Any DNA between these two gene segments is deleted.

All other gene segments between V and D segments are now deleted from the cell's genome.

If the sequences of gene segments were published, the Government would be unable to go back and file to patent them.

A flu particle is a sphere about a millionth of an inch in diameter, containing just eight disconnected gene segments.

So, the scientists reasoned, why not use Agrobacterium to insert their own synthetic gene segments into the potato cell?

One copy of each gene segment is packaged per virion.

In most cases each gene segment encodes a single open reading frame (ORF).

The millions of copies of the gene segment are labelled with a radioactive probe as they are being made.

T cells have receptors which are generated by randomly shuffling gene segments.

Many proteins are the result of the shuffling of gene segments.
