Bio 351 Exam 1 2025 Questions and
Answers 100% Pass
Chromosome types - ✔✔metacentric, acrocentric, telocentric
Metacentric chromosome - ✔✔centromere in middle
Acrocentric chromosome - ✔✔centromere close to end
Telocentric chromosome - ✔✔centromere at telomere
Karyotype - ✔✔drawing/photo of chromosomes in a cell
Usually during cell division
usually stained
What do Karyotypes tell us? - ✔✔number of chromosomes in a species (invariant)
2 types of eukaryotic cells (haploid/diploid)
Haploid (n) - ✔✔one copy of each chromosome
Diploid (2n) - ✔✔two copies of each chromosome
Haploid cell - ✔✔
Diploid cell - ✔✔
Asexual reproduction - ✔✔mitosis
Mitosis - ✔✔occurs in reproduction of simple organisms

, growth and tissue maintenance
Stages of mitosis - ✔✔interphase, prophase, metaphase, anaphase, telophase
Interphase (mitosis) - ✔✔cell grows, chromosomes replicate
Prophase (mitosis) - ✔✔chromosomes condense
Metaphase (mitosis) - ✔✔chromosomes line up at equator of cell
Anaphase (mitosis) - ✔✔sister chromatids separate to opposite ends of cell
Telophase & Citokenesis (mitosis) - ✔✔cell divides
Meiosis - ✔✔a reduction division that results in the formation of 4 haploid gametes
from a diploid cell (reduction division)
Steps of Meiosis - ✔✔Interphase, Prophase 1, Metaphase 1, Anaphase 1, Telophase 1,
Prophase 2, Metaphase 2, Anaphase 2, Telophase 2
Interphase (meiosis) - ✔✔genetic material is dupliated
Prophase 1 (meiosis) - ✔✔chromosomes condense
homologous chromosomes pair up with one another (synapsis)
Crossing over occurs during synapsis
Chiasma - ✔✔location of crossing over
Metaphase 1 (meiosis) - ✔✔Chromosomes line up at the equator.
Anaphase 1 (meiosis) - ✔✔homologous chromosomes separate the opposite poles
Prophase 2 (meiosis) - ✔✔chromosomes stay condensed
Metaphase 2 (meiosis) - ✔✔Chromosomes line up at the equator.
Anaphase 2 (meiosis) - ✔✔sister chromatids separate
