Answer: Nucleic acids, which include DNA (deoxyribonucleic acid) and RNA (ribonucleic acid), are made from monomers known as nucleotides. Each nucleotide has three components: a 5-carbon sugar, a phosphate group, and a nitrogenous base. If the sugar is deoxyribose, the polymer is DNA.

What are examples of nucleic acids?

The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA is the genetic material found in all living organisms, ranging from single-celled bacteria to multicellular mammals. The other type of nucleic acid, RNA, is mostly involved in protein synthesis.

Which substance is a nucleic acid quizlet?

ribonucleic acid, a nucleic acid present in all living cells.

Is RNA a nucleic acid?

RNA, or ribonucleic acid, is a nucleic acid that is similar in structure to DNA but different in subtle ways. The cell uses RNA for a number of different tasks, one of which is called messenger RNA, or mRNA.

Do we eat nucleic acids?

The nucleic acids, DNA and RNA, are required for the storage and expression of genetic information. ... Because they are formed in the body, nucleic acids are not essential nutrients. Dietary sources are plant and animal foods like meat, certain vegetables and alcohol.

What are 4 types of nucleic acids?

Basic structure

Each nucleic acid contains four of five possible nitrogen-containing bases: adenine (A), guanine (G), cytosine (C), thymine (T), and uracil (U). A and G are categorized as purines, and C, T, and U are collectively called pyrimidines.

Which best describes the components of nucleic acids?

The statement which describes best about nucleic acids is: They are made up of 'nitrogen bases', 'sugars' and 'phosphates'. EXPLANATION: Nucleic acids are biomolecules that are known to all forms of life. Nucleic acids are an overall name for 'DNA' and 'RNA'.

How are proteins and nucleic acids related?

Protein is a molecule made up of polypeptides. It is a class of biological molecule consisting of chains of amino acids called polypeptides. Nucleic acid is a class of macromolecules made up of long chain of polynucleotide that includes deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).

How are proteins and nucleic acids related quizlet?

what is the relationship between DNA and proteins? a DNA molecule that contains the information to code for one specific protein. The sequence of bases in the DNA molecule determines the sequence of amino acids in a protein. ... Each polypeptide has a unique sequence of amino acids.

What are 3 nucleic acids examples?

Examples of Nucleic Acids
  • deoxyribonucleic acid (DNA)
  • ribonucleic acid (RNA)
  • messenger RNA (mRNA)
  • transfer RNA (tRNA)
  • ribosomal RNA (rRNA)

What are nucleic acids simple definition?

"Nucleic acid" is the term we use to describe specific large molecules in the cell. So they're actually made of polymers of strings of repeating units, and the two most famous of the nucleic acids, that you've heard about, are DNA and RNA. And nucleic acids in the cell act to actually store information.

What are 3 types of nucleic acids?

  • Deoxyribonucleic acid.
  • Ribonucleic acid.
  • Artificial nucleic acid.

How are nucleic acids and proteins similar answers?

Nucleic acids contain the same elements as proteins: carbon, hydrogen, oxygen, nitrogen; plus phosphorous (C, H, O, N, and P). Nucleic acids are very large macromolecules composed of repetitive units of the same building blocks, nucleotides, similar to a pearl necklace made of many pearls.

What is a building block of proteins and nucleic acid?

Key terms. A large, organic molecule such as carbohydrates, lipids, proteins, and nucleic acids. A molecule that is a building block for larger molecules (polymers). For example, an amino acid acts as the building blocks for proteins.

Do proteins and nucleic acids both provide energy?

Unlike the other three macromolecules (carbohydrates, lipids, and proteins), nucleic acids are not used for energy production; therefore, the results stated in this question don't seem valid. Both DNA and RNA are made up of nucleic acids.

What foods have nucleic acids?

Not only did cultivated plants such as cereals and pulses show a high RNA-equivalent content but also vegetables such as spinach, leek, broccoli, Chinese cabbage and cauliflower.

How are nucleic acids used in medicine?

Nucleic acid therapeutics, based on nucleic acids or closely related chemical compounds, are an emerging new class of therapeutics for treating unmet medical needs. They are capable of targeting a disease at the genetic level by preventing the expression of disease-causing proteins.

Which type of polymer is RNA?

Ribonucleic acid or RNA is a nucleic acid polymer consisting of nucleotide monomers that plays several important roles in the processes that translate genetic information from deoxyribonucleic acid (DNA) into protein products; RNA acts as a messenger between DNA and the protein synthesis complexes known as ribosomes, ...

What statement correctly compares nucleic acids and carbohydrates?

Answer: The correct answer is 4) They both contain carbon, but only nucleic acids contain phosphorous. Nucleic acid and carbohydrates are essential biomolecules, which are important for the survival of life forms. DNA and RNA comprises the nucleic acid, which posses the genetic information of the living organism.

What is one of the primary functions of this food in the body?

What is one of the primary functions of this food in the body? carbohydrate. Glycogen is an energy-storage molecule in humans.

How do we get nucleic acids?

Nucleic acids come in two natural forms called deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). Nucleic acids are made of biopolymers, which are naturally-occurring, repeated sets of monomers (making polymers) that then create nucleotides, which form nucleic acids.

How does a human body produce nucleic acid?

Your cells contain DNA in their nuclei, and the DNA encodes genetic information that your cells use to make the structural and functional proteins that allow them to operate. When you produce new cells, old cells duplicate their genetic information, producing two identical sets of DNA.

What is the simplest nucleic acid?

The simplest of the polynucleotides is a single chain in which the pentose sugar is always ribose. The name of this polynucleotide comes from the sugar ribonucleic acid, abbreviated to the three letters RNA. Adenine, guanine, cytosine and uracil are the four nitrogenous bases always found in RNA.

How do nucleic acids create proteins?

In the process of transcription, the information stored in DNA is copied into ribonucleic acid (RNA), which has three distinct roles in protein synthesis. ... As the correct amino acids are brought into sequence by tRNAs, they are linked by peptide bonds to make proteins.
