1. Explain the transcription and translation mechanism of
protein and the role of GTP in translation process
I want to know the answer of this question less than one
page
Which of the following aspect of translation applies to eukaryotes
but not prokaryotes? a.)Transcription and translation without
exception occur in the same cellular space and at the same time.
b.)Their ribosomal subunits contain one less rRNA, fewer
polypeptides, and have lower molecular weights. c.)A pre-mRNA is
processed at each end and spliced to become a mature mRNA
transcript. d.)tRNAs and rRNAs undergo processing to achieve their
mature, functional form. e.)A single mRNA transcript may contain
several coding regions that encode...

Bacterial cells couple the process of transcription and
translation. In eukaryotic cells, the process of transcription and
translation are uncoupled or occur separately. Provide explanations
as to why bacterial cells can couple the process of transcription
and translation while in eukaryotic cells, the process is
separated.
“Coupled transcription-translation” means _,
and the coupling contributes to gene expression regulation via
___.
A
transcription can start before the end of translation, lacI
repression
B
translation can start before the end of transcription,
attenuation
C
translation can start before the end of transcription, CRP
activation
D
transcription can start before the end of translation, LacI
repression
E
translation can start only after transcription is achieved,
attenuation
Which of the following elements can terminate transcription in
prokaryotes? It is ___...
