The recombination-activating genes (RAGs) encode enzymes that play an important role in the rearrangement and recombination of the genes of immunoglobulin and T cell receptor molecules, however there is no evidence to suggest the developing T cells can undergo receptor editing in the same way that B cells do. There are two recombination-activating gene products known as RAG-1 and RAG-2, whose cellular expression is restricted to lymphocytes during their developmental stages. RAG-1 and RAG-2 are essential to the generation of mature B and T lymphocytes, two cell types that are crucial components of the adaptive immune system.

do t cells express rag-1 and rag-2?

A: yes

Soup preparation may use chicken or pork broth, or may be meat-free. Common key ingredients in the American Chinese version include bamboo shoots, toasted sesame oil, wood ear, cloud ear fungus, day lily buds, vinegar, egg, corn starch, and white pepper. Other ingredients include button mushrooms and small slices of tofu skin. It is comparatively thicker than the Chinese cuisine versions due to the addition of cornstarch. This soup is usually considered a healthy option at most Chinese establishments and, other than being high in sodium, is a very healthy soup overall.

does hot and sour soup have a lot of sodium?

A: yes

The Ford Escape is a compact crossover vehicle sold by Ford since 2000 over three generations. Ford released the original model in 2000 for the 2001 model year--a model jointly developed and released with Mazda of Japan--who took a lead in the engineering of the two models and sold their version as the Mazda Tribute. Although the Escape and Tribute share the same underpinnings constructed from the Ford CD2 platform (based on Mazda GF underpinnings), the only panels common to the two vehicles are the roof and floor pressings. Powertrains were supplied by Mazda with respect to the base inline-four engine, with Ford providing the optional V6. At first, the twinned models were assembled by Ford in the US for North American consumption, with Mazda in Japan supplying cars for other markets. This followed a long history of Mazda-derived Fords, starting with the Ford Courier in the 1970s. Ford also sold the first generation Escape in Europe and China as the Ford Maverick, replacing the previous Nissan-sourced model. Then in 2004, for the 2005 model year, Ford's luxury Mercury division released a rebadged version called the Mercury Mariner, sold mainly in North America. The first iteration Escape remains notable as the first SUV to offer a hybrid drivetrain option, released in 2004 for the 2005 model year to North American markets only.

does the ford escape come in a hybrid?

A: yes

The most common use is in motor vehicles, where the transmission adapts the output of the internal combustion engine to the drive wheels. Such engines need to operate at a relatively high rotational speed, which is inappropriate for starting, stopping, and slower travel. The transmission reduces the higher engine speed to the slower wheel speed, increasing torque in the process. Transmissions are also used on pedal bicycles, fixed machines, and where different rotational speeds and torques are adapted.

is a transmission and engine the same thing?

A:
no
