What genes are made of?
DNA
Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. However, many genes do not code for proteins. In humans, genes vary in size from a few hundred DNA bases to more than 2 million bases.
Where are genes found in a cell quizlet?
Genes are contained in chromosomes, which are in the cell nucleus. A chromosome contains hundreds to thousands of genes.
What are genes What do genes contain instructions to create?
A gene is a short section of DNA. Your genes contain instructions that tell your cells to make molecules called proteins. Proteins perform various functions in your body to keep you healthy. Each gene carries instructions that determine your features, such as eye colour, hair colour and height.
What are chromosomes made out of?
A chromosome is made up of proteins and DNA organized into genes. Each cell normally contains 23 pairs of chromosomes.
How do genes affect your health?
Changes in many genes, each with a small effect, may underlie susceptibility to many common diseases, including cancer, obesity, diabetes, heart disease, and mental illness.
What describes an example of gene therapy?
Gene therapy is the introduction of genes into existing cells to prevent or cure a wide range of diseases. For example, suppose a brain tumor is forming by rapidly dividing cancer cells. The reason this tumor is forming is due to some defective or mutated gene.
What is the difference between an allele and a gene quizlet?
What is the difference between a gene and an allele? A gene is a specific section of a chromosome where the base pairs that code for the characteristic are stored whereas an allele is the actual sequence of the base pairs in the section.
