DNA - RNA

Question 1

RNA

Answer 1

• ribonucleic acid
• ribose sugar instead of deoxyribose
• single-stranded
• uracil replaces thymine

Question 2

messenger RNA (mRNA)

Answer 2

• carries copies of instructions to make proteins from the DNA to the rest of the cell
• this molecule is small enough to leave the nucleus unlike DNA

Question 3

ribosomal RNA (rRNA)

Answer 3

• makes up a major part of the ribosome

- involved in protein synthesis

Question 4

transfer RNA (tRNA)

Answer 4

• transfers each amino acid (aa) to the ribosome during protein synthesis
• each tRNA molecule has an anticodon on it that codes for a specific amino acid
