oncogene
so after it changes it is called a gene
b: the organism, but not its offspring
Noonan syndrome is primarily caused by mutations in the PTPN11 gene, located on chromosome 12. This gene provides instructions for making a protein involved in cell signaling and development. Changes in this gene can disrupt normal cell signaling pathways and lead to the characteristic features of Noonan syndrome.
Gene perturbation refers to changes in the activity or expression of genes, which can have significant effects on cellular function and development. These changes can disrupt normal cellular processes, leading to altered protein production, signaling pathways, and ultimately impacting the development and function of the cell. Gene perturbation can result in a variety of outcomes, including cell death, abnormal growth, or changes in cell behavior, all of which can have profound effects on overall cellular function and development.
Sickle Cell Anaemia is a single gene defect (Hb gene).
The protein that the gene codes for changes or may even cease to be produced, depending on the change to the gene.
Smallest to largest: Gene (a place on a chromosome); chromosome (there are 46 in human cells); and DNA (because it accounts for all the genetic material in a cell).

A mutation is a permanent change in the gene or chromosome of a cell that can result in altered characteristics or function. Mutations can arise spontaneously during cell division or in response to external factors such as radiation or chemicals. These changes can be inherited or occur randomly in somatic cells.
When it's a recessive gene.
Gene mutation involves changes in the DNA sequence, which can lead to altered protein production. Chromosomal changes involve modifications in the structure or number of chromosomes, impacting gene expression and cell function. Epigenetic changes can affect gene activity without altering the DNA sequence, influencing how genes are expressed through modifications like methylation or histone acetylation.
