o a rna contains only three different nucleotides, while dna contains four different nucleotides.
o b dnas nucleotide sequence is single stranded, while rnas nucleotide sequence is double stranded.
o c rnas backbone is made up of phosphates, while dnas backbone is made up of nitrates
o d dna contains a nucleotide with thymine, while rna contains a nucleotide with uracil.

Explanation:

Question 24

DNA is double - stranded, has deoxyribose sugar, bases A, G, C, T and remains in the nucleus. RNA is single - stranded, has ribose sugar, bases A, G, C, U and leaves the nucleus.

Transcription is the process of synthesizing RNA from a DNA template. RNA polymerase is the enzyme that catalyzes the formation of RNA. Lactase is involved in lactose digestion. Protein polymerase is not a standard enzyme term (proteins are synthesized by ribosomes). DNA polymerase is involved in DNA replication.

Both DNA and RNA have four nucleotides. DNA is double - stranded and RNA is single - stranded. The backbone of both DNA and RNA is made of phosphates. DNA has thymine (T) and RNA has uracil (U) as one of their nitrogenous bases.

Answer:

C. DNA remains in the nucleus while RNA leaves the nucleus.
