Genomics

Genes are responsible for transmitting the characters located on the chromosomes from one individual to another across the generations. Genetics is the study of different genes that are involved in different functions. Genetics is a branch of biology that studies genes, genetic diversity, and heredity in living organisms. The genetic system consists of genetic notations, which is a system of signs and symbols. Genotype refers to the organism's genetic composition, and phenotype refers to the observable property of the organism.

Question

When a cell transitions from one type to another (for example in the case of gastrulation), what must be causing this transition at a molecular level? (i.e. what is the possible mechanism for this transition)?

Expert Solution

Step 1

Cell transition is the process by which a cell of one type is getting changed to another type . During these process there are various biochemical changes that happen at molecular level .

One important biological effect of a large dose of ionizing radiation (like X-rays) is to halt cell division. How does this occur? To answer this question, state the name and role of 2 specific and important proteins involved in the process. What happens if a cell has a mutation that prevents it from halting cell division after be irradiated? Be specific and detailed. An adult human who has reached maturity will die within a few days of receiving a radiation dose large enough to stop cell division. What does that tell you about cell division? In addition, name 2 different/unique cell types that would be primarily affected.
Biologists have long been interested in the effects of radiation on cells. In one experiment, researchers examined the effect of radium on mitosis of chick embryo cells growing in culture. A population of experimental cells was examined under the microscope for the number of cells in telophase (as a measure of mitosis occurring) before, during, and after exposure to radium. The results are shown in the Figure. What is the effect of radium exposure on mitosis? Source: R. G. Canti and M. Donaldson. 1926. The effect of radium on mitosis in vitro.

A small amount if cytoplasm isolated from a mitotic cell is injected into an unfertilized frog oocyte, causing the oocyte to enter M phase. A sample of the injected cytoplasm is then taken and injected into a second oocyte, causing this cell also to enter the M phase. this process is repeated many times until essentially, none of the original protein samples remains, and yet, cytoplasm taken from the last in the series on injected oocytes is still able to trigger entry into the M phase with undiminished efficiency. Explain this remarkable observation.
