Question

transcription and translation
how is rna similar to dna?
they both contain ribose sugar.
they both contain uracil.
they are both single strands of nucleotides.
they both contain nucleotides.

Explanation:

• DNA has deoxyribose sugar, RNA has ribose sugar. So "They both contain ribose sugar" is wrong.
• DNA has thymine, RNA has uracil. So "They both contain uracil" is wrong.
• DNA is double - stranded (in most cases), RNA is single - stranded. So "They are both single strands of nucleotides" is wrong.
• Both DNA and RNA are nucleic acids. Nucleic acids are made up of nucleotides. So "They both contain nucleotides" is correct.

Answer:

They both contain nucleotides.
