If a cell with 16 chromosomes undergoes mitosis, how many chromosomes will each daughter cell have? If a cell has 30 chromosomes before mitosis, how many does each daughter cell have afterward? How many chromosomes does each daughter cell have? How many chromosomes do ...
Where in the cell are chromosomes located? What is the importance of the inner cell mass of the cleaving embryo? Explain. How many chromosomes does a human cell contain? What determines the heredity of the 46 chromosomes? In eukaryotic cells, DNA is packaged with proteins into structures called...
A cell line called Nagoya-78 has been established from a human salivary gland mixed tumor. The cytoplasm of the cells contain much glycogen but little acid polysaccharide and mucin. The ultrastructure of the cells exhibit epithelial characteristics with desmosomes, and no virus particles are present...
And if you stretch them out, you'll find they contain certain genes, certain sequences of DNA that help determine how the cells of the body will develop.When researchers looked really carefully at the DNA in chromosomes, though, they were amazed—we all were—to find that only a fraction...

6, the kar9-αβγ− triple interface mutant allele was lethal or nearly so in combination with bik1Δ at all tested temperatures (25–35 °C); in these cells the Kar9 network was not functional. Mutating any of the α, β or γ interfaces alone, or removing Bik1 individually, ...
Analysis of several cells showed an average of 199 ± 46 spots. Given that the spots had varying fluorescence intensity, we cannot rule out each spot containing a varying amount of DNA18, i.e., a different number of chromosomes or chromosomes of varying sizes. Based on previous ...
All piggyBac insertion sites identified by next-generation sequencing were widely distributed over 31 chromosomes. The X-axis indicates the chromosome. The Y-axis indicates the density of unique insertion sites. To construct a mutated Marc145 cell library, approximately 5 × 107 cells were co...
Spermatazoa are the male gamete,meaning they are the cells that fuse with the egg in fertilization giving rise to the embrion and future baby.
The onset of mitosis is defined by the start of chromosome condensation that converts the long interphase chromosomes into units amenable for being properly segregated to the daughter cells. Chromatin condensation depends on various histone modifications, of which phosphorylation of histone H3 at serine...
