,During _____________, pairs of sister chromatids become attached Prometaphase
to kinetochore microtubules which emanate from opposite
poles of the cell
The primary purpose of mitosis is to... Distribute the replicated chromosomes into the two daughter cells
Select all of these that are events of telophase I of meiosis -The nuclear membrane reforms in most species
-Sister chromatids have reached their respective poles
Consider an organism that has three pairs of chromosomes. At Three chromosomes and six chromatids
the start of meiosis II, each cell would have
After replication, the two copies of a chromosome are called sister chromatids
______________ _________________
All the fallowing occur in mitosis except: Pairing and synapsis of homologous chromosomes occurs
-Sister chromatids separate, and move to opposite poles
-Chromosomes condense, and nuclear envelope breaks down
-Chromosomes align on the metaphase plate of the cell
-Pairing and synapsis of homologous chromosomes occur
-Kinetochorses begin attaching to spindle fibers
In this figure, label A points to the _____________ ____________, which Synaptonemal complex; Chiasma
holds the bivalent together, while label B shows the
_______________, which is the connection that results from a
crossing over
Select all of the following events that occur during prophase: -The mitotic spindle begins to form
-The mitotic spindle begins to form -The chromatids become condensed
-The two centromeres are replicated -The nuclear membrane begins to dissociate into small vesicles
-The chromatids become condensed -The nucleolus becomes less visible
-The nuclear membrane begins to dissociate into small
vesicles
-The nucleolus becomes less visible
During ______________ of meiosis, the pairs of sister chromatids (or Telophase I
dyads) reach the opposite poles of the cell, where, in most
cases, they decondense
, Once a chromosome replicates, it forms a pair of Sister chromatids
A haploid cell is represented by 1n and a diploid cell by 2n. A set of chromosomes
The n refers to
In _____________ of meiosis, the bivalents (which are also termed Metaphase I
tetrads) are aligned along the center of the cell
Which of the following best describes the outcome of meiosis 2n-->1n
in humans?
-2n-1n
-1n-1n
-2n-2n
-1n-2n
Most bacterial cells divide by Binary fission
The eukaryotic cell cycle is composed of Four phases G1, G2, S, and M
In actively dividing cells, the G1, S, and G2 phases are Interphase
collectively known as
Consider a diploid cell with 2n=6. this cell is shown in which Anaphase I of meiosis
phase of cell division (structures migrating to opposite poles
of are pairs of sister chromatids (dyads) and are not individual
chromosomes)
Chromosomes are replicated during the ) _____________ phase of S
the cell cycle
The centromere is A region of the chromosome where the sister chromatids join
The _______________ is a protein-complex that is bound to the Kinetochore
centromere, and which plays a key role in the separation of
chromosomes during cell division
