gene silencingLittle is known of the molecular mechanisms whereby spermatogonia, mitotic germ cells of the testis, self-renew and differentiate into sperm(1,2). Here we show that Zfp145, encoding the transcriptional repressor Plzf, has a crucial role in spermatogenesis. Zfp145 expression was ...
The genetic basis of variation in gene expression lends itself to investigation by microarrays. For genetic analysis, we view the expression level of a gene as a quantitative or 'complex' trait, analogous to an individual's height or cholesterol level, and, therefore, as an inherited phenotype....

What is autosomal gene expression? How does gene flow stop? What is a gene that is always expressed? How can you identify gene flow in Arlequin? What is the end result of gene flow? How does gene flow contribute to evolution? How many types of gene flow are there?
(a) DNA (b) mRNA (c) tRNA (d) rRNA. Gene Expression: The genes present in an organism encode to produce an important biomolecule that is protein and the whole process of producing them by genes is called gene expression. Proteins are the main ingredient in al...

Hybridization studies with this cDNA showed that the ProTα mRNA is detectable in all the rat tissues studied but is most abundant in thymus and within this gland mainly synthesized by thymocytes. In the T-cell lineage, its expression is higher in proliferative immature thymocytes than in pre-...
Genetic information ___. (a) is carried from generation to generation in DNA (b) is subject to a mutation that may alter the function of specific genes (c) is subject to epigenetic alterations in gene expression that may occur as the result of env...
