Comparing DNA and RNA

There are many similarities between DNA and RNA. What statements support this idea? Check all that apply.

Check All That Apply

Both DNA and RNA nucleotides contain the nitrogenous bases adenine, cytosine, and guanine.

Both DNA and RNA contain monosaccharide sugars on their respective nucleotides.

Both DNA and RNA are involved in the "Central Dogma" of biology.

Both DNA and RNA are always double helices.

Both DNA and RNA contain phosphate groups on their respective nucleotides.

Both DNA and RNA can transport messages, act as enzymes and are part of ribosomes.

Explanation / Answer

answer:

Similarities between DNA and RNA : TRUE

Both DNA and RNA nucleotides contain the nitrogenous bases adenine, cystosine, and guanine

Explanation: RNA contains Uracil and DNA contains Thyamine. So both DNA and RNA nucleotides contain the nitrogenous bases adenine, cytosine, and guanine.

Both DNA and RNA contain monosaccharide sugars on their respective nucleotides : TRUE

Explanation: DNA contains Deoxyribose and RNA contains Ribose sugars both sugars are monosaccharide sugars on their respective nucleotides

Both DNA and RNA contain phosphate groups on their respective nucleotides : TRUE

Explanation: sugar-phosphate backbone forms the structural framework of nucleic acids and gives directionality of the molecule

Both DNA and RNA can transport messages, act as enzymes and are part of ribosomes ------ FALSE

Explanation: RNA acts as enzymes eg: Catalytic RNA and RNA is also part of ribosomes but DNA is not

Both DNA and RNA are always double helices --- FALSE

Explanation: Unlike Double strand DNA, RNA is a single molecule ,RNA can form complementary basepairing form intrastrand doube helixes as in t-RNA. B- DNA can exists as double helices and RNA double helices exists as hairpin loop and internal loops
