Warning this is a lot of info and questions!

describe the role and structure of the chromosome (dna, chromatin, centromere).

describe and identify what occurs during the different events of the cell cycle (mitosis-prophase, anaphase metaphase, telophase, interphase, cytokinesis).
describe stem cells and understand that cells differentiate to produce multiple cell types in multicellular organisms.
describe the role of mitosis in living things including growth, repair and reproduction.
describe the structure of dna using the words double helix, adenine, thymine, guanine and cytosine.
describe the steps of dna replication.
distinguish between dna and rna.
describe amino acids, proteins, ribosomes, enzymes.
describe the purpose, location and outcomes of transcription and translation.
summarize what happens when mutations occur and how that affects the production of functional proteins. (including how environmental factor can damage dna making it more susceptible to replication mistakes.)
recite how repressor proteins block transcription.
repressor proteins block transcription by blocking the one part of dna that allows the ability to start transcription.
describe homologous chromosomes, crossing over, haploid, diploid, segregation, meiosis, gamete, independent assortment, tetrad, nondisjunction

describe alleles, genotype, phenotype, genetic probability, dominant, recessive, pedigree
restate the stages of meiosis.
state an example of how the environment can affect the expression of a trait.
describe the evidences for evolution using the words fossils, artificial and natural selection, biogeography, adaptation, fitness, homologous structures, analogous structures, and vestigial structures.
recall examples of evolution from several lines of evidence.
an alligator compared to a crocodilian from prehistoric times, the hip and shoulder bones compare to each other.
state the sources of genetic variation (mutation, sexual recombination.)

define a species and reproductive isolation.

Neelaredoxin is a 15-kda protein that is a gene product common in anaerobic prokaryotes. it has superoxide-scavenging activity, and it is constitutively expressed. in addition, its expression is not further induced during its exposure to o2 or h2o2 (silva, g., et al. 2001. j. bacteriol. 183: 4413–4420). which of the following statements best describes neelaredoxin synthesis? a-neelaredoxin is produced at all times; levels are constant even when exposed to o2 or h2o2.b-neelaredoxin is produced at all times; exposure to o2 or h2o2 increases expression.c-neelaredoxin is produced at all times; exposure to o2 or h2o2 decreases or prevents expression.d-neelaredoxin is only produced when there is exposure to o2 or h2o2.
