What Are The Similarities And Differences Between Dna And Rna Molecules?

Both DNA and RNA have four nitrogenous bases each—three of which they share (Cytosine, Adenine, and Guanine) and one that differs between the two (RNA has Uracil while DNA has Thymine).

What are the similarities and differences of DNA and RNA?

While both DNA and RNA have sugar molecules in their subunits, those sugars are slightly different. DNA uses deoxyribose, but RNA uses ribose, which has an extra hydroxyl group (OH−) tacked on. DNA and RNA also have nearly identical nitrogenous bases. Both have the bases adenine, cytosine, and guanine.

What are the differences between the DNA molecule and the RNA molecule?

DNA is a double-stranded molecule, while RNA is a single-stranded molecule. DNA and RNA base pairing is slightly different since DNA uses the bases adenine, thymine, cytosine, and guanine; RNA uses adenine, uracil, cytosine, and guanine. Uracil differs from thymine in that it lacks a methyl group on its ring.

What are the similarities between DNA and RNA molecules 4 points?

Similarities between DNA and RNA: Both are made up of five carbon- pentose sugar, phosphate and nitrogenous bases. Both are polynucleotide chains made up of a single nucleotide unit or monomers. Both biomolecules are synthesised by the polymerase enzyme. Practically, both DNA and RNA can be precipitated using alcohol.

What are 2 differences between DNA and RNA?

There are two differences that distinguish DNA from RNA: (a) RNA contains the sugar ribose, while DNA contains the slightly different sugar deoxyribose (a type of ribose that lacks one oxygen atom), and (b) RNA has the nucleobase uracil while DNA contains thymine.

What are the similarities and differences between DNA and RNA quizlet?

Terms in this set (16)

  • Both are polymers.
  • Both use polymerase.
  • Both have the bases adenine guanine and cytosine.
  • Have nucleotides.
  • Store information to build proteins.

Which of the following correctly describes a difference between DNA and RNA?

Which of the following correctly describes a difference between DNA and RNA? DNA occurs in the nucleus, whereas RNA only occurs outside the nucleus. DNA contains a ribose, whereas RNA contains a deoxyribose sugar. DNA contains four nucleotides, whereas RNA contains three.

Which of the following is not a difference between DNA and RNA?

The correct answer is (c) DNA contains alternating sugar-phosphate molecules whereas RNA does not contain sugars.

What is the relationship between RNA and DNA?

The two main types of nucleic acids are DNA and RNA. Both DNA and RNA are made from nucleotides, each containing a five-carbon sugar backbone, a phosphate group, and a nitrogen base. DNA provides the code for the cell’s activities, while RNA converts that code into proteins to carry out cellular functions.

Which do DNA and RNA have in common?

As nucleic acids, DNA and RNA share some similarities: Both DNA and RNA store genetic information. Both DNA and RNA consists of sugar, nitrogenous bases, and a phosphate backbone. On both molecules, guanine and cytosine pair with each other (are complementary).

Which of the following characteristics do DNA and RNA have in common?

Explanation: DNA and RNA share many characteristics. They are both composed of nucleotide monomers and are read in the 5′-to-3′ direction. They also share the same complementary base pairs, except RNA uses uracil in place of thymine; both contain adenine.

What is the difference between DNA and RNA quizlet?

Terms in this set (8) The three main differences between RNA and DNA is that (1) The sugar in RNA is ribose instead of deoxyribose, (2) RNA is generally single-stranded and not double-stranded, and (3) RNA contain uracil in place of thymine. Messenger RNA carry information from DNA to other parts of the cell.
