Meiosis is essential for sexual reproduction and thereforeoccurs in all eukaryotes(including single-celled organisms) that reproduce sexually. ... Meiosis does not occur in archaea or bacteria, which reproduce via asexual processes such as mitosis or binary fission. Do unicellular organisms undergo mito...
Why do diploid organisms need to have specialized sex cells? Explain why mitosis alone does not produce daughter cells. How does synapsis occur in meiosis? How do germ cells make a single set of genes? If mitosis makes somatic cells, what does meiosis make?
Most plants continue to grow throughout their lives. Like other multicellular organisms, plants grow through a combination of cell growth and cell division. Cell growth increases cell size, while cell division (mitosis)increases the number of cells. ... Once cells differentiate, they can no longe...
Why is cell division important for both unicellular and multicellular organisms? Why are several chloroplasts in the plant cell? Describe multiple details of how mitosis in animal cells differs from mitosis in plant cells. Why do epithelial cells reproduce rapidly? What is the important role of mit...
These organisms are called saprophytes, and along with bacteria, recycle carbon, nitrogen, and mineral nutrients. At the other end of the spectrum are biotrophs (sometimes called obligate parasites) that derive all nutrients necessary for growth or reproduction only from a living host. Biotrophs,...
??? Missing X – Turner’s Syndrome SKY – Spectral Karyotypes Uses fluorescent “tags” specific to each chromosome You can also determine the type of inheritance of a disease Dominant: at least one or both chromosomes in the pair are affected Recessive: both chromosomes in the pair are ...
There exists no theoretical reason why all animal organisms in the world should be referred to a single kind of evolutionary unit or “brick of evolution”. The analysis presented above shows that nature is richer than our a priori expectations. To account for the observed facts, it is ...
Retinal image pigmentation can undergo a few changes in different ethnicities and influence the performance of others. The percentage of glaucoma cases in the REFUGE, DRIHST-GS1, and RIM-ONE datasets is higher than expected in a screening setting. ...
Lys9, 14, 18, 23, 27, and 56. Acetylation of H3 at Lys9 appears to have a dominant role in histone deposition and chromatin assembly in some organisms. Phosphorylation at Ser10, Ser28, and Thr11 of histone H3 is tightly correlated with chromosome condensation during both mitosis and ...
