Question

rna has how many nitrogenous bases? *
1
2
3
4
5
which nitrogenous base does dna have that rna does not have *
adenine
thymine
uracil
guanine
which is not a difference between dna and rna *
rna has uracil and dna has thymine
rna is single stranded while dna is double stranded
dna is missing an oxygen
rna has nothing to do with our genetic information

Explanation:

• First question: RNA has four nitrogenous bases: adenine (A), guanine (G), cytosine (C), and uracil (U).
• Second question: DNA has thymine (T) while RNA has uracil (U). Adenine, guanine, and cytosine are common to both.
• Third question: RNA is involved in processes related to genetic information (e.g., mRNA carries genetic code from DNA to ribosomes for protein synthesis).

Answer:

• First question: 4
• Second question: Thymine
• Third question: RNA has nothing to do with our genetic information
