Concept explainers

Genetic Evolution

Sexual reproduction produces distinct population variations. Heredity determines the traits and qualities to be passed down to the progeny. Over time, this variation within-species is also affected by the process of human evolution. The study of how genetic variation leads to evolutionary changes is known as genetic evolution. If a trait helps an organism to survive and reproduce, it is more likely to be passed down the generations. It is rare that such traits result in a completely distinct set of traits in descendants than the ancestral population; this can result in the emergence of a new species.

THE MOLECULAR GENETICS OF CYSTIC FIBROSIS and of The following is the base sequence of DNA that codes for amino acids 506-510 of the protein that regulates the chlorine channels in the cell membrane. This protein contains a total of 1476 amino acids so this is a small part of the entire gene. DNA Template Strand: 3'TAGTAGAAACCACAA5' 1. What is the minimum number of DNA nucleotides in this whole gene? 2. What is the sequence of bases on the strand of DNA that is complementary to the template strand? 3. What mRNA will be formed from the template strand of DNA? 4. What amino acids will this mRNA code for? 5. If the 6th, 7th and 8th bases in the template strand of the DNA are removed, rewrite the new template strand below. 6. When the template strand of the DNA is changed, this is referred to as a mutation. What kind of mutation is this? 65

The family of a sixth-grade boy in Palo Alto, California, wasinformed by school administrators that he would have to transferout of his middle school because they believed his mutation ofthe CFTR gene, which does not produce any symptoms associatedwith cystic fibrosis, posed a risk to other students at the schoolwho have cystic fibrosis. After missing 11 days of school, a settlementwas reached to have the boy return to school. What ethicalproblems might you associate with this example?

Name Class Date RNA (pages 146-148) | SECTION REVIEW In this section you were introduced to the molecule that helps put the information in DNA to use: ribonucleic acid, or RNA. ANA Iis a nucleic acid that carries information from DNA to the ribosomes, the organelles in which proteins are made. RNA also carries out the process by which proteins are assem- bled from amino acids. RNA is quite similar to DNA in structure. However, there are some important differ- ences. RNA is single-stranded; DNA is dou- ble-stranded. RNA contains the sugar ribose; DNA contains deoxyribose. And RNA has the nitrogenous base uracil; DNA has thymine. In this section you also learned about the process of transcription. Transcription is t process in which part of a DNA molecule is used as a template for the synthesis of a com- plementary strand of RNA. This process is mediated by an enzyme called RNA poly- merase.
