It's 4. just took it, that's 1000% the right answer. that other person stinks for that non-answer, sorry. hope this helps.
ps. if it's not obvious, you figure it out by taking the hypotenuse (120) and putting it over the height (30). 120/30 is pretty simple division.
Sorry the photo isn't clear
Answer:
(A). mRNA.
Explanation:
During protein synthesis, information present in DNA as triplet codons gets transferred to mRNA molecule, by the process of transcription. The mRNA than gets transported to the cytosol, where it associates with ribosomes.
Ribosomes are known as protein factories of the cells as they provide platform for translation. During translation, information present in mRNA is used to translate polypeptide chain or protein as each codon codes for a specific amino acid.
Thus, the correct answer is option (A).
