BIO 1050 EXAM 3 QUESTIONS WITH
VERIFIED ANSWERS
In anaphase I of meiosis what is moving together towards the centrosomes at the poles
of the cell? - Correct Answers -pairs of sister chromatids
What are the correct names, in order for the stages of mammalian development? -
Correct Answers -egg, zygote, blastocyst, embryo, fetus, infant
A pair of sister chromatids - Correct Answers -is made when one DNA double helix is
copied during S phase
Which of the following is MOST likely to prevent fertilization and/or implantation? -
Correct Answers -abstinence
Which of the following occurs during BOTH cell division in prokaryotes and the mitotic
cell cycle of eukaryotes? - Correct Answers -the DNA duplicates

spindles during - Correct Answers -prophase and/or prometaphase
Prokaryotic cells divide by - Correct Answers -binary fission
Assume no mutations or crossing over events for this question. Homologous
chromosomes - Correct Answers -have different alleles
