Chromosomes DNA isn’t always rolled out, when it needs to be moved it becomes “Packaged”. A DNA wraps itself around proteins forming a neat, easy to move, package. These packages are known as chromosomes. Each species has a specific number of chromosomes (packages/volumes). Ex: Cat 38...

“总的来说,由于基因缺失和增加的两个因素,对黑猩猩和人类基因产生的后果是:黑猩猩的MSY区域内,只包含了人类MSY区域中三分之二的的‘独特的基因或基因簇’,以及一半的‘蛋白质编码转录单位’”(chimpanzee and human lineages is that the chimpanzee MSY contains only two thirds as many distinct genes or ...
Faithful DNA duplication is fundamental for all life forms. Eukaryotic genomes, organized into multiple linear chromosomes of different sizes, present a very complex and intricate framework for DNA replication regulation compared to prokaryotes. A single bidirectional replication origin is sufficient to dire...
The very long strand of DNA which further contains many genes (hundreds to thousands) makes up a chromosome. The genes are arranged in a particular sequence and have a particular location on the chromosome (called its locus). In addition to DNA, chromosomes also contain man...
What do genes and chromosomes have to do with each other? In chromosomes, stretches of DNA units called genes are arranged in a predictable order along each DNA strand. These genes contain most of the instructions found in the DNA. Where in the Cell Are Chromosomes Located? Where in a huma...

我们总结了33种预测染色质相互作用的方法,其中包括12种非监督学习方法和21种有监督学习方法(图2,表1),预测的染色质相互作用主要可分为三类:增强子-启动子相互作用(enhancer-promoter interaction,EPI)、增强子的靶标基因(enhancer-target genes,ETGs)和3D染色质相互作用(3D interaction)。 图2:染色质相互作用预测...
