1.What does it mean that DNA is genetic material ?
2.what is the difference between Gene and Allele and give an example of multiple Alleles for a gene
1. DNA (Deoxyribonucleic acid) being the genetic material means that it carries and transmits genetic information from one generation to the next in all living organisms. It contains the instructions that determine the development, functioning, and characteristics of an organism.
2. A gene is a specific segment of DNA that contains the instructions for building one or more proteins. Genes are the fundamental units of heredity and determine the traits or characteristics of an organism. For example, the gene responsible for eye color provides instructions for the production of pigments that determine whether an individual will have blue, brown, or green eyes.
Alleles, on the other hand, are alternate forms or variations of a gene. They occupy the same locus or position on a chromosome but can have slightly different sequences. Alleles can produce different versions of a trait. For instance, the gene for blood type has three alleles: A, B, and O. A person can have two alleles for their blood type, one from each parent, and the combination of these alleles determines their blood type (e.g., AA, AB, BB, OO).
