The key difference between start codon and stop codon is that start codon is the trinucleotide sequence which marks the beginning of the sequence that translates into a protein while stop codon is the trinucleotide sequence which marks the end of the sequence that translates into a protein. Genetic code of a gene contains the […]

The key difference between TATA and CAAT box is that TATA box is a conserved nucleotide region which has a consensus sequence of TATAWAW while CAAT box is a conserved nucleotide region with a consensus sequence of GGCCAATCT. TATA box and CAAT box are two regions of nucleotides that influence transcription of eukaryotic genes. They […]

The key difference between primer and promoter is that primer is a commercially synthesized short DNA sequence which is used in PCR for amplification of a target DNA sequence while promoter is a specific DNA sequence which provides a secure initial binding site for RNA polymerase and transcription factors in order to initiate transcription. Primer […]

The key difference between CRISPR and CRISPR Cas9 is that CRISPR (clustered regularly interspaced short palindromic repeat) is a naturally occurring prokaryotic immune defence mechanism while CRISPR cas9 is an RNA-guided Cas9 nuclease which is a part of the CRISPR adaptive immune system. CRISPR is an antiviral defence immune system found in bacteria and archaea. […]

The key difference between CDS and cDNA is that CDS or coding sequence is the part of a transcript that is actually translated into protein while cDNA sequence is a DNA sequence derived from the mRNA by reverse transcription. A gene is a nucleotide sequence which codes for a protein. It consists of different regions […]

The key difference between mutagen and teratogen is that mutagen is a substance or an agent that causes a change in the sequence of the DNA of an individual while a teratogen is an agent that causes harm to the fetus or the developing embryo during pregnancy. Mutagens and teratogens are usually chemical agents. However, […]

The key difference between DNA and RNA nucleotide is that DNA nucleotide or deoxyribonucleotide contains deoxyribose sugar while RNA nucleotide or ribonucleotide contains ribose sugar. Nucleotides are the basic unit of nucleic acids. They are the building blocks or monomers of DNA and RNA. They link with each other to form a polynucleotide chain, which […]

The key difference between consensus PCR and pan PCR is that consensus PCR always targets conserved regions whereas Pan PCR targets variable regions to identify different strains of a group Polymerase chain reaction (PCR) is a gene amplification technique that consists of three main steps as denaturation, annealing and extension. This is widely used in […]

The key difference between conserved and consensus sequence is that conserved sequence refers to similar sequences of nucleic acids or amino acids that occur in different or same species over generations while consensus sequence is a commonly encountered nucleotides sequence or amino acid sequence found in a highly conserved region of DNA or RNA or […]

The key difference between radioactive and nonradioactive probes is that radioactive probes are single-stranded DNA or RNA sequences that are labeled with radioactive isotopes while nonradioactive probes are single-stranded DNA or RNA sequences that are labeled with a chemical tag or a fluorescent tag. Nucleic acid hybridization is an important technique in molecular biology, especially […]
