Meiosis vs. Mitosis Genetics Quiz

During meiosis, chromosomes replicate once but nuclei divide once.

Mitosis involves one round of chromosome replication and one round of nuclear division.

Daughter cells produced in meiosis are haploid (n).

Genetic approaches have shifted focus from analyzing single genes to entire networks.

The discovery of genes causing disease variations is slowing down.

Understanding biological complexity using genetic approaches is progressing slowly.

Haploid cells have two matching sets of chromosomes.

Phenotype refers to the actual alleles present in an individual.

Unicellular organisms do not have a nucleus.

There are 64 triplet codons that represent 20 amino acids.

The genetic code is not degenerate.

Rapid changes in regulatory networks can impact the genotype of an individual.

During polypeptide synthesis, the release factors help in the addition of more amino acids to the chain.

Transition mutations are more common than transversion mutations in genetic variations.

All mutations, whether deleterious, advantageous, or neutral, have a selective advantage to the organism.

Insertions or deletions of bases can introduce frameshift mutations in the genetic code.

Mitosis and meiosis are both involved in cell division processes but only mitosis is responsible for genetic diversity.

DNA replication occurs during the S phase of the cell cycle, whereas metabolism primarily happens during the G1 phase.
