Eukaryotes accomplish this feat by wrapping their DNA around special proteins called histones, thereby compacting it enough to fit inside the nucleus (Figure 8). Together, eukaryotic DNA and the ...

The secret to cellular youth may depend on keeping the nucleolus—a condensed structure inside the nucleus of a cell—small, ...

The central dogma of biology defines the flow of genetic information: It describes how proteins are made from mRNA templates, ...

New research sheds light on how cells repair damaged DNA. For the first time, the team has mapped the activity of repair proteins in individual human cells. The study demonstrates how these proteins ...

DNA comprises the genes and chromosomes that govern the development of an individual organism. Coiled inside the nucleus of the cell, DNA stores all the information needed in reproducing that ...

With the exception of red blood cells, which contain no nucleus and no nuclear DNA, every one of these cells contains the human genome -- a string of three billion A's, C's, G's, and T's.

some sequences are only intended to make proteins that stay inside the nucleus and monitor the DNA itself. These sequences often serve as binding sites for special regulatory proteins that manage ...

The nucleus inside a cell is an important organelle involved in almost all biological phenomena, such as DNA replication and transcription. However, little progress has been made in studying the ...

Remember that cells always contain DNA? Well, in eukaryotic cells, the genetic material is kept inside a nucleus. Think of it like a little folder. And they have Mitochondria. This is where cells ...
