In addition to carrying genetic material, chromosomes ensure that the DNA (which can extend to about 1.8 meters in length) is tightly compacted in a manner that allows it to fit inside the nucleus. Depending on the structure and the type of genetic material they contain, chromosomes can be ...
Genes and Chromosomes: Part Two – Cell Division and Genetic Diversity. Bypassing end replication defects comprises: replacing RNA primers by an RNAse H from a DNA strand during cell division, which activates the new DNA strand by electrical impulses and neurotransmitters from the growth hormones an...
Restriction enzyme analysis of DNA methylation at the re-expressed loci revealed hypomethylation of CpG clusters, that characterizes the relevant genes on the active X. The transfer of active and inactive X chromosomes from the native environment of the human fibroblast to the foreign environment of ...
in the long term. Another theory postulates that genome size is rather a result of genetic drift (themutational-hazardhypothesis)30. In this regard, in taxa with sustained small populations, slightly-deleterious duplicated genes and transposons will more readily become fixed by drift and consequently...
Using the GWAS Catalog as a basis, from 159 relevant studies, we isolate 37 genes that harbor association signals for four or more reproductive traits, more than half of which are linked to rare Mendelian disorders, including ten genes linked to reproductive-related disorders: FSHB, MCM8, DNA...
Much of the data resolution of the haploid non-recombining Y chromosome (NRY) haplogroup O in East Asia are still rudimentary and could be an explanatory factor for current debates on the settlement history of Island Southeast Asia (ISEA). Here, 81 slowl

The complex of DNA and proteins that makes up chromosomes; chromatin consists of nucleosomes formed of ~150 bp of DNA wrapped around a histone octamer, which can be further packaged into higher-order structures. Euchromatin A relatively loosely packaged form of chromatin that is enriched in ge...
