At the end of mitosis, each daughter cell has 1.the same number and kinds of chromosomes as in the parent cell. 2.the same number but different kinds of chromosomes as in the parent cell. 3.twice the number of chromosomes as in the parent cell. 4.half the number of chromosomes as in the parent cell.
Chromosomes are made up of 1.nuclear RNA. 2.DNA and protein. 3.protein. 4.DNA.
The two main stages of cell division are 1.mitosis and interphase. 2.synthesis and mitosis. 3.mitosis and cytokinesis. 4.cytokinesis and interphase.
Cancer is a disorder in which some cells have lost the ability to control their 1.Size. 2.Weight. 3.Mass. 4.Growth.
In mitosis, sister chromatids separate during 1.Metaphase. 2.Prophase. 3.Anaphase. 4.telophase.
In the cell cycle, DNA replication occurs during the 1.S phase. 2.G 1 phase. 3.G 2 phase. 4.M phase.
Your skin replaces the cells that it is continually losing by using the process of: 1.Transduction 2.Mitosis 3.Meiosis 4.lysis
The stage of the cell cycle where each chromosome is composed of two chromatids in preparation for mitosis. 1.G1 2.S 3.M 4.G2
Beginning with mitosis, what are the other parts of the cell cycle in order in which they occur? 1.cytokinesis, G 1, S, G2 2.cytokinesis, S, G 1, S, G2 3.S, cytokinesis, G 1, S, G2 4.S, G 1, S, G2
Beginning with interphase, what are the phases of mitosis in order in which they occur? 1.telophase, anaphase, metaphase, prophase 2.anaphase, metaphase, prophase, telophase 3.prophase, anaphase, metaphase, telophase 4.prophase, metaphase, anaphase, telophase
Which sequence of the cell cycle is common to eukaryotes? 1.G1, G2, S, M, cytokinesis 2.G1, M, G2, S, cytokinesis 3.G1, S, M, G2, cytokinesis 4.G1, S, G2, M, cytokinesis
The stage of the cell cycle where the cell is preparing to begin DNA replication is called: 1.G1 2.G2 3.S 4.M
Prior to cell division, each chromosome replicates or duplicates its genetic material. The products are connected by a centromere and are called: 1.Sister chromosomes 2.Homologous chromosomes 3.Sex chromosomes 4.Sister chromatids
The first stage of mitosis when chromosomes start becoming visible in the microscope is called: 1.Anaphase 2.Prophase 3.Telophase 4.metaphase
In which phase do the chromosomes align on a plane in the center of the cell? 1.Prophase 2.Metaphase 3.Anaphase 4.telophase
What occurs during anaphase? 1.The mitotic spindle begins to form. 2.The chromosomes align on a plane in the center of the cell. 3.The sister chromatids separate. 4.The mitotic apparatus disassembles.
What is the part of the chromosome that joins the two chromatids? 1.Kinetochore 2.Centriole 3.Centromere 4.mitotic spindle
Which of the following is true of mitosis in a diploid cell? 1.It results in 2 haploid daughter cells. 2.It involves transcription of the cell's DNA. 3.It results in daughter cells who are genetically identical, but physically smaller, than the original cell.
Which stage of mitosis is seen in the pictured cell? 1.Prophase 2.Metaphase 3.Anaphase 4.Telophase
What stage of mitosis is this cell in? 1.Prophase 2.Metaphase 3.Anaphase 4.Telophase
Place the pictures in the correct chronological order. 1.1,2,3,4 2.2,4,1,3 3.2,4,3,1 4.4,2,1,3
The following is a picture of what phase of nuclear division: 1.Prophase 2.Metaphase 3.Anaphase 4.Telophase
