Key Difference – T4 vs T7 DNA Ligase DNA ligase is an important enzyme used in molecular biology techniques. It functions as a molecular glue to join nucleotides by forming phosphodiester bonds between nucleotides. The phosphodiester bonds are formed between the 3’ hydroxyl end of the sugar moiety and the 5’ end phosphate group. […]
Difference Between Inducible and Repressible Operon
Key Difference – Inducible vs Repressible Operon An operon is a functioning unit of genomic DNA containing a cluster of genes under the control of a single promoter. Gene regulation is achieved by the control of an operon through induction or repression. Operons are of two types: inducible operons and repressible operons. Inducible operon […]
Difference Between Missense and Nonsense Mutation
Key Difference – Missense vs Nonsense Mutation DNA is constantly subjected to changes due to various factors including internal and environmental origin. DNA damages and mutations are two such changes that occur in DNA. Mutation is defined as a base change in the DNA sequence. Mutations cannot be recognized and repaired by enzymes. Mutated […]
Difference Between VNTR and STR
Key Difference – VNTR vs STR DNA studies have immense utility in understanding and determining phylogenetic relationships, diagnosing genetic diseases and mapping organism’s genomes. Several techniques associated with DNA analysis are used for the identification of a particular gene or a DNA sequence in a pool of unknown DNA. They are known as genetic […]
Difference Between Troponin and Tropomyosin
Key Difference – Troponin vs Tropomyosin It is important to understand the mechanism of muscle contraction and relaxation properly before learning the difference between troponin and tropomyosin. Muscle fibers are composed of myofibrils. Myofibrils are made up of long proteins arranged in sections called sarcomeres, which are the basic building blocks of striated muscle […]
Difference Between Minisatellite and Microsatellite
Key Difference – Minisatellite vs Microsatellite Repetitive DNA is the nucleotide sequences repeating over and over again in the genome of organisms. Repetitive DNA accounts for a significant fraction of genomic DNA, and there are three main types named tandem repeats, terminal repeats and interspersed repeats. Tandem repeats are the highly repeated sequences which […]
Difference Between Coding and Noncoding DNA
Key Difference – Coding vs Noncoding DNA A genome of an organism is defined as the complete set of DNA including all of its genes. The genome is represented by the whole set of chromosomes present in the nucleus of a cell. DNA comprises specific nucleotide sequences which have different structural and functional properties. Some of […]
Difference Between Recombinant and Nonrecombinant
Key Difference – Recombinant vs Nonrecombinant DNA is the genetic material of almost all organisms. It is composed of nucleotides arranged in long chains. There are natural mechanisms and enzymes which are able to change the nucleotide sequences and structures of DNA. Hence, DNA are frequently subjected to changes. Genetic recombination, which occurs during […]
Difference Between Linked and Unlinked Genes
Key Difference – Linked vs Unlinked Genes Genes are the specific DNA sequences in chromosomes. There are 46 chromosomes in the human genome. Among them, 22 homologous pairs are called autosomes and one pair is known as sex chromosome. Thousands of genes are located on each chromosome. Some genes are closely situated in the […]
Difference Between Original and Mutated Sequences
Key Difference – Original vs Mutated Sequences In a DNA sequence, there are four naturally occurring nucleotides. Each DNA sequence has a unique order of nucleotides. In a gene region, a precise nucleotide sequence is extremely important due to the genetic information it possesses to synthesize a specific protein. A single nucleotide difference can […]
