(a) When and where does spermatogenesis in human male begin to take place? 1. Definition of Spermatogenesis: Spermatogenesis is the process of formation of sperm cells (gametes) in males.2. Location: This process occurs in the seminiferous tubules, which are located within the testes.3. Onset...
● Ignoring Social and Economic Factors: The singularity discourse often focuses heavily on technological advancements while neglecting the social and economic factors that could shape its trajectory. Critics argue that technological progress does not occur in a vacuum and that its impact is heavily infl...
however, work thus far suggests that it does occur (reviewed in Leivers and Simmons2014; see also Baker and Bellis1993; Kilgallon and Simmons2005; Leivers et al.2014). For example, men who viewed sexually explicit images suggesting sperm competition (i.e., two men with one woman) produced ...
Large chromosomal deletions, such as del(5q) and del(7q), that occur in t-MN do not harbour a single, recessive tumour suppressor gene but instead are part of a contiguous gene syndrome (CGS). Moreover, the genes involved in CGSs on these chromosomes act by haploinsufficiency. An aberran...
Does viropexis occur when a virus infects an eukaryotic cell? Do viruses with capsids undergo the lytic cycle? Is influenza a segmented RNA virus? How does an animal virus enter its host's body? Is the hanta virus a normal virus or a retrovirus? Do all viruses go through both the lyt...
“the potential pathways of transformation become finite”. This seems to imply that development is the reason why the potential pathways of transformation become finite, somehow as opposed to the possibility of being infinite. This statement also seems to imply that random genetic mutations have ...
Cellular senescence is a multifaceted process that arrests the proliferation of cells that are at risk of neoplastic transformation. Many stimuli elicit a senescence response. These include dysfunctional telomeres, DNA damage, the expression of certain oncogenes, perturbations to chromatin organization and...
Biology is built on the laws of physics and chemistry, even if the exact details of how are still being puzzled out today. And questions that my dad put to me, as part of his own research, often had me questioning both physics and biology. How does a cell know what organ to build ...

To answer the question, "Genes in the normal cells which when activated lead to oncogenic transformation are called," we will analyze the options provided and identify the correct term.1. Understanding the Question: The questio
