Among scientists, it is widely accepted that the structure of genomes largely controls their transcriptional activity within the cell. Structural features known as chromatin are responsible for this ...

Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from ...

Higher yields, greater resilience to climatic changes or diseases—the demands on crop plants are constantly growing. To ...

Researchers have made a surprising new discovery in the structure of the centromere, a structure that is involved in ensuring that chromosomes are segregated properly when a cell divides. Mistakes in ...

Research shows synthetic chromosomes can be transferred to human cells with potential to improve viral resistance ...
