Protein Synthesis and Coding

The main function of tRNA is to...

• carry a message that, when translated, forms proteins
• form a portion of ribosomes
• string together complementary RNA and DNA strands
• bring amino acids from the cytoplasm to the ribosomes

What occurs during protein synthesis?

• Nitrogen bases create sugar molecules.

• Amino acids link together to form proteins.

• Protein molecules create new music.

What are two types of RNA?

• protein & transfer RNA

• messenger & transfer RNA

• messenger & amino acid RNA

• messenger & protein synthesis RNA

What is a codon?

• a sequence of 3 amino acids
• a sequence of three nitrogen bases
• a sequence of 3 enzymes
• a sequence of 3 proteins

Which type of RNA delivers the genetic code to the ribosome?

• tRNA
• mRNA
• rRNA
• tmRtmRNA

What is the function of transfer RNA?

• It is a part of the ribosome.
• It bonds to other RNA molecules, leading to their destruction.
  
• It delivers the correct amino acid to the ribosome.
• It carries the information coding for the amino acid sequence of a protein.

Which of these is part of the description of protein?

• a folded chain of amino acids
• a folded chain of carbohydrates
• a branched chain of fatty acids
• a branched chain of nucleic acids

How are the amino acids linked together during translation?

• by creating peptide bonds
• by creating hydrogen bonds
• by creating covalent bonds
• by creating phospate bonds

• 1
• 3
• 6
• 8
