Allelic instability in mitosis can explain genome imprinting and other genetic phenomena in psoriasis. Zheng CJ. American Journal of Medical Genetics . 1994Zheng CJ , Thomson G , Peng YN ( 1994 ): Allelic instability in mitosis can explain “genome imprinting” and other genetic phenomena in ...
In which phase of the cell cycle does DNA replication occur? Answers to choose from are: G2, G0, S, G1 Please explain in detail how you get your answer. During what stage of the cell cycle does DNA replication occur? Why does DNA replication occur prior to mitosis?
Explain how this occur. Explain what occurs when a nondisjunction occurs in the formation of the gametes. Explain both meiosis and mitosis. Describe (in detail) the process of animal development (fertilization, cleavage, gastrulation, and organogenesis). What is the difference between a gamete, a...
Organization of the genome into transcriptionally active euchromatin and silenced heterochromatin is essential for eukaryotic cell function. Phase-separation has been implicated in heterochromatin formation, but it is unclear how phase-separated condensa
2- Knowing that the genes are independent, how can you explain such a result? 3- Make the factorial analysis verifying the above phenotypic proportions. ——— Answers: 1- Proportion Calculation: Divide by the smallest number: [AB] 36/6=6 [Ab] 12/6= 2 [aB] 18/6= 3 [ab] 6/6=...
We reveal the existence of a p53-driven hierarchy, where cancer cells with a gain-of-function (GOF) mutant p53 educate a dominant population of CAFs that establish a pro-metastatic environment for GOF and null p53 cancer cells alike. We also demonstrate that CAFs educated by null p53 cancer...
Single-cell RNA sequencing (scRNAseq) enables researchers to identify and characterize populations and subpopulations of different cell types in hearts recovering from myocardial infarction (MI) by characterizing the transcriptomes in thousands of indivi
Gene duplication is a normal evolutionary process. If there is no selective advantage in keeping the duplicated gene, it is usually reduced to a pseudogene and disappears from the genome. However, some paralogs are retained. These gene products are likel
A germ tube is described as an outgrowth that is produced by spores of spore-releasing fungi in the course of germination. The germ tube distinguishes, produces, and matures by the process of mitosis in order to produce somatic hyphae.
Multiple interactions with many different partners are responsible for the amazing functional versatility of proteins, especially those participating in cellular regulation. The structural properties that could facilitate multiple interactions are examin
