Prospective parents using in vitro fertilization (IVF) will soon be able to select embryos based on their potential risk for ...

As direct descendants of ancient bacteria, mitochondria have always been a little alien. Now a study shows that mitochondria are possibly even stranger than we thought. Mitochondria in our brain ...

To fit into the tiny nucleus, DNA gets compacted by being coiled as if on a spool and further compressed into the well-known shape of chromosomes, which we all encountered in a biology textbook.

DNA is organized in segments on chromosomes called genes ... At the center of each cell lies a nucleus, which contains the information the cell needs to do its job. That information exists ...

These findings help us better understand the structure and function of our chromosomes ... cell in your body faces when packing its DNA into its tiny nucleus. To achieve this, nature employs ...

Chromosomes are thread-like structures comprising DNA that are present inside the nucleus of every cell in the body. Specific segments of DNA are called genes. Every chromosome contains many genes ...

so that each new cell’s nucleus gets one chromosome from each pair. The unattached DNA fragments remain in the center of the dividing cell, where they will be randomly pushed into one of the two new ...

One hypothesis is that the DNA loops could determine which genes are switched on in the cell. Inside a nucleus, chromosomes jumble together like a game of Twister. This can bring regulatory elements, ...

Sex chromosomes are chromosomes, or packages of DNA, that are found inside the nucleus of all of your cells. There are two different kinds: X and Y, which determine whether you’re biologically ...

The DNA coils into structures called chromosomes. The chromosomes are found in the nucleus of each cell. Figure caption, Each cell with a nucleus contains chromosomes, which are made from DNA ...

However, unlike the nucleus, the nucleoid constantly undergoes structural changes. The chromosomes within the prokaryotes are also found in the form of small molecules of DNA called plasmids.
