Answer #1

Solution.

Option 3. t-RNA

Because t-RNA or transfer RNA carry amino acids (charged t-RNA) to the translation site and attach to the ribosomes of the translation machinery. Therefore option 3 is the correct answer.

  • Option 1 is wrong because DNA do not directly attach to amino acid
  • Option 2 is wring because double stranded RNAs are not seen attached to the amino acids
  • Option 4 is wrong because rRNA are seen attached to ribosomes.
  • Option 5 is wrong because, mRNA are not directly attached to amino acids.

A codon is a series of three bases in mRNA which is equivalent to the 3 bases in DNA; this triplet code corresponds to one amino acid. Once the mRNA is attached to a ribosome, it can assemble the protein by translating from the “language” of nucleic acids to the “language” of amino acids. What is the processed called? In order to synthesize a protein molecule, amino acids need to be aligned in the proper sequence along the RNA sequence....

Genetic code backwards: You have just discovered a small neuropeptide that makes your friend have "dancing feet". Whenever they hear a certain song, they just have to dance. As fun as it is to make them dance whenever you want, you realize that this could be a serious problem and want to help. Since you do not have "dancing feet", you have a normal neuropetide.   You both go to a research clinic and have the small neuropetide sequenced. Your normal...
