Question

identify each statement as being true for dna, rna, or both.
single strand
double strand
shaped as a double helix
has nitrogen base adenine (a)
has nitrogen base cytosine (c)
has nitrogen base guanine (g)
has nitrogen base thymine (t)
has nitrogen base uracil (u)
made up of nucleotides
contains a phosphate group

Explanation:

• Single Strand: RNA is typically single - stranded. DNA is usually double - stranded, so this is true for RNA.
• Double Strand: DNA is double - stranded. RNA is usually single - stranded, so this is true for DNA.
• Shaped as a double helix: DNA has a double - helix structure. RNA does not, so this is true for DNA.
• Has nitrogen base Adenine (A): Both DNA and RNA have adenine as one of their nitrogenous bases.
• Has nitrogen base Cytosine (C): Both DNA and RNA have cytosine as one of their nitrogenous bases.
• Has nitrogen base Guanine (G): Both DNA and RNA have guanine as one of their nitrogenous bases.
• Has nitrogen base Thymine (T): Thymine is specific to DNA. RNA has uracil instead.
• Has nitrogen base Uracil (U): Uracil is specific to RNA. DNA has thymine instead.
• Made up of nucleotides: Both DNA and RNA are made up of nucleotides (a sugar, a phosphate group, and a nitrogenous base).
• Contains a phosphate group: Both DNA and RNA have a phosphate group as part of their nucleotide structure.

Answer:

• Single Strand: RNA
• Double Strand: DNA
• Shaped as a double helix: DNA
• Has nitrogen base Adenine (A): Both
• Has nitrogen base Cytosine (C): Both
• Has nitrogen base Guanine (G): Both
• Has nitrogen base Thymine (T): DNA
• Has nitrogen base Uracil (U): RNA
• Made up of nucleotides: Both
• Contains a phosphate group: Both
