Question

Order the steps of Protein Synthesis(1 point) Step 1 Step 2 Step 3 Step 4

Answer 1

Protein synthesis occurs in two main stages: transcription and translation. Here’s the ordered process broken down into steps:

**Step 1**: **Transcription** - In the nucleus, DNA is transcribed to mRNA. The enzyme RNA polymerase reads the DNA sequence and synthesizes a complementary mRNA strand.

**Step 2**: **RNA Processing** - The newly formed mRNA is processed, which includes the addition of a 5' cap and a poly-A tail, as well as splicing out introns.

**Step 3**: **Translation** - The processed mRNA exits the nucleus and enters the cytoplasm, where ribosomes read the mRNA sequence and synthesize a polypeptide chain (protein) based on the sequence of codons.

**Step 4**: **Post-Translational Modifications** - After translation, the new polypeptide may undergo folding and modifications (like phosphorylation, glycosylation, etc.) to become a functional protein.

So, the correct order is:
1. Transcription
2. RNA Processing
3. Translation
4. Post-Translational Modifications
