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?
Chromosomes:Genetically normal human beings have 23 pairs of chromosomes, which makes 46 chromosomes in total. Two of these chromosomes are called sex chromosomes.Answer and Explanation: Most women have two X chromosomes. This differs from men, who have one X and one Y chromosome. However, ...
What does the nucleus do in the sperm cell? What must the entry of a sperm nucleus into an oocyte be preceded by? What does DNA do in a plant cell? What part of a cell contains chromosomes? What are rod-shaped structures in the cell nucleus that contain genes called?
Genes are contained in chromosomes. These in the cell nucleus. A single chromosome contains hundreds to thousands of genes. Every normal human cell comprises 23 pairs of chromosomes that mean a total of 46 chromosomes. A trait is any gene-determined characteristic. It is ofte...
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...
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...
Chromosomes are thread-shaped structures that are found in cells of living organisms and that contain DNA, a nucleic acid that contains the genetic instructions for those organisms. A chromosome disorder can be caused by an alteration in the number of chromosomes in a cell's nucleus or by an ...
a copy of itself), transcription (messenger RNA being synthesized from a DNA template) and DNA repair to occur. Just as you may need to take apart a household appliance to repair a problem or replace a part, the loosened structure of chromosomes in the interphase (i.e., between cell ...
History of fetal aneuploidy (abnormal number of chromosomes in a cell) in previous pregnancies Certain cases of male sterility, such as those when the semen sample is collected directly from the epididymis or the testis. Like with any other treatment, the use of PGD has somelegal limitationsthat...
What part of the sperm cell contains chromosomes? What part of a sperm cell contains chromosomes? How many chromosomes are in human sex cells? What are autosomes cells? What is a diploid cell? Do somatic cells produce diploid cells?
