Zorluk: OrtaCell Structure and Function

During a laboratory investigation, a researcher introduces a compound that selectively prevents messenger RNA (mRNA) from being translated into polypeptide chains. Which cellular organelle is directly targeted and inhibited by this compound?

  1. A
    Mitochondria
  2. B
    Chloroplasts
  3. RibosomesCevap
  4. D
    Cell wall

Cevap

Ribosomes are the cellular organelles directly responsible for translating messenger RNA (mRNA) into polypeptide chains during protein synthesis.
Ribosomes are the cellular complexes responsible for protein synthesis. They bind to messenger RNA (mRNA) strands and assemble amino acids into polypeptide chains according to the genetic code. Inhibiting mRNA translation directly impairs ribosomal function.

Adım Adım Çözüm

1
Identify the cellular process disrupted in the scenario.
The compound specifically halts the translation of mRNA into polypeptide chains (proteins).
Determining the exact metabolic pathway affected pinpoints which organelle is malfunctioning.
2
Match the biological process of translation to its corresponding organelle.
Ribosomes read mRNA codons and bind matching transfer RNA (tRNA) molecules to link amino acids together.
Ribosomes serve as the enzymatic machinery for protein synthesis in all living cells.
