Cell Biology & Genetics : Genetic Variation and Mutation

Ultimate sources of genetic variation

• Mutation
• Genetic Recombination
• Natural Selection
• None of the above
• independent assortmen

Sickle Cell Anemia is an example of Point Mutation that caused:

• Frameshift mutation
• Missence Mutation
• Nonsense Mutation
• Silent Mutation
• None of the above

Not true about somatic cell's mutation

• Pass Down to the next generation of cells
• Inherited to the next offspring
• May occurred before birth
• May occurred after birth
• Induced by mutagen

Examples of mutagens

• UV Radiation
• DDT
• Viruses and Bacterias
• None of the above
• All answers are correct

A nonsense mutation is one that:

• Changes an amino acid from one to another
• Deletes segments of RNA
• Adds an additional codon to an RNA transcript
• Creates a premature stop codon
• No Effects
