Mitosis
Question | Answer |
---|---|
___________- takes place in the cells in the human body | mitosis |
Body cells are also called _____________ | somatic cells |
This type of cellular division produces daughter cells that are identical to the parents | Mitosis |
Uncoiled strands of DNA | Chromatin |
Made of coiled DNA strands and contain genes | chromosomes |
segments of DNA on a chromosome that code for a certain trait | genes |
one part of a duplicated chromosome | chromatid |
_____________ attaches sister chromatids to each other | centromere |
chromosome pairs that are similar in structure and contain information for the same genes | homologous chromosomes |
each somatic cell has _______ chromosomes | 46 |
cells that contain all homologous pairs of chromosomes are _____________ cells | diploid |
In this stage, chromosomes( in the form of chromatin) and organelles replicate | interphase |
chromatin coils into chromosomes. Each In this stage,chromosome is now made up of 2 chromatids joined by a centromere | prophase |
In this stage,nuclear membrane disappears | prophase |
In this stage,centrioles and spindle fibers form | prophase |
In this stage,chromosomes move to the center of the cell | metaphase |
chromosomes divide and chromatids separate | anaphase |
In this stage,chromatids are pulled to opposite sides by spindle fibers | anaphase |
In this stage,centrioles and spindle fibers disappear | telophase |
In this stage,chromatids unwind back into chromatin | telophase |
In this stage,nuclear membrane reforms | telophase |
In this stage,cytoplasm in parent cell divides. 2 new cells are formed | cytokinesis |
There are ____ pairs of homologous chromosomes in each somatic cell. | 23 |
information for these genes may be different | homologous chromosomes |
At the end of mitosis two daughter cells are produced which are identical to the parent cell. The DNA is the same. | True |
