During interphase, the chromosomes are not visible using a light microscope. Why would this be important for a cell? What is the significance of meiosis in terms of the genetic content of the cells produced? How do chromatin and chromosomes compare to one another?
What is the total number of chromosomes in each daughter cell at the end of meiosis II? A cell with a diploid number of 24 fails to undergo cytokinesis while performing mitosis so that the daughter cells do not form. How many chromosomes will be in the resulting cell A. 96 B. 24 ...
The life of a human being begins as a single celled zygote. The information presents in the chromosomes in this cell is what determines the characteristics of this human being. Each cell in the body of a male contains one X chro mosome and one Y chromosome (XY). Read the passage and...
A cell can replicate itself independently. Hence, they are known as the building blocks of life. Each cell contains a fluid called the cytoplasm, which is enclosed by a membrane. Also present in the cytoplasm are several biomolecules like proteins, nucleic acids and lipids. Moreover, cellular...
Through microscopic techniques, the concentration of chromosomes (in the nucleus or the nucleoids) causes parts of the cell to have a dense, dark appearance which represents the regions of the cell that contains DNA material. In organisms with several chromosomes (e.g. human beings have 23 pa...
Contains all the 23 chromosomes of the sperm cell, that is, half the genetic information of the future embrion. This is the only part of the sperm cell that enters into the egg cell. As such it is the most important part of the spermatozoon. Its purpose is to fuse with the nucleus of...
Submit What would be the number of chromosomes in the cells of the aleuron layer in a plant species with 8 chromosomes in its synergids? A24 B32 C8 D16Submit What would be number of chromosomes in aleurone layer if megaspore mother cell contains 10 chromocomes View Solution The number of...
Being thicker than the primary wall, the secondary wall also contains most of the cellulose and thus the majority of carbohydrates with regards to biomass. For this reason, it's not only a component of wood but also nutrition for various organisms. ...
Each sex chromosome is composed of two pseudoautosomal regions (PAR1 and PAR2), which are conserved homologous sequences on the X and Y chromosomes, in addition to a sex chromosome-specific region which contains a greatly increased amount of genetic material on the X chromosome relative to the...
A chromosomally normal zygote has 23 pairs of chromosomes. At the time of fertilization, it has only one cell (made when the sperm cell combines with the egg cell). "The genetic information in these cells then causes the zygote to start dividing," says Dr. Richlin. Essentially, the single...
