Question

what is the first step in protein synthesis? (1 point)
a ribosome attaches to the mrna.
dna unzips between the base pairs.
amino acids are linked together to form strands of proteins.
information is delivered from dna to the ribosome.
check answer remaining attempts :

Explanation:

To determine the first step in protein synthesis, we analyze each option:

• A ribosome attaching to mRNA occurs later in translation.
• DNA unzipping between base pairs is the first step of transcription (part of protein synthesis), as it allows RNA polymerase to access the DNA to make mRNA.
• Amino acids linking to form proteins is the final step of translation.
• Delivering information from DNA to ribosome involves transcription and mRNA transport, which happens after DNA unzipping.

Answer:

B. DNA unzips between the base pairs.
