Questions and Answers
Explain how an organism's phenotype can be influenced by both its genotype and the environment.
Explain how an organism's phenotype can be influenced by both its genotype and the environment.
An organism's phenotype is determined by the interaction of its genotype (genetic makeup) and the environment. The genotype provides the blueprint, while the environment can modify gene expression and thus alter the resulting phenotype.
Describe the process of transcription, including the roles of RNA polymerase and the template strand.
Describe the process of transcription, including the roles of RNA polymerase and the template strand.
Transcription is the process where RNA polymerase uses DNA as a template to synthesize a complementary RNA molecule. RNA polymerase binds to the promoter region of a gene and uses the template strand to create mRNA.
Outline the key differences between mitosis and meiosis in terms of the number of cell divisions and resulting daughter cells.
Outline the key differences between mitosis and meiosis in terms of the number of cell divisions and resulting daughter cells.
Mitosis involves one cell division and results in two diploid daughter cells genetically identical to the parent cell. Meiosis involves two cell divisions and produces four haploid daughter cells with genetic variation.
Explain how gel electrophoresis is used to separate DNA fragments and how the results can be interpreted.
