How do mRNA and tRNA work together to make proteins?
A. tRNA carries the instructions coded in mRNA to the ribosomes where mRNA decodes DNA to make proteins.
B. mRNA carries the instructions coded in tRNA to the ribosomes where mRNA decodes DNA to make proteins.
C. mRNA carries the instructions coded in DNA to the ribosomes where tRNA decodes the mRNA to make proteins.
D. tRNA carries the instructions coded in DNA to the ribosomes where mRNA decodes the tRNA to make proteins.
Is the answer b?
The mRNA brings the message that was transcribed by the DNA to the ribosome, while the tRNA brings the anticodon to translate the message, along with the amino acid which bonds to form a polypeptide chain. The chain is further developed into a functional protein .
Yes
So C?
1 is A, not B not D, but A
tRNA carries amino acids to the ribosome and helps form proteins.
No, the correct answer is option C. mRNA carries the instructions coded in DNA to the ribosomes where tRNA decodes the mRNA to make proteins.
To understand how mRNA and tRNA work together to make proteins, let's break it down:
1. DNA contains the genetic information that codes for proteins.
2. This genetic information is transcribed into mRNA through a process called transcription.
3. mRNA carries the instructions from DNA to the ribosomes, which are the cellular structures responsible for protein synthesis.
4. At the ribosomes, tRNA (transfer RNA) molecules interact with the mRNA.
5. Each tRNA molecule carries a specific amino acid, which is the building block of proteins.
6. The tRNA molecules have an anticodon that is complementary to the codon on the mRNA.
7. This complementary base pairing ensures that the correct amino acid is added to the growing protein chain.
8. tRNA "reads" the mRNA codons and brings the corresponding amino acids to the ribosomes.
9. The ribosomes then link the amino acids together to form a protein chain, following the instructions provided by the mRNA.
So, mRNA carries the instructions coded in DNA to the ribosomes, while tRNA decodes the mRNA to bring the correct amino acids for protein synthesis.
