Question

3. (3pts) Using numbers 1-7, label the steps for Transcription, Translation and release of an extracellular protein. Leave blank the steps that are not used. translocation of mRNA through a nucleopore protein containing vesicle fuses with the plasma membrane mRNA translation occurs on a free cytosolic ribosome RNA polymerase at work in the nucleus protein containing vesicle buds off of the lysosome DNA polymerase at work in the nucleus mRNA translation occurs on a rough endoplasmic reticulum bound ribosome protein modification occurs in the Golgi apparatus mRNA translation occurs on a mitochondrial ribosome protein containing vesicle buds off of the rough endoplasmic reticulum protein containing vesicle buds off of the golgi apparatus

Explanation / Answer

For synthesis and release of extracellular protein following steps are taken

1.RNA polymerase works in nucleus to produce single stranged mRNA.

2.Then mRNA after processing into nucleus and passes through nuclear pore into the cytoplasm for translation.

3. mRNA translation occur at ribosome bound yo RER.

4. Protein containing vesicle buds off from the RER.

5. And budded vesicle is received by near by golgi for sorting and processing and after processing it is released as vesicle into cytoplasm.

6. Into cytoplasm protein containing vesicle travel and fuses with the plasma membrane to release extracellularly by exocytosis.
