Third Quarter Biology Review
1) Compare and contrast DNA and RNA structure.
2) Define these processes: (what happens in each?)
Replication:
Translation:
Transcription:
3) Sketch a nucleotide, labeling the three main parts.
4) What are the complementary nitrogenous bases?
5) Explain how a DNA sequence would be translated into an RNA codon and
then into a particular amino acid:
EX. DNA= TAC would be ___ ___ ___ in m RNA or the amino acid ____________.
6) Compare and contrast meiosis and mitosis.
7) Which of the above processes forms haploid and which forms diploid cells?
8) What differences do sex cells or gametes have from autosomes or body cells?
9) Male gametes = __________________; female gametes= __________________
10) Be able to recognize both forms of cell division from diagrams.
11) In a heterozygous cross, what would the expected phenotypic ratio be?
12) Define mutation:
13) How does a gel electrophoresis show who is most closely related to each
other?
14) Possible Blood genotypes for all four groups. Given information be able to
deduce familial relationships using Punnett squares.
15) Genetic diseases such as Down Syndrome, hemophilia, sickle cell,
Phenylketonuria, and Tay-Sachs.
16) Understand how sex-linked recessives such as colorblindness are inherited.
17) Be able to interpret a pedigree.
18) Explain the process of recombinant DNA or genetic engineering:
19) How are restriction enzymes used for this process?
20) Be familiar with the Human Genome Project.
21) What reproductive process creates more genetic variation?
22) Explain test crosses. How do you determine genotypes of an unknown
organism?
23) From evolution, define extinction, competition and speciation
24) What is a niche?
25) Explain abiogenesis, biogenesis, endosymbiosis and natural selection.
26) What causes resistance?
27) Compare and contrast mimicry and camouflage.
