Question

what is different between dna and rna? 1 point rna is longer than dna dna is single stranded dna uses uracil instead of thymine rna uses uracil instead of thymine which type of rna contains the genetic code (sequence of codons) that 1 point dictates the order of amino acids to be linked in a protein? transfer rna (trna) messenger rna (mrna) ribosomal rna (rrna) small nuclear rna (snrna)

Explanation:

For the first question:

• DNA is double - stranded and longer in most cases. RNA is usually single - stranded. DNA uses Thymine (\(T\)) as a nitrogenous base, while RNA uses Uracil (\(U\)) instead of Thymine.

For the second question:

• mRNA (messenger RNA) carries the genetic code (sequence of codons) from DNA in the nucleus to the ribosome in the cytoplasm, which dictates the order of amino acids in a protein. tRNA (transfer RNA) brings amino acids to the ribosome. rRNA (ribosomal RNA) is a component of the ribosome. snRNA (small nuclear RNA) is involved in RNA splicing.

Answer:

1. RNA uses Uracil instead of Thymine.
2. Messenger RNA (mRNA).
