UConn - Biology 1107 Gski Midterm Exam with solutions
Question :Meiosis (short)
Correct answer:In short, is the production of sperm and eggs.
Question :Gametes
Correct answer:Sperm and Eggs
Question :Mitosis
Correct answer:Leads to the ruction of all other cell types (not
sex cells).
Question :Somatic cells
Correct answer:Any cell that is not a sex cell.
Question :Chromosome
Correct answer:Threadlike structure which consists of DNA
wrapped wrapped around proteins.
Question :Histones
Correct answer:The proteins that chromosomes are wrapped
around.
Question :Chromatid
Correct answer:Double-stranded DNA copies in a replicated
chromosome.
Question :Sister chromatids
Correct answer:Chromatid copies that remain attached at their
centromere.
Question :M-phase
Correct answer:Phase of mitosis in which cells are in the
process of separating their chromosomes.
Question :Interphase
Correct answer:Phases that is not M phase, no dramatic
changes here besides the chromosomes uncoiling into long thin structures.
Question :S-phase
Correct answer:A part of interphase in which the genetic
material is copied and then separated in the M phase.
Question :Cytokinesis
Correct answer:The division of cytoplasm into two distinct
cells (this takes place after mitosis or meiosis yet it is its own separate process).
Question :G0 Phase
Correct answer:An eternal form of G phase in which a cell
remains in this state, halted from further division.
Question :Chromatin
Correct answer:The DNA-histone complex that is stretched to
long, thin strands during interphase.
Question :Prophase
Correct answer:The first part of mitosis in which
chromosomes condense into compact structures, spindle apparatuses are formed
Question :Spindle apparatus
Correct answer:Structure that produces mechanical forces.
Question :Function of spindle apparatus
Correct answer:Move replicated chromosomes during early
mitosis and pull chromatids apart in late mitosis.
Question :Prometaphase
Correct answer:Stage after prophase, in which the nuclear
envelope disintegrates, and where microtubules attach to chromosomes at specialized structures called kinetochores.
Question :Kinetochores
Correct answer:Specialized structures where microtubules
attach to chromosomes. Each sister chromatid has one of these.
