Question
Studies of the structure of the T-cell receptor indicate it has significant homologies to the _________ of immunoglobulins (antibodies), with the _______ peptides resembling the heavy chain.1 pointarms; α and γarms; β and δstem; α and γstem; β and δ
Solution
Para responder a la pregunta, primero debemos entender los términos clave y la estructura de los receptores de células T y los inmunoglobulinas (anticuerpos).
- Los receptores de células T (TCR) tienen homologías significativas con los inmunoglobulinas.
- Los inmunoglobulinas tienen una estructura que incluye cadenas pesadas y ligeras.
- La pregunta menciona que los péptidos del TCR se asemejan a la cadena pesada de los inmunoglobulinas.
Ahora, revisemos las opciones:
- "arms; α and γ" no parece correcto porque "arms" no es el término adecuado para describir la estructura del TCR en comparación con los inmunoglobulinas.
- "arms; β and δ" tampoco parece correcto por la misma razón.
- "stem; α and γ" no es correcto porque "stem" no es el término adecuado.
- "stem; β and δ" es la opción correcta porque "stem" se refiere a la parte estructural que se asemeja a la cadena pesada de los inmunoglobulinas, y los péptidos β y δ son los que se asemejan a la cadena pesada.
Por lo tanto, la respuesta correcta es:
stem; β and δ
