Question

question 10.
study the sentences describing the steps of protein synthesis. which sequence places the steps in the correct order?

1. transfer rna picks up individual amino acids and carries them to the ribosome.
2. ribosomal rna bonds mrna and trna.
3. a single strand of dna serves as a template for making mrna.
4. messenger rna carries the sequence of nucleotides to the ribosomes.
5. a protein is synthesized.

a. 2,5,3,4,1
b. 3,4,1,2,5
c. 3,2,4,5,1

Explanation:

Protein synthesis starts with transcription: DNA acts as a template to make mRNA (step 3). mRNA then carries the nucleotide sequence to ribosomes (step 4). Next, ribosomal RNA binds mRNA and tRNA (step 2). tRNA delivers amino acids to the ribosome (step 1). Finally, the amino acids are assembled into a protein (step 5).

Answer:

C. 3,2,4,5,1
