Telomeres and Telomerase: Structure and Functions
Telomeres are the structure of nucleoproteins that are present at the end of chromosomes in eukaryotes (Rhodes & Giraldo, 1995). These telomeres are similar to the cap that preserves the … Read more
Genetics is a branch of natural science that deals with heredity due to the transmission of genes, gene regulation, and gene manipulation.
Telomeres are the structure of nucleoproteins that are present at the end of chromosomes in eukaryotes (Rhodes & Giraldo, 1995). These telomeres are similar to the cap that preserves the … Read more
There are 23 pairs of chromosomes in each human cell and hundreds of thousands of distinct genes on each chromosome. An individual inherits two versions of each gene, known as … Read more
The genotypic ratio is the depiction of the ratio of the resulting patterns and frequencies of inherited genes after crossing in the offspring of organisms. In simple language, it is … Read more
Chromosomes are long thread-like structures of DNA that contain part or all of the genetic material of an organism. Chromosomal Mutation Definition The chromosomal mutation is the process of change … Read more
Natural selection definition Natural selection is a process of adaptation by an organism to the changing environment by bringing selective changes to its genotype or genetic composition. Artificial selection definition … Read more
Polygenic inheritance is defined as some phenotypic character determined by the additive effect of more than one gene on a single character. Two types of genes and alleles are involved … Read more
A Monohybrid cross is a type of genetic cross between two individuals with homozygous genotypes of a single character or trait, often resulting in an opposite phenotype. Steps of Monohybrid … Read more
Mendel’s Law of Independent Assortment states that ‘when the parents differ from each other in two or more pairs of contrasting characters, the inheritance of one pair of characters is … Read more
Okazaki fragments are short DNA nucleotide sequences with an RNA primer at the 5′ end that are synthesized discontinuously and later joined by the enzyme DNA ligase to form the … Read more
Chromosomes are essential components of the genetic material located in the nucleus of cells. They are thread-like structures that consist of DNA and proteins. Homologous chromosomes, also known as homologs, … Read more
