Pollutants act also at DNA level producing DNA mutations and changes in epigenetic pathways inducing specific mechanisms of toxicity and/or aberrant cellular responses that may affect subsequent generation(s) through the germline. In conclusion, this review summarizes the effects caused by EDC exposure ...

What are the functions of white blood cells? How are germ cells and gametes related? Distinguish the differences between alleles, phenotype, character, and trait. During chemical signaling between cells, the receptor tyrosine kinase has multiple ways of activating other proteins, such a...

The reason is that they are not getting Pfr that will trigger them to grow like other flowering plants that are growing in the sunlight. To have a better understanding of this, you need to understand the term photoperiodism. This refers to the responses of flowering plants to lengths of dark...
are not corrected in the somatic cells, it may leads to the development of cancer or it results in the loss of function of genes. More than that, if DNA damages occur in the gametes is not rectified, it will be carried over to next generation through progenies. Thus, damage to the ...
These compounds are involved in responses to several stresses and diseases (Chen et al. 2019). Accord- ing to Schimdt et al. (2014) spermidine accumulation can strengthen apomictic plants against oxidative stresses. Genes responsible for the biosynthesis of spermidine and other polyamines were ...
Our main findings suggest that nanoparticles are generally able to reach the testicle in small quantities where they persist for several months, regardless of the route of exposure. However, there is not enough evidence that they can cross the blood–testis barrier. Of note, the majority of ...
These include aggregation in thin layers that favour the sexual encounter of gametes, interception of ciliate prey, and secretion of allelopathic substances to reach a threshold concentration [70,71]. At this point, it is important to be aware of the characteristics of the realized niche of ...
