Target (of a herbicide or insecticide) T h e molecule (receptor, enzyme, etc.) within a weed plant or within a pest insect that a given herbicide or insecticide is “aimed” at (e.g., when scientists are conducting research aimed at creating that herbicide or insecticide). For example, glyphosate-containing herbicides act on the (target) crucial plant enzyme EPSP synthase. For example, insectresistant transgenic plants containing “B.t. gene(s)” act on (target) receptors inside the digestive system of specific insect species via the B.t. protoxin.

TAT is the main activator of HIV gene expression in cells; it is a protein which complexes with TAR (a 60-nucle- otide sequence found in all viral messenger ribonucleic acid) to mediate synthesis of proteins (in an infected cell) necessary for HIV to reproduce.

Technical Barriers To Trade (TBT) Agreement The agreement to GATT/WTO, via which WTO member nations agreed to base their import (restrictive) regulations and standards (e.g., mandatory packaging, package marking, testing, certification, labeling requirements, etc.) — known as TBT measures — only on scientific assessments of actual risks (i.e., for those TBT measures intended to protect human health, animal and plant health, or the environment) and to require only those TBT measures that do not create unnecessary obstacles to international
trade. See also WORLD TRADE ORGANIZATION

Telomerase An enzyme that enables the “repair” of telomeres (thereby stabilizing their length, and preventing “shortening” of the telomeres). The telomerase enzyme is only present in cancerous cells (thereby enabling the “immortality” of cancerous cells). Human telomerase contains an RNA component and a catalytic-protein component (i.e., a member of the reverse transcriptase “family” of enzymes). See also REVERSE

Telomeres DNA sequences, that do not code for proteins, which are located at the (end) tips of chromosomes. Telomeres consist of the sequence GGGGTT repeated many times. With the exception of certain types of cells (e.g., zygotes, cancerous cells, “immortal” hybridoma cells), portions of each telomere “break off “ each time the cell containing that chromosome divides. This “shortening” process serves to limit the lifetime (i.e., number of replications) of those (noncancerous, nonzygote, nonhybridoma,
etc.) cells. See also DEOXYRIBONUCLEIC ACID

Termination Codon Also known as terminator sequence. One of three triplet sequences (U-A-G, U-A-A, or U-G-A) found in DNA molecules (genes) that cause termination of protein synthesis; they are also called nonsense codons.

Thrombolytic Agents Bloodborne compounds (such as tissue plasminogen activator) that work to disintegrate (break up or lyse) blood
clots. See also FIBRIN, FIBRINOLYTIC AGENTS,
TISSUE PLASMINOGEN ACTIVATOR (tPA).
Thrombomodulin A cell surface protein found on endothelial cells that plays a key role in modulating the final step in the coagulation process. After thrombin binds to thrombomodulin, thrombin loses its ability to cleave fibrinogen to form fibrin. In addition, once thrombin binds to thrombomodulin, thrombin’s activation of protein C is increased 200-fold and this activated protein C then degrades factors Va and VIIIa which are both required for the production of thrombin from prothrombin. Hence, thrombomodulin modulates the activity of the enzyme thrombin causing a cessation of fullblown clotting activity. See also

Thymoleptics A class of drugs that primarily exerts its effect on the brain influencing “feeling” and behavior.
Thymus A gland that enables cells of the immune system of mammals to mature. In humans, it lies behind the breast bone and extends upward as far as the thyroid gland. The thymus is the place in the body where T lymphocytes are “taught” to distinguish foreign (e.g., pathogen) antigens from “self”
cell antigens, to avoid immune responses in which the body’s immune system attacks organs and other cells within the body (resulting in autoimmune diesease). Any T lymphocytes that remain “autoreactive” (i.e., would tend to attack “self” cells, such as organs in the body) are destroyed by the thymus via a cytotoxic mechanism.
An example of an autoimmune disease is |
|
|
multiple sclerosis (MS), where the body’s |
|
|
acetylcholine receptors are attacked by the |
|
|
body’s immune system. Since acetylcholine |
|
|
is crucial in the transmission of nerve |
|
|
impulses to the body’s muscles, such |
|
|
destruction of acetylcholine receptors results |
|
|
in loss of control of the body’s muscles. See |

Ti Plasmid Abbreviation for tumor-inducing |
|
|
plasmid or tumor induction plasmid. It is the |
|
|
plasmid of Agrobacterium tumefaciens bac- |
|
|
teria that naturally has part of its DNA trans- |
|
|
ferred to a plant when Agrobacterium |
|
|
tumefaciens infects that plant (e.g., via a |
|
|
wound in the plant). After it has been trans- |
|
|
ferred into the plant, that Ti plasmid DNA |
|
|
T |
||
segment (now known as T-DNA or trans- |
||
ferred DNA) inserts itself into the plant’s |
|
|
|
||
DNA, where it causes cells to grow into |
|
|
tumor-like structures known as galls. The Ti |
|
|
plasmid can be modified so that it can be |
|
|
utilized (by genetic engineers) to insert |
|
|
genes from other organisms into plants. See |
