Among the many marvels of life is the cell's ability to divide and thus enable organisms to grow and renew themselves. For ...

During interphase, the cell's DNA is not condensed and is loosely distributed. A stain for heterochromatin (which indicates the position of chromosomes) shows this broad distribution of chromatin ...

Scientists at EMBL have captured how human chromosomes fold into their signature rod shape during cell division, using a ...

The nucleus of each human body cell contains 46 chromosomes. Each chromosome contains about 1000 genes. There is enough DNA in all the cells in a human body to stretch to the sun and back again ...

So, it's very easy to see,” she said. To zoom in on changes in chromosome organization during meiosis, the researchers used nuclear membrane and DNA damage protein stains to track nuclear behavior.

A 2017 study published in the journal PLOS Genetics said the chromosome's evolution of palindromes — DNA sequences that read the same forward as backward — and repetitive copies of genes could ...

Each human cell contains 23 pairs of chromosomes that carry DNA within their nucleus. The X and Y chromosomes, commonly referred to as the sex chromosomes, are one such pair. They determine the ...

Fortunately, the models yielded different predictions about the distribution of old versus new DNA ... original double-stranded DNA unwinding at a single spot on the chromosome known as the ...

Transposons, or "jumping genes"—DNA segments that can ... in bacteria with linear chromosomes, and the researchers found that bacterial transposons (versus eukaryotes) use unique mechanisms ...
