Question

trna stands for transfer rna, and its function is to... (4:10)
a. take instructions from the nucleus into the cytoplasm
b. transfer the correct amino acids to the ribosome to make a protein
c. assemble a protein
question 8
what is the building block for proteins? (4:12 - 4:25)
monosaccharide
amino acid
nucleotide

Explanation:

• For the first question: tRNA (transfer RNA) has the function of transferring the correct amino acids to the ribosome during protein synthesis. mRNA (messenger RNA) takes instructions from the nucleus into the cytoplasm, and ribosomes (along with rRNA - ribosomal RNA) are involved in assembling proteins.
• For the second question: Proteins are made up of amino acids. Monosaccharides are the building blocks of carbohydrates, and nucleotides are the building blocks of nucleic acids (like DNA and RNA).

Answer:

• First question: B. transfer the correct amino acids to the ribosome to make a protein
• Second question: amino acid
