Genetics and Molecular Biology

STRUCTURE: One difference between RNA and DNA is -

• RNA has thymine where DNA has ademine

• DNA is single stranded where RNA is double stranded

• DNA is made in the nucleus where RNA is made in the ribosomes

• RNA is single stranded where DNA is double stranded

STRUCTURE: What Nitrogenous Base does RNA contain that DNA does not?

• Thymine

• Uracil

• Adenine

• Love

STRUCTURE: Which 2 molecules form the sides of the DNA ladder?

• deoxyribose and adenine

• deoxyribose and a hydrogen bond

• sugar and the nucleus

• deoxyribose (sugar) and phosphate

STRUCTURE: In the DNA double helix, the bases (AtoT and CtoG) are held together by:

• polar bonds

• ionic bonds

• covalent bonds

• hydrogen bonds
