What are the 7 steps of protein synthesis?

Terms in this set (12)

• DNA unzips in the nucleus.
• mRNA nucleotides transcribe the complementary DNA message.
• mRNA leaves nucleus and goes to ribosome.
• mRNA attaches to ribosome and first codon is read.
• tRNA brings in proper amino acid from cytoplasm.
• a second tRNA brings in new amino acid.

What is protein synthesis?

Protein synthesis is the process in which cells make proteins. It occurs in two stages: transcription and translation. Transcription is the transfer of genetic instructions in DNA to mRNA in the nucleus. ... After the mRNA is processed, it carries the instructions to a ribosome in the cytoplasm.

What are the 4 steps of protein synthesis?

Translation involves four steps:

• Initiation. The small subunit of the ribosome binds at the 5' end of the mRNA molecule and moves in a 3' direction until it meets a start codon (AUG). ...
• Elongation. ...
• Termination. ...
• Post-translation processing of the protein.

What are the 5 steps of protein synthesis?

The major steps are:

• (a) Activation of amino acids:
• (b) Transfer of amino acid to tRNA:
• (c) Initiation of polypeptide chain:
• (d) Chain Termination:
• (e) Protein translocation:

How can protein synthesis be increased?

Ten grams of essential amino acids or twenty-five grams of a complete protein are sufficient to maximally stimulate protein synthesis. Type, timing and amount of protein are all factors in maximizing muscle mass.

What is the correct order of protein synthesis?

The correct sequence of events in protein synthesis is transcription, then translation.

What are the 2 stages of protein synthesis?

Protein synthesis can be divided broadly into two phases - transcription and translation. During transcription, a section of DNA encoding a protein, known as a gene, is converted into a template molecule called messenger RNA (mRNA).

What is the first step of protein synthesis?

The first step of protein synthesis is called Transcription. It occurs in the nucleus. During transcription, mRNA transcribes (copies) DNA.

How do you teach protein synthesis?

Teaching Protein Synthesis Just Got Easier

1. USE INTERACTIVES. Check out this interactive website where you can go through the process of transcription and translation up on the board with your students. ...
2. USE PUZZLES. ...
3. USE VIDEOS. ...
4. TEACHING GENE EXPRESSION (The harder part) ...
5. USE ANALOGIES.

What are the 9 steps of protein synthesis?

Terms in this set (9)

• DNA unravels, exposing code.
• mRNA comes in.
• transcription (copying genetic code from DNA)
• mRNA exits nucleus, goes to ribosome.
• translation (gives message to ribosome)
• tRNA brings in specific amino acids (anticodons)
• protein synthesis begins.
• peptides.

How do you explain protein synthesis to a child?

Protein synthesis is a term that means making protein. The recipe for protein synthesis uses ingredients like mRNA, tRNA, and amino acids as well as a special piece of equipment called a ribosome.

What is the last step of protein synthesis?

The last step in protein synthesis is termination. During termination, the ribosome reads the stop codon in the mRNA.
