Help: If hemoglobin is a protein, we know that it is synthesized at ribosomes.?

Question

true or false

Answer 1

uh I'm pretty sure that's false

Answer 2

true

Answer 3

true... ribosomes makes proteins and hemoglobin is one

Answer 4

Ribosome is a complex of ribosomal ribonucleic acid (rRNA) and protein. The rRNA part is synthesized from the original message called DNA in the nucleus, particularly in a region called nucleolus. The protein parts come from another DNA message that specify the production of these proteins, translated to mRNA (messenger RNA, this is different RNA than those produced in nucleolus), then the mRNA is transported out of nucleus. It is translated into protein by eventually already assembled ribosome in cytoplasm. Then, the protein parts are transported back to nucleus and together with the rRNA produced in nucleolus, they are assembled into complete ribosome. These rRNA-protein complexes are then transported out of nucleus to cytoplasm, where they do their task, to synthesize protein.

To simplify:

DNA1 --> rRNA

(nucleolus)

DNA2 --> mRNA --> Protein

(nucleus) (cytoplasm)

Protein + rRNA --> Ribosome

(nucleolus)
