Gene Mutations and DNA repair

Gene Mutation and DNA repair Mutation can happen during the recombination or replication. It is the permanent change that happens to the sequence of the DNA in the nucleotide. The cause of mutation within the DNA can be due to insertion of base pair, deletion or substitution. Mutations are not harmful until they cause a tumor or cell death. The fatal outcomes of the gene mutation are the reason that DAN repair is important. Before understanding DNA repair, it is important that we understand the Read more [...]

Regulation of Gene Expression

Regulation of gene expression Gene expression is the natural procedure in which the genetic codes also called the nucleotide sequence is directly used for the synthesis of the proteins. It helps in the production of cell structure. The genes that are used for coding the amino acids of the cell are known as the structural proteins. There are two main stages of the gene expression.Transcription In the process, the message RNA is produced with the help of the enzymes RNA polymerase and the result Read more [...]

Types of Gene Mapping

Gene mapping and it types Gene mapping is the process in which we determine the linear order due to which the genetic units are arranged according to genetic order. For instance, there are three different genes E, F, and G then the genetic map will have a different order of arrangement like: EFG EGF FGE FEG GEF GFEGene mapping also plays an important role in the determination of the distance between the genetic units.Types of gene mapping There Read more [...]

Pedigree Analysis and its Applications

Pedigree analysis and applications In people, controlled crosses can't be manufactured, so the genetic specialists must fall back on investigating family records with the expectation that enlightening mating has been influenced that to can be utilized to conclude strength related to X-linked and autosomal inheritance. The pieces of information in the family must be translated distinctively relying upon one of the phenotypes that differ is an uncommon issue or if the two phenotypes related to the Read more [...]

Basic Principles of Heredity

Basic principles of Heredity The basic principle of heredity comes from the first theory that was proposed in 1866 by Gregor Mendel. Mendel's research was based on the pea plant but the principles are applied to both plants and animals. It helps us to understand how we inherit different traits like eye and even the tongue rolling ability.Inheritance in pea plant There are 7 traits in the pea plant and Mendel selected all those that had two forms. Pea color (yellow or green) Pea Read more [...]

Introduction to Genetics

 Genetics :What is Genetics ?            Gеnеtісѕ іѕ thе ѕtudу оf how genes brіng about сhаrасtеrіѕtісѕ, оr trаіtѕ, іn lіvіng thіngѕ and hоw thоѕе сhаrасtеrіѕtісѕ are іnhеrіtеd. Gеnеѕ are роrtіоnѕ оf DNA mоlесulеѕ that determine сhаrасtеrіѕtісѕ of living things. Thrоugh thе рrосеѕѕеѕ of meiosis and rерrоduсtіоn, genes are trаnѕmіttеd frоm one gеnеrаtіоn tо thе next.          Thе Read more [...]

Recombinant DNA technology

What is recombinant DNA technology ?Rесоmbіnаnt DNA tесhnоlоgу is a tесhnоlоgу that allows DNA tо be produced vіа artificial means. Thе рrосеdurе hаѕ bееn uѕеd to change DNA in lіvіng оrgаnіѕmѕ аnd may have even mоrе рrасtісаl uses іn the future. It іѕ аn area оf mеdісаl ѕсіеnсе thаt іѕ just beginning tо bе rеѕеаrсhеd іn a concerted еffоrt. Recombinant DNA technology emerged as a response to the Read more [...]

DNA replication

What is DNA?          DNA stands for Deoxyriobo-Nucleic-Acid, a complex molecule that contains each and every information necessary to build and maintain organisms. All living beings have DNA within their cells. More interestingly, nearly every cell in a multi-cellular living organism possesses the full set of DNA required for that organism.DNA does a lot more than only specifying the structure and function of living things - it also serves as the primary unit of heredity in all Read more [...]

Transcription and Translation in Eukaryotes

What are eukaryotes? These are organisms whose cell structure such as organelles is enclosed within the membrane. The nucleus is the defining cell structure that sets eukaryotic cells apart from the prokaryotic cells. The presence of the nucleus gives these organisms their names. Being more complex than Prokaryotes, they make up all fungi, plant, animals such as amoeba. Eukaryotic cells are known for their strong cytoskeleton and their internal membranes. The cytoskeleton is made of proteins Read more [...]

Transcription and Translation in Prokaryotes

Introduction Prokaryotes are singled celled organisms and may be referred to as the earliest form of the most primitive life on earth. They include bacterial, prokaryotes and Achaeans. They are able to survive in a variety of environments including extreme habitats like swamps, hot springs, wet lands and the guts of animals. Prokaryotic cells are less complex when compared to eukaryotic cells. They lack a true nucleus and no DNA molecules. The following can be found in the bacterial cell: Capsule, Read more [...]
