GUARANTEED TO PASS CONCEPTS
◉Diploid number in humans: Answer: 46
◉Which of the following is correct?
Sister chromatids are held together by cohesion.
Chromosome bodies are responsible for the formation of spindle fibers.
In metaphase, centromeres are dispersed throughout the nucleus.
Answer: Sister chromatids are held together by cohesion.
◉TRUE/FALSE:
Genetic information can be transferred between bacteria on a single-
stranded RNA molecule called a plasmid. Answer: False
◉TRUE/FALSE:
A chromosomal aberration is an alteration to the chromosome that
results in
, a change to the total number of chromosomes, deletions or additions to
the chromosome, or even complete rearrangement of chromosomal
segments. Answer: True
◉TRUE/FALSE:
Most scientists believe that the biggest driver of a cancer phenotype is
the ability of cancer cells to avoid apoptosis. Answer: False
◉Explain briefly how the idea of epigenesis and preformation directly
contradict each other: Answer: Preformation postulated that a fertilized
egg contained a miniaturized version of a tiny human, called
homunculus. Epigenesis directly contradicted that theory by stating
that a fertilized egg undergoes a series of developmental events that
eventually form a human.
◉Which of the following statements is correct?
The X chromosome is much larger than the Y chromosome.
The X and Y chromosomes share no homology.
The X chromosome is the driving determinant for sex of an offspring.
Incorrect segregation of X and Y chromosomes (for instance a female
with XXX or X genotype) is always embryonic lethal. Answer: The X
chromosome is much larger than the Y chromosome.
