Investigation Dna Proteins And Mutations Answer Key Pdf
Deoxyribonucleic Acid or DNA is a complex long molecular chain that contains genetic information in living organisms. It is composed of nitrogenous bases, phosphates, and sugars arranged in a sequence that makes up genes. DNA is the blueprint that determines the physical traits and characteristics of living organisms, including humans. DNA is found in every living cell of the body and is responsible for passing genetic information from one generation to another.
What are DNA Proteins?
Biological molecules that are essential to various cellular functions including replication, transcription, and translation of genetic information are called proteins. Proteins are composed of amino acids that are arranged in a specific sequence to form a 3-dimensional structure that determines its function. Proteins are responsible for carrying out many necessary functions in the body, including catalyzing chemical reactions, forming structural components of cells, and transporting molecules around the body.
What are Mutations?
Mutations refer to changes in the DNA sequence that occur spontaneously, or due to environmental factors. These changes can alter the function of the protein encoded by the gene. Mutations can be beneficial, harmful, or have no effect at all. Beneficial mutations provide an advantage to the organism, whereas harmful mutations can cause diseases or disorders. Mutations can also occur in non-coding regions of DNA that regulate gene expression.
