How many daughter cells are produced in meiosis? How many chromosomes are visible at the beginning of mitosis? How many sister chromatids are found in a human somatic cell nucleus during mitosis? How many daugh
How many chromosomes do monkeys have? How many chromosomes does the family Ursidae have? How many chromosomes are found inside the nucleus of every human cell except egg and sperm cells? In humans, how many chromosomes are in each cell after mitosis?
coli bacterium, cells of plants and animals have chromosomes that hold the DNA strands. Humans have 23 pairs of chromosomes, for a total of 46 chromosomes. Fruit flies have five pairs. Dogs have 39 pairs, and some plants have as many as 100. Chromosomes come in pairs. Each chromosome is...
Topoisomerase activity is indispensible to cells, but requires the transient breakage of DNA strands. This property has been exploited, often for significant clinical benefit, by various exogenous agents that interfere with cell proliferation. Despite decades of study, surprising findings involving ...
Mitosis is important to multicellular organisms becauseit provides new cells for growth and for replacement of worn-out cells, such as skin cells. Many single-celled organisms rely on mitosis as their primary means of asexual reproduction.

Complex organisms, like plants and animals, have 50,000 to 100,000 genes on many different chromosomes (most humans have 46 chromosomes). In the cells of these organisms, the DNA is twisted around bead-like proteins called histones. The histones are also coiled tightly to form chromosomes, wh...
DNA repair can occur at several stages of the cell cycle but cells are mostly arrested in the G1/S and G2/M phases. If damage occurs due to replication errors, an arrest can also occur in the S-phase or later in mitosis. FIGURE 2. DNA repair mechanisms at the molecular level. I....
How do somatic cells get created from the gametes? What would happen if synapsis did not occur in meiosis? Where does meiosis take place? Why don't chromosomes pair up in mitosis? Is meiosis a part of the cell cycle? How many chromosomes are in a cell at the beginning of meiosis?
After it divides by mitosis, how many chromosomes will there be in each cell?What is the number of chromosomes in a somatic cell? And how many chromosomes are there in a gamete (sex cell)?A parent cell containing 32 chromosomes will produce two daughter cel...
