What are gametes formed by? How many chromosomes are in each sperm? Discuss the stages of mitosis. Define homologous chromosomes in your own words. Briefly describe, in your own words, how the single cell formed at fertilization differentiates into different types of cells. ...
Answer and Explanation: During S phase, the DNA in a cell is replicated. Since there are normally 46 chromosomes, and this number is doubled after S phase, human cells now have 92 chromosomes.Insert context header here:Insert context explanation here......
To solve the question regarding the number of chromosomes in a diploid cell at different phases of the cell cycle, we can follow these steps:Step 1: Understand the terms - Haploid (n): A cell with one set of ch
Caprifoliaceae of presumably related genera [Abelia and Depelta (Linnaeeae); Lycesteria and Lonicera (Caprifolieae); Weigela (Diervilleae)] reveals similarities in some karyological features such as structure of interphase nuclei, chromosome size, and condensation behaviour of chromosomes during mitotic...
During mitosis, many proteins dissociate from chromatin and transcription shuts down. This may favour a silent PRE but challenge an active one. Several PcG and TrxG proteins remain bound to mitotic chromatin and may 'bookmark' silent and active states. Many PcG and TrxG target genes are dynami...
The main reason why there is no detailed structural information about chromatin in interphase is that there are no direct experimental methods to investigate the structure. While light microscopes suffice to visualize full cell nuclei and total chromosomes, they are limited in spatial resolution and do...

During mitosis, how many pairs of homologous chromosomes are there present during interphase? An empty cell exhibited 11.5 interference fringes in the region of 1050 to 1580 cm^{-1}. What was the path length of the cell? What is a phase diagram? What is plotted on the x-axis of a phas...
Figure 4: Adherently grown epithelial cells (MDCK) were cultured on coverslips, fixed, and nuclei stained with Hoechst 33342. Most cells showed interphase DNA staining, but some cells showed chromosome condensation and these chromosomes segregated in mitosis (asterisks). Microscopic examination was per...
Chromosomes:A chromosome is a single molecule of DNA that stores genetic information which can be used to produce functional proteins. Chromosomes can be linear, like in humans, or circular, like in bacteria.Answer and Explanation: There are 46 chromosomes in each human cell. More specifically, ...
