What is an anticodon? Function, RNA Base Pairing

What is an anticodon? Anticodons are sequences of nucleotides that complement the codon. They are found in tRNA and allow tRNAs to produce the correct amino acids corresponding to mRNA during protein production. During protein production, amino acids are bound together in a string, such as beads on a necklace. The right amino acid must … Read more

What is a Phenotype? Examples of Phenotypes and Mendel’s Peas

What is a Phenotype? A Phenotype is the physical expression of DNA. Rather, a genotype is the chemical composition of DNA that causes a particular phenotype. DNA is first transferred to RNA, which is a separate information molecule, which can then be translated into protein. Phenotypes are caused by interactions of many different proteins produced by DNA. … Read more

Gene Definition, Overview, Examples, And Genetic Terms

Gene Definition A gene is a highly specific sequence of nucleotide monomers that can fully or partially regulate the expression of one or more traits in every type of living organism. Genes are formed from deoxyribonucleic acid (DNA) and in the case of some viruses, ribonucleic acid (RNA) polymers. Overview|Gene Definition It was Wilhelm Johansen … Read more

Abiogenesis Definition, Overview, Theory of Abiogenesis

Abiogenesis Definition Abiogenesis is the formation of organic molecules by forces other than organisms. While organisms can form carbon-carbon bonds relatively easily to enzymes, doing so would otherwise require large inputs of energy. Early in the history of science, this fact was used to dispute evolutionism, as it could not be imagined how organic molecules … Read more

Genetic Definition, History, And Impact

Genetic Definition Genetics is the study of genes and inheritance in living organisms. This branch of science has a fascinating history, stretching from the 19th century when scientists began to study how organisms inherited the traits of their parents, until today when we can read the “source code” of the living beings letter by letter. … Read more

Allele definition, Mendelian and Example

Allele definition An allele is the specific variation of a gene. Bacteria, because they have only one DNA ring, have one allele per gene per organism. In sexually reproducing organisms, each parent gives one allele for each gene, giving offspring two alleles per gene. Because alleles are only specific gene variants, different alleles are found … Read more

Transposable elements, Types, examples, applications

Transposable elements definition Transposable elements (TE, transposon, or jumping gene) Transposable elements (TE) or transposons can be defined as small mobile DNA sequences that move around chromosomes regardless of homology, and insertion of these elements can lead to deletions, inversions, chromosomal fusions, and even further rearrangements. complicated. Transposons are mobile genetic elements that often carry … Read more

Genetic Drift, Example, Types and explained

Genetic Drift Genetic drift is a change in the frequency of alleles in a population, due to a random selection of certain genes. Often, mutations in DNA cannot have any effect on the physical form of an organism. These genetic changes can increase or decrease in a population, just by chance. Genetic drift explained Although … Read more

Gene expression, Introduction and mechanism

Gene expression, Introduction and mechanism Introduction to Gene Expression Chemically, a gene is a segment of DNA or a specific sequence of nucleotides. Alkali sequences vary in different genes. The functional gene is a segment of DNA that controls the synthesis of proteins. Thus, we can say that the gene expresses itself as a protein … Read more
