Where in the cell does the second step of protein synthesis occur?
|
|
in the DNA
|
|
|
in the nucleus
|
|
|
in the Golgi Apparatus
|
|
|
at the ribosome
|
Explanation:
Detailed explanation-1: -In eukaryotic cells, transcription takes place in the nucleus . During transcription, DNA is used as a template to make a molecule of messenger RNA ( mRNA ). The molecule of mRNA then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs.
Detailed explanation-2: -Protein synthesis Synthesis of new proteins starts in the nucleus, where ribosomes get their instruction to begin the process. Sections of DNA (genes), encoding a specific protein, are copied over to messenger RNA (mRNA) strands in a process called transcription.
Detailed explanation-3: -Protein Biosynthesis Steps. Transcription. Step 1: Initiation. Step 2: Promoter escape. Step 3: Elongation.
