosomes, it is messenger RNA (mRNA) that directs protein synthesis. [2] [3] The mRNA sequence is determined by the sequence of genomic DNA. [4] In this context, the standard genetic code is referred to as ...
On 1 July 2021, Cadila Healthcare applied to the Drugs Controller General of India (DCGI), seeking approval for Restricted Use in Emergency Situation for the vaccine. [23] On 20 August 2021, the Subject Expert Committee of the Central Drugs Standard Control Organisation (CDSCO) recommended that the DCGI grant the approval, [ 24 ] which the DCGI ...
The DNA is stored in a population of identical vectors, each containing a different insert of DNA. In order to construct a genomic library, the organism's DNA is extracted from cells and then digested with a restriction enzyme to cut the DNA into fragments of a specific size.
A distinct group of DNA-binding proteins are the DNA-binding proteins that specifically bind single-stranded DNA. In humans, replication protein A is the best-understood member of this family and is used in processes where the double helix is separated, including DNA replication, recombination and DNA repair.

DNA vaccine and Gene therapy techniques are similar. DNA vaccines have been introduced into animal tissues by multiple methods. In 1999, the two most popular approaches were injection of DNA in saline: by using a standard hypodermic needle, or by using a gene gun delivery. [31] Several other techniques have been documented in the intervening years.
Junk DNA (non-functional DNA) is a DNA sequence that has no known biological function. [ 1 ] [ 2 ] Most organisms have some junk DNA in their genomes —mostly pseudogenes and fragments of transposons and viruses—but it is possible that some organisms have substantial amounts of junk DNA.
The regular structure and data redundancy provided by the DNA double helix make DNA well suited to the storage of genetic information, while base-pairing between DNA and incoming nucleotides provides the mechanism through which DNA polymerase replicates DNA and RNA polymerase transcribes DNA into RNA. Many DNA-binding proteins can recognize ...
An example is they separate when heated at a higher temperature than dissimilar sequences, a process known as "DNA melting". [2] [3] [4] To assess the melting profile of the hybridized DNA, the double-stranded DNA is bound to a column or filter and the mixture is heated in small steps.
