Recombinant DNA Technology

Science / Genetics / Recombinant DNA Technology: Procedure used to join together dna segments in a cell-free system (an environment outside a cell or organism). Under appropriate conditions, a recombinant dna molecule can enter a cell and replicate there, either autonomously or after it has become integrated into a cellular chromosome.

Dna Ligase

Science / Biology / Dna Ligase: In recombinant DNA technology, an enzyme that seals together two DNA fragments from different sources to form a recombinant DNA molecule. MORE

Junk DNA

Science / Genetics / Junk DNA: Stretches of dna that do not code for genes: most of the genome consists of so-called junk dna which may have regulatory and other functions. Also called non-coding dna. MORE

Mitochondrial DNA

Science / Genetics / Mitochondrial DNA: The genetic material found in mitochondria, the organelles that generate energy for the cell. Not inherited in the same fashion as nucleic dna. MORE

High Speed Technology (HST)

Technology / Computers / High Speed Technology (HST): Before the invention of the CCITT V.32 modem standards for 9600 BPS modems, US Robotics invented a proprietary protocol that runs even faster at 14,400 BPS. It became popular on US bulletin board syst MORE

Gene Chip Technology

Science / Genetics / Gene Chip Technology: Development of cdna microarrays from a large number of genes. Used to monitor and measure changes in gene expression for each gene represented on the chip. MORE

Advanced Technology Attachment (ATA)

Technology / Computers / Advanced Technology Attachment (ATA): This is a disk drive implementation developed by the Small Form Factor (SFF) Committee that integrates the controller on the disk drive itself. There are many versions of ATA, which include ATA: Also MORE
