Which of the following are not components of a nucleotide?

Which of the following are not components of a nucleotide?

The correct answer is C. An amino acid is not a component of nucleotide.

What is attached to the 5 and 3 ends of a nitrogenous base of DNA quizlet?

At one end of each strand there is a phosphate group attached to the carbon atom number 5 of the deoxyribose (this indicates the 5′ terminal) and at the other end of each strand is a hydroxyl group attached to the carbon atom number 3 of the deoxyribose (this indicates the 3′ terminal).

Which molecule has a sugar nitrogenous base and phosphate group quizlet?

-The building block of a nucleic acid -Consists of a five-C sugar covalently bonded to a nitrogenous base and a phosphate group. You just studied 22 terms!

Which part of nucleotides structure is responsible for the incredible variation that exist amongst all types of organisms?

What is the building block of carbohydrates? Which part of the nucleotides’ structure is responsible for the incredible variation that exists amongst all types of organisms? DNA consists of four unique nucleotides that each contain one unique nitrogenous base—adenine (A), thymine (T), cytosine (C), or guanine (G).

What are the 3 components of a nucleotide?

A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen-containing base. The bases used in DNA are adenine (A), cytosine (C), guanine (G), and thymine (T). In RNA, the base uracil (U) takes the place of thymine.

Which of the following is not a component of nucleic acids?

The correct answer is c. The fatty acid group is not a part of a nucleic acid. The nucleic acids are composed of three major…

What is attached to the 5 and 3 ends of a nitrogenous base of DNA?

At each point of juncture within a polynucleotide, the 5′ end of one nucleotide attaches to the 3′ end of the adjacent nucleotide through a connection called a phosphodiester bond (Figure 3). It is this alternating sugar-phosphate arrangement that forms the “backbone” of a DNA molecule.

Which of the following statements about 5 end of a polynucleotide strand of RNA is correct?

Which of the following statements about the 5′ end of a polynucleotide strand of RNA is correct? The 5′ end has a phosphate group attached to the number 5 carbon of ribose.

Which molecule is a nucleoside quizlet?

A nucleoside consists of a nitrogenous base covalently attached to a sugar (ribose or deoxyribose) but without the phosphate group. A nucleotide consists of a nitrogenous base, a sugar (ribose or deoxyribose) and one to three phosphate groups.

Which molecule is not a carbohydrate quizlet?

Which molecule is not a carbohydrate? A lipid is a hydrophobic polymer, not a carbohydrate.

Which of the following is not a structural subunit of a nucleotide?

Which of the following is not part of nucleotide structure? C is correct. The three components of a nucleotide are a 5-carbon sugar, a phosphate group, and a nitrogenous base. A nucleotide does not contain phospholipids; those are molecules that make up the cell membrane and nuclear envelope.

Which part of the nucleotides structure is responsible for the variation?

base
The part of a nucleotide that accounts for the genetic variation between individuals is C) the base.

How are phosphates attached to the sugar of a nucleotide?

A free nucleotide may have one, two, or three phosphate groups attached as a chain to the 5-carbon of the sugar. When nucleotides connect to form DNA or RNA, the phosphate of one nucleotide attaches via a phosphodiester bond to the 3-carbon of the sugar of the next nucleotide, forming the sugar-phosphate backbone of the nucleic acid.

What are the names of the nitrogenous bases in DNA?

Purines and pyrimidines are the two categories of nitrogenous bases. Adenine and guanine are purines. Cytosine, thymine, and uracil are pyrimidines. In DNA, the bases are adenine (A), thymine (T), guanine (G), and cytosine (C).

What happens when nucleotides connect to form DNA?

When nucleotides connect to form DNA or RNA, the phosphate of one nucleotide attaches via a phosphodiester bond to the 3-carbon of the sugar of the next nucleotide, forming the sugar-phosphate backbone of the nucleic acid . Helmenstine, Anne Marie, Ph.D.

What are the three parts of ribonucleic acid?

Both deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are made up of nucleotides which consist of three parts: Nitrogenous Base. Purines and pyrimidines are the two categories of nitrogenous bases.
