This big ball of collaborating regulators would pluck the DNA strings to turn on some genes and suppress others, and therefore determine chromatin arrangement, RNA profile — and cell type. CoRCs have been defined for a handful of cell types, such as neural ...
What is the major structural difference between chromatin and chromosomes? How many chromosomes in a human cell? explain briefly. What material makes up chromosomes? In cell division, how do the chromosomes know where to go? What chromosomes do boys have?
One of the classic hallmarks of chromatin molecular biology is that nucleosomes are deposited on DNA during replication in S phase. However, dramatic new results in mammalian and Drosophila cells show that CENP-A deposition is uncoupled from the replication of centromere DNA. Furthermore, genetic ...
To compose a speculative music is first to draw associations with the medieval category of a “musica speculativa”, that esoteric part of music theory that lies beyond the practical and theoretical aspects of musical composition to address existential questions of “why?” 1 It was during this...

The evolution of plants to efficiently transport water and assimilates over long distances is a major evolutionary success that facilitated their growth and colonization of land. Vascular tissues, namely xylem and phloem, are characterized by high specia
Despite recent major advances in developing effective vaccines against toxoplasmosis, finding new protective vaccination strategies remains a challenging and elusive goal as it is critical to prevent the disease. Over the past few years, various experimental approaches have shown that developing an effectiv...
Single-cell epigenomics, such as single-nucleus ATAC-seq (to characterize chromatin accessibility) or DNA methylation-sequencing, has also been used to generate cell type atlases for different brain regions that are consistent with transcriptomic cell atlases and further reveal cell type-specific gene ...
What component of DNA is referred to by a 5' carbon? What is the primary level of DNA structure? What has nucleic acids? Which organic molecules are nucleic acids? What are the basic building blocks of DNA and RNA? What is the basic unit of DNA packaging in chromatin?
It is characterized by a rounding of the cell, a gain in cell vol- ume, mitochondrial swelling, dissolution of organelles, con- densation of chromatin around the nucleus, and irreparable damage to the plasma membrane both by external influences and by the release of intracellular lytic enzymes...
