Unit 4 Molecular Genetics

Which of the following are differences in the structure between RNA and DNA

• DNA uses deoxyribose sugar, RNA uses sugar ribose

• DNA pairs Adenine with Uracil, RNA pairs Adenine with Thymine

• DNA is a double helix, RNA is a single helix

• DNA pairs Adenine with Thymine, RNA pairs Adenine with Uracil

During transcription, this type of ribonucleic acid is responsible for copying the DNA and brining it out of the nucleus.

• tRNA

• mRNA

• rRNA

• dRNA

When these bond together, they form a protein

• Amino Acids

• Peptide Bonds

• Ribose

• Nucleotides
