The key difference between cloning vector and expression vector is that cloning vector carries a foreign DNA fragment into the host cell while expression vector facilitates the expression of genes into proteins. Vector is an important term in molecular biology. In recombinant DNA technology, the main role of a vector is to provide a mode […]
Difference Between Lagging and Leading Strand
The key difference between lagging and leading strand is that the synthesis of lagging strand is discontinuous and it occurs in the direction opposite to the growing replication fork while the synthesis of leading strand is continuous and it occurs in the same direction as the growing replication fork. DNA replication is an important biological […]
Difference Between mRNA and tRNA
The key difference between mRNA and tRNA is that the mRNA carries the genetic information of a gene to produce a protein while the tRNA recognizes the three nucleotide mRNA sequences or codons and carries amino acids to ribosomes according to the codons of the mRNA. Nucleic acids such as DNA and RNA are macromolecules […]
Difference Between Heterochromatin and Euchromatin
The key difference between heterochromatin and euchromatin is that heterochromatin is the highly packed form of chromatin which is generally inactive while euchromatin is the loosely packed form of chromatin which is generally active. Chromatin is the structure that holds the DNA strand of a chromosome. Heterochromatin and euchromatin are the two main types of […]
Difference Between Autosomes and Sex Chromosomes
The key difference between autosomes and sex chromosomes is that the autosomes contain genes that are responsible for the determination of somatic characteristics while the sex chromosomes contain genes that determine sex and sex-related characteristics of an organism. The most important structures in a cell during the cell division are the chromosomes, which contain DNA. […]
Difference Between Plasmid and Vector
The key difference between plasmid and vector is that plasmid is a type of vector and is a circular, double-stranded extra-chromosomal DNA molecule of some bacterial species while vector is a self-replicating DNA molecule that acts as a vehicle for delivering foreign DNA into host cells. Genetic engineering is a novel field of Biotechnology which […]
Difference Between Genomic and Plasmid DNA
The key difference between genomic and plasmid DNA is that genomic DNA is essential for the survival of organisms including bacteria while plasmid DNA is not essential for the survival of bacteria. Every living organism has genetic material that controls its overall functioning. Genetic material mainly exists as chromosomal DNA. In eukaryotes, genomic DNA is […]
Difference Between Prokaryotic and Eukaryotic Transcription
The key difference between prokaryotic and eukaryotic transcription is that the prokaryotic transcription takes place in the cytoplasm while the eukaryotic transcription takes place inside the nucleus. In a cell, DNA carries information from generation to generation controlling the activities of a cell. Moreover, DNA is responsible for synthesizing all proteins that have a functional […]
Difference Between Prokaryotic and Eukaryotic DNA
The key difference between prokaryotic and eukaryotic DNA is that the prokaryotic DNA freely floats in the cytoplasm while the eukaryotic DNA situates inside the nucleus. There are two major categories of living organisms such as prokaryotes and eukaryotes. They differ from each other by their cellular organization. Accordingly, prokaryotes have a simple cellular organization. […]
Difference Between DNA and Chromosome
The key difference between DNA and chromosome is the organization of their structure. DNA is a double-stranded coiled polymer composed of deoxyribonucleotides while the chromosome is a thread like structure composed of DNA molecules tightly coiled with histone proteins. DNA and chromosomes are two different levels of structural organizations of the genetic material. DNA is […]
