Bioninja Translation

What is the role of the small ribosomal subunit during translation?

• Binds to mRNA and moves along in a 5’ → 3’ direction

• Binds to the initiator tRNA via the P site

• Transfers amino acids to the new tRNA molecule

• Releases the deacylated tRNA

Explain the process of protein synthesis at the ribosome.

Which type of protein structure is formed by interactions between variable groups such as hydrogen bonds, ionic bonds, and disulphide bonds?

• Primary structure

• Secondary structure

• Tertiary structure

• Quaternary structure

Describe the difference between fibrous and globular proteins in terms of their structure and function.

What happens to a protein targeted for secretion in eukaryotic cells?

• It remains in the cytosol

• It is bound to the endoplasmic reticulum

• It is immediately released by the Golgi body

• It is tagged with ubiquitin

Discuss the role of proteasomes in maintaining a functional proteome.

How does the primary structure of a protein affect its overall conformation?

• It determines the sequence of amino acids

• It forms the a-helix or b-pleated sheet

• It influences the folding into a complex 3D shape

• It interacts with multiple polypeptides
