Which enzyme is used in 5 end Labelling?
5′ end labeling of DNA (or RNA) is usually carried out using T4 PNK. SP6 is a DNA-dependent RNA polymerase. It uses a DNA template that has a specific SP6 phage promotor.
What labels are given to the ends of a nucleic acid?
Nucleic acids can be labeled at their 5´ end, 3´ end, or throughout the molecule depending on the particular application, including: to generate information on gene integrity and copy number (blot) to diagnose specific sequences and chromosomal aberrations (in situ hybridization)
Why are the ends of DNA and RNA labeled 5 and 3 end?
In a single strand of DNA or RNA, the chemical convention of naming carbon atoms in the nucleotide pentose-sugar-ring means that there will be a 5′-end (usually pronounced “five-prime end”), which frequently contains a phosphate group attached to the 5′ carbon of the ribose ring, and a 3′-end (usually pronounced “three …
Is RNA translated 5 to 3?
Genetic code During transcription, the RNA polymerase read the template DNA strand in the 3′→5′ direction, but the mRNA is formed in the 5′ to 3′ direction. The codons of the mRNA reading frame are translated in the 5′→3′ direction into amino acids by a ribosome to produce a polypeptide chain.
How is the 5 prime end of DNA different from the 3 prime end?
A nucleic acid strand is inherently directional, and the “5 prime end” has a free hydroxyl (or phosphate) on a 5′ carbon and the “3 prime end” has a free hydroxyl (or phosphate) on a 3′ carbon (carbon atoms in the sugar ring are numbered from 1′ to 5′; ).
How will you do following I Labeling of DNA at 5 end?

How would you label the 5 end of an oligonucleotide?
Oligos can be labeled at either the 3′ or the 5′ end. Using polynucleotide kinase and ATP (γ-32P), the 5′ end is labeled. Using terminal transferase and deoxynucleotide triphosphate the 3′ end is labeled. 32P or 35S nucleotides can be used for labeling.
What does 5 prime and 3 prime mean?
Each end of DNA molecule has a number. One end is referred to as 5′ (five prime) and the other end is referred to as 3′ (three prime). The 5′ and 3′ designations refer to the number of carbon atom in a deoxyribose sugar molecule to which a phosphate group bonds.
