Question 1: Homozygous Dominant

Answer:

PP

Question 2: Locus

Answer:

Location of a gene on homologous chromosomes

Question 3: Lysogenic Cycle

Answer:

Virus remains latent

Question 4: Metaphase II

Answer:

Chromosomes attach to the spindle, and line up in the middle of the cell

Question 5: Meiosis

Answer:

Reduction division, daughter cell have half the number of chromosomes as parent cells and DNA is different, happens in M Phase, only in sperm and eggs (reproductive cells that make gametes), 4 haploid cells made

Question 6: Heterozygous

Answer:

Two different alleles

Question 7: Gart Gene

Answer:

Causes increased purines in the blood, causes mental retardation

Question 8: Integrase

Answer:

Viral enzyme that cuts open cell's chromosome and pastes the viral DNA inside

Question 9: Telophase II

Answer:

Chromosomes go back into chromatin, nuclear membrane reforms, spindle disappears

Question 10: Heterozygous

Answer:

Pp

Question 11: Chiasma

Answer:

Site of crossover

Question 12: Viruses

Answer:

Not living, don't replicate or carry out metabolism by themselves, must be taken up by a living cell to replicate, smaller than bacteria, can infect many different species, have a capsid and use nucleic acid as the genetic material (DNA or RNA)

Question 13: Tay Sachs

Answer:

Develop neurological problems, seizures, death by age 5

Question 14: Prophase

Answer:

Nuclear membrane breaks down, Chromatin is condensed into chromosomes, spindle forms

Question 15: Testcross

Answer:

cross an organism with the dominant phenotype with an organism with the recessive phenotype.

Question 16: Genotype

Answer:

Genetic composition of an organism

Question 17: Turner Syndrome

Answer:

Only one X Chromosome

Question 18: Jacob Syndrome

Answer:

XYY, taller, lots of acne, lower intelligence level

Question 19: Diploid

Answer:

Has two copies/alleles of each gene

Question 20: Viral envelope

Answer:

membrane surrounding capsid, membrane from host cell with spikes of viral protein

Question 21: True breeding

Answer:

Homozygous (two of the same alleles)

Question 22: Chorionic Villi Sampling

Answer:

Removes cells of the chorionic villi

Question 23: Interphase

Answer:

DNA in chromatin form, nuclear membrane surrounding DNA, centrosomes have replicated

Question 24: Phenylketunuria (PKU)

Answer:

Can't metabolize Phenylalanine, leads to mental retardation if not detected early and put on special diet

Question 25: Lytic Cycle

Answer:

Bacteriaphage are released by lysing bacterial cells

Question 26: Huntington's Disease

Answer:

Dominant autosomal disease, severe neurological problems, eventually death

Question 27: Anaphase I

Answer:

Homologous chromosome pairs separate, each chromosome goes to opposite pole , cell elongates, cytokinesis begins

Question 28: Anaphase

Answer:

Chromosomes split apart, chromosomes go to opposite ends of the poles, cell elongates, cytokinesis begins
