Why is DNA replication necessary before cell division occurs? When do cells duplicate their DNA? Why is DNA required in a living system? Why is DNA so important? When does the replication of DNA occur? Explain the mechanism by which DNA is replicated. ...
Describe some of the mistakes that can occur during DNA replication and how they are repaired. How does DNA ultimately control the functioning of cells? How/why can mutations in DNA disrupt proper functioning? Briefly describe the consequences of incorrect DNA repl...
"After fertilization, the fertilized egg (now called a zygote) travels through the fallopian tube and undergoes several rounds of cell division as it moves towards the uterus," explainsLora Shahine, MD, FACOG, a reproductive endocrinologist and program director of Pacific NW Fertility in Seattle....
It is well known that proteins are highly abundant in nucleoli, where rRNA synthesis and ribosome formation occur, so the protein-rich spots we found are probably nucleoli. The spectra of components 3–5 (Fig. 2a–3–5) show no prominent Raman signature. The assignment of component 5 is...
Diploid Cell: A diploid cell is a basic unit of life that contains two copies of genetic information within its nucleus. Each of these copies come from the parents of that cell, one from the mother and one from the father cell.

The combination of changes in cell behaviour, structure and function that occur upon cellular senescence. For most cell types, these changes include an essentially irreversible growth arrest, resistance to apoptosis and many alterations in gene expression. Oncogene A gene that contributes to the maligna...

If cell divisions occur in a distributed fashion throughout this region, then a pure cellular oscillator mechanism does not produce any segmentation. Under these circumstances, positional information in the form of a morphogen gradient is required for segmentation....
How is the process of cell division called? What cells don't take part in cell division? What is the stage of a cell's life cycle in which the cell spends most of its time? How long does cell division occur? What portion of its life time does a cell spent in s...
