The frequency at which mutants exist within a population. Mutations’ effect in the genetic information of an organism may occur naturally or be artificially brought about by a mutagen. This change in genetic information can lead to a variety of consequences, depending on which genetic information mutated, how important it is, and in what stage of the life cycle it occurred in.
Mutations can also influence the phenotype of an organism. This tutorial looks at the effects of chromosomal mutations, such as nondisjunction, deletion, and duplication. ..
Humans are diploid creatures. This means that for every chromosome in the body, there is another one to match it. However, there are organisms that have more than two sets of chromosomes. The condition is called polyploidy. Know more about this topic through this tutorial...
This tutorial looks at the mutation at the gene level and the harm it may bring. Learn about single nucleotide polymorphisms, temperature-sensitive mutations, indels, trinucleotide repeat expansions, and gene duplication...
Human consciousness and behavior are an interesting topic since they are determined and controlled by the brain. Consciousness can be defined by behavior or by electrical pattern of brain activity. Read this tutorial to learn about brain activities, such as sleep, attention, emotion, motivation, consciousness disorders, learning, and memory...
This tutorial is a continuation of the first lesson on chromosomal mutation. Here, find out the chromosomal aberrations involving the genes. ..
Genes are expressed through the process of protein synthesis. This elaborate tutorial provides an in-depth review of the different steps of the biological production of protein starting from the gene up to the process of secretion. Also included are topics on DNA replication during interphase of the cell cycle, DNA mutation and repair mechanisms, gene pool, modification, and diseases...
