Bio chap 11 Flashcards
What is the function of histone proteins
organize DNA in eukaryotic chromosomes
What cellular process is responsible for the increase in protein content associated with the gap phases of the cell cycle?
gene expression, protein synthasis
What is the role of the protein FtsZ?
It is involved in the attachment of DNA to the plasma membrane.
Predict what would happen to the daughter cells if the G1 phase of the parent cell is shortened?
The cells would be smaller than normal.
What happens to CDK in the absence of cyclin
it is inactive
A cell that is not actively dividing is in what phase of the cell cycle
G0
Synapsis is best described as
the alignment of homologous chromosomes in prophase 1
Why don’t plant cells use a contractile ring to divide their daughter cells?
A contractile ring can’t “pinch” a cell wall.
The division of the cell’s cytoplasm in a eukaryotic cell is known as:
cytokineses, and mitosis
Which of the following is not true regarding the protein CDK?
The levels of CDK change with the cell cycle.
Why would a compound that interferes with bacterial cell wall synthesis be useful for the treatment of an infection?
It would limit the spread of the infection.
What properties are associated with a malignant cancer
fast growing
invades surrounding tissue
metastatic
The prokaryotic protein FtsZ is evolutionarily related to eukaryotic tubulin. What does this mean?
The gene sequence for FtsZ is similar to tubulin.
The amino acid sequence for FtsZ is similar to tubulin.
The overall protein structure of FtsZ is similar to tubulin.
At what step in meiosis do the daughter cells become haploid?
anaphase 1
What is the function of the centromere?
to attach the sister chromatids to each other
