So, nuclear genes come in allelic pairs that are often subtly different from each other. Gametes that result from meiosis are haploid and carry only a single allele (in this example, alleles A ...

Some genes are passed on from parent to offspring without ever being part of a nuclear chromosome. Where are these genes found, and how does this non-nuclear inheritance occur? But why is leaf ...

A team of stem cell scientists successfully spawned mice from two male parents that reached adulthood, a significant step, ...

A team of researchers at Åbo Akademi University in Finland made a surprising discovery. They found that Talin-1, a protein ...

Learn about our Editorial Policies. For 1.5 billion years, the mitochondrial and nuclear genomes have been coevolving. Over this time, the mitochondrial genome became reduced, retaining only 37 genes ...

Activity-dependent gene expression triggered by Ca2+ entry into neurons is ... CaMKII locally encodes L-type channel activity to signal to nuclear CREB in excitation-transcription coupling. Journal of ...

Nuclear speckles are believed to intermingle with DNA and play a role in regulating gene activity. Normal-style (left) and abberant (right) speckle patterns in cellular nuclei. Nuclear speckles ...

Discovered over 100 years ago, nuclear speckles are tiny cellular structures that reside in the nucleus. Here, they're thought to intermingle with DNA and help regulate gene activity. Alexander's ...

The nuclear orphan receptor NR2F6 has been shown to suppress the expression of proinflammatory cytokines in T lymphocytes. NR2F6 gene expression is reduced in patients with IBS or UC, but its ...
