Lab Quiz 2 Flashcards
What holds two sister chromatids together?
A centromere
DNA replication occurs during _________.
Interphase
A rod-shaped body in the nucleus that is seen during mitosis and meiosis and that contains DNA
Chromosome
An organelle found inside the nucleus; composed largely of RNA for ribosome formation
Nucleolus
Microtubule structure that brings about chromosome movement during cell division.
Spindle
The two identical parts of a chromosome following DNA replication.
Chromatids
The central microtubule-organizing center of cells consists of granular material (2 centrioles in animal cells)
Centrosome
A constriction where duplicates of a chromosome are held together.
Centromere
Duplicates of a chromosome are called what?
Sister chromatids
A short, cylindrical organelle in animal cells that contain microtubules and is associated with the formation of the SPINDLE during cell division
Centriole
Short, radiating fibers produced by centrioles; important during mitosis and meiosis.
Aster

No, there is only synapsis in MEIOSIS
What are homologous pairs?
They contain genes, they come together to become a cell that will perform the same function / trait
