Cells in culture will absorb amino acids form the surround culture medium. if radioactively labelled glycine,
an amino acid, is provided in the culture medium, in which organelle will radioactivity be found first
a. ribosomes
b. nucleus
lysosomes
d. golgi apparatus

To study the effects of radioactivity in the cell on amino acids, one should know the different functions of ribosomes in the cells.

The cells have different organelles carrying out different functions, such as digestion, protection, protein synthesis, and DNA replication.

Thus, the radioactive amino acids will be taken up into the cell and will be bounded by tRNAs. The tRNAs will deliver the amino acid to ribosomes, where they will be assembled and result in the polypeptide chain.

Therefore, the correct answer is Option A.

A

Explanation:

Radioactively labelled amino acids will be found in the ribosomes. These are the organelles that are the site of protein synthesis.

Amino acids are taken up into the cytoplasm from the surrounding cell culture medium. Amino acids are then bound to tRNAs (with the enzyme aminoacyl-tRNA synthetases) and taken to the ribosome, where they are assembled into a polypeptide chain by the translation machinery.

im back lol i heard you where asking for me

i wish i could with all of them i can barley see the first one so here's the answer to the first one b
