Biology

Biology is the branch of science that primarily deals with the structure, function, growth, evolution, and distribution of organisms. It’s a methodological study of life and living things.

Biology is the scientific study of life. It spans multiple levels, from biomolecules and cells to organisms and populations12. All living things share common biological phenomena, such as reproduction, cell division, and the transmission of genetic material.

Mechanism of induced mutation: base analogs, base alteration, intercalation, pyrimidine dimer formation

Mechanism of induced mutation: base analogs, base alteration, intercalation, pyrimidine dimer formation

Mutations are alterations in the DNA sequence that can cause variances in genetic information. While some mutations occur naturally, others are produced by exposure to environmental or chemical sources. Understanding the mechanisms of induced mutation is critical in genetics, medicine, and environmental science. This essay will review the mechanisms of induced mutation, with a particular […]

Huntington's disease - Causes, Symptoms, Diagnosis and Treatment

Huntington’s disease-Causes, Symptoms, Diagnosis and Treatment

Huntington’s disease (HD) is a degenerative hereditary ailment that affects the brain, causing a gradual decline in physical and mental ability. It is a neurodegenerative condition that mostly affects the basal ganglia, which regulate movement and cognitive abilities. HD is defined by a combination of motor impairment, cognitive decline, and mental disorders. This essay will

Alpha-Thalassemia: Causes, symptoms, types, diagnosis and treatment

Alpha-Thalassemia: Causes, symptoms, types, diagnosis and treatment

Alpha-thalassemia is a genetic blood condition that impairs the production of hemoglobin, the protein in red blood cells that transports oxygen throughout the body. This disorder is caused by mutations or deletions in the HBA1 and HBA2 genes, which are required to produce alpha-globin chains, a critical component of hemoglobin. Understanding it involves thoroughly examining

Beta-thalassemia: Causes, types, symptoms, diagnosis, and treatment

Beta-thalassemia Beta-thalassemia is a genetic blood disorder that affects the production of hemoglobin, the protein in red blood cells responsible for carrying oxygen throughout the body. This disorder arises from mutations in the beta-globin gene, one of the two genes that make up hemoglobin. Causes and Inheritance It is inherited, meaning it is passed down
