Whare two different types of nucleic acids? What is a nucleotide? What are the parts of a nucleotide?

 

 

            Describe how the basic structure of DNA differs from that of RNA. What bases are found in each? What kind of sugar is found in each type of           nucleic acid? Which is double stranded?

Describe complementary base pairing as it occurs in DNA and in RNA. What would the complementary RNA base pair sequence be if the DNA sequence was TACTGCACGTGA? What would the complementary DNA base pair sequence be if the DNA sequence was ATGCAGTGCTAT?

 

            What enzyme makes new strands of DNA during DNA replication?

What enzyme makes new strands of RNA during transcription?

            How does transcription differ from translation? Where in a cell does each occur?

What is the function of the ribosomes in cells?

            With regard to the role they play in translation, how does tRNA differ from mRNA? Which type of RNA carries amino acids?

What is a codon? What is an anticodon? What is the genetic code? What is a start codon? What is a stop codon?

            Briefly, in simple words, describe how translation occurs on ribosomes.

What is a mutation? How could a mutations lead to the formation of a genetic disease? (think about what a gene is used for and how mutations would affect proteins, e.g. sickle cell anemia)

 

 

What is a population? With regard to populations of organisms, what causes evolution of a

population? What is a gene pool?

 

What is natural selection and how does it differ from artificial selection? What is reproductive fitness? Who first hypothesized the process of natural selection?

 

What is the fossil record? Why is it useful for studies of evolution?

 

What was incorrect about Jean Baptiste de Lamarck’s theory of evolution?
