the DNA that makes up the cell's chromosomes can be tightly compacted into a structure that is visible under a microscope, or it can be more loosely distributed and resemble a pile of string.

Chromosomes are tightly coiled structures in each of your cells that contain DNA ... and G to “bases,” which are part of the structure of DNA. Strings of these letters make up your complex ...

DNA molecules are large and ... the characteristics of a living organism. The diagram shows the relationship between the cell, its nucleus, the chromosomes in the nucleus, and genes.

Chances are you've seen an illustration of DNA's double-helix structure ... within a chromosome, which allows more than five feet of DNA to fit within the nucleus of a tiny cell.

In most animal, plant and fungal cells DNA is stored in the nucleus coiled up in thread-like structures called chromosomes. The nucleus of one of your skin cells contains about two metres of DNA ...

Cells also need to regulate the chromosome structure to enable its function. For example, when genetic information needs to be accessed, the DNA is locally read off. In particular, when it's time ...

When they analyzed germline cells, the team observed an increase in fluorescence, a sign that BBP exposure ramped up oxidative stress. This boost in stress led to DNA damage, compromised genomic ...

View Full Profile. Learn about our Editorial Policies. Earlier methods to synthesize HAC relied on linking shorter DNA constructs into a larger chromosome within the cell in a process called ...

The centromere of chromosomes plays a crucial role in cell division ... k motifs and DNA-binding regions can precisely target proteins that alter centromere chromatin structure to centromeres.

RIKEN biologists have engineered artificial structures that replicate one of life's most crucial processes—the precise division of packages of DNA known as chromosomes. When a cell starts ...
