Which of the following is a component of DNA?

Which of the following is a component of DNA?

DNA has three types of chemical component: phosphate, a sugar called deoxyribose, and four nitrogenous bases—adenine, guanine, cytosine, and thymine. Two of the bases, adenine and guanine, have a double-ring structure characteristic of a type of chemical called a purine.

What are the components of DNA quizlet?

List the chemical components of DNA. Nucleotides, each with a deoxyribose molecule (5-carbon sugar molecule), a phosphate group, and a nitrogen-containing base. The four bases are adenine (A), thymine (T), guanine (G), and cytosine (C).

What best describes the contents of DNA?

What best describes the contents of DNA? It contains the instructions for building the proteins that control the cells in your body.

Which of the following best describes the structure of ATP?

Which of the following best describes the structure of ATP? ATP molecules are composed of ribose sugar, a nitrogen-containing adenine molecule, and two phosphate groups. ATP molecules are composed of a deoxyribose sugar, a nitrogen-containing variable group, and three phosphate groups.

What is a shape of DNA?

The double helix is a description of the molecular shape of a double-stranded DNA molecule. In 1953, Francis Crick and James Watson first described the molecular structure of DNA, which they called a “double helix,” in the journal Nature.

What are base pairs in DNA?

Listen to pronunciation. (bays payr) Molecules called nucleotides, on opposite strands of the DNA double helix, that form chemical bonds with one another. These chemical bonds act like rungs in a ladder and help hold the two strands of DNA together.

Which one of the following base pairs is found in DNA?

According to Watson-Crick base-pairing, which forms the basis for the helical configuration of double-stranded DNA, DNA contains four bases: the two purines adenine (A) and guanine (G) and the two pyrimidines cytosine (C) and thymine (T). Within the DNA molecule, A bonds only with T and C bonds only with G.

What are the specific base pairings in DNA and RNA?

DNA and RNA bases are also held together by chemical bonds and have specific base pairing rules. In DNA/RNA base pairing, adenine (A) pairs with uracil (U), and cytosine (C) pairs with guanine (G). The conversion of DNA to mRNA occurs when an RNA polymerase makes a complementary mRNA copy of a DNA “template” sequence.

What are the structural and functional differences between DNA and RNA?

So, the three main structural differences between RNA and DNA are as follows: RNA is single-stranded while DNA is double-stranded. RNA contains uracil while DNA contains thymine. RNA has the sugar ribose while DNA has the sugar deoxyribose.

What’s the main difference between DNA and RNA nucleotides Brainly?

DNA contains ribose sugar, and RNA contains deoxyribose sugar instead. DNA contains cytosine, and RNA contains guanine instead. DNA contains deoxyribose sugar, and RNA contains ribose sugar instead.
