O QUE SIGNIFICA RIBOSOME EM INGLÊS
Ribossomo
O ribossoma é uma máquina molecular grande e complexa, encontrada em todas as células vivas, que serve como o principal sítio de síntese protéica biológica. Os ribossomos ligam aminoácidos juntos na ordem especificada pelas moléculas de ARN mensageiro. Os ribosomas consistem em dois componentes principais - a subunidade ribossômica pequena que lê o ARN e a subunidade grande que une aminoácidos para formar uma cadeia polipeptídica. Cada subunidade é composta por uma ou mais moléculas de ARN ribossômico e uma variedade de proteínas. Os ribossomos e moléculas associadas também são conhecidos como o aparelho de tradução. A sequência de ADN que codifica para uma proteína pode ser copiada muitas vezes em cadeias de ARN mensageiro de uma sequência semelhante. Os ribossomas podem se ligar a uma cadeia de mRNA e usá-la como um modelo para determinar a seqüência correta de aminoácidos em uma proteína particular. Os aminoácidos são selecionados, coletados e transportados para o ribossomo por ARN de transferência, que entram em uma parte do ribossoma e se ligam à cadeia de ARN mensageiro. Os aminoácidos anexados são então ligados entre si por outra parte do ribossoma.
definição de ribosome no dicionário inglês
A definição de ribossoma no dicionário é uma das partículas numerosas e minuciosas no citoplasma das células, livre ou apegada ao retículo endoplasmático, que contém RNA e proteína e são o local da síntese protéica.
