Nucleic acids are made up of nucleotides that contain a pentose sugar, a phosphate group, and a nitrogenous base. There are two types of nucleic acids; DNA and RNA. The difference between these two nucleic acids is their pentose sugar.
What is true about operant conditioning? .

Which is not true about nucleic acids?

Nucleic acids are not always the genetic material as there are other nucleic acids such as RNA that participates in the transcription and translation processes without acting as genetic material. The nucleic acids have forms like primary, secondary, tertiary and quaternary structures.

What do nucleic acids do quizlet?

What is the function of nucleic acids? To store and transmit hereditary information.

What is a nucleic acid in simple terms?

A nucleic acid is a chain of nucleotides which stores genetic information in biological systems. It creates DNA and RNA, which store the information needed by cells to create proteins.

What are the 5 things that make up nucleic acids?

All nucleic acids are made up of the same building blocks (monomers). Chemists call the monomers “nucleotides.” The five pieces are uracil, cytosine, thymine, adenine, and guanine. No matter what science class you are in, you will always hear about ATCG when looking at DNA. Uracil is only found in RNA.

What is the true shape of a DNA molecule?

The DNA molecule consists of two strands that wind around one another to form a shape known as a double helix.

Which is true about proteins?

A:True. Proteins are essential components of our cells, tissues, and organs. … Proteins also serve as building blocks for the structure of our tissues and organs. When we eat proteins, our digestion breaks them into their component amino acids.

What is the function of the nucleic acid?

The functions of nucleic acids have to do with the storage and expression of genetic information. Deoxyribonucleic acid (DNA) encodes the information the cell needs to make proteins. A related type of nucleic acid, called ribonucleic acid (RNA), comes in different molecular forms that participate in protein synthesis.

What do nucleic acids serve as?

Nucleic acids are naturally occurring chemical compounds that serve as the primary information-carrying molecules in cells. They play an especially important role in directing protein synthesis. The two main classes of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).

What is the primary responsibility of nucleic acids?

Nucleic acids are the main information-carrying molecules of the cell, and, by directing the process of protein synthesis, they determine the inherited characteristics of every living thing.

Where are nucleic acids?

Although first discovered within the nucleus of eukaryotic cells, nucleic acids are now known to be found in all life forms including within bacteria, archaea, mitochondria, chloroplasts, and viruses (There is debate as to whether viruses are living or non-living).

What is nucleic acid Slideshare?

HETEROCYCLIC BASES  Present in nucleic acids are divided into two types- PURINES and PYRIMIDINES. The two Purines present both DNA and RNA are adenine and guanine. The Pyrimidines cytosine is present in both DNA and RNA, whereas thymine is found in DNA only and Uracil is present in RNA only.

How nucleic acids are formed?

Nucleic acids are formed when nucleotides come together through phosphodiester linkages between the 5′ and 3′ carbon atoms. … They are composed of monomers, which are nucleotides made of three components: a 5-carbon sugar, a phosphate group and a nitrogenous base.

Why are nucleic acids acidic?

Explanation: More specifically, this acidity comes from the phosphate groups used in forming DNA and RNA molecules. These phosphate groups are quite similar to phosphoric acid. … That easily-lost proton is what causes nucleic acids to be so acidic.

What elements are in nucleic acids?

Nucleic acids contain the same elements as proteins: carbon, hydrogen, oxygen, nitrogen; plus phosphorous (C, H, O, N, and P).

What are nucleic acids polymers of?

A nucleic acid is a polymeric macromolecule made up of repeated units of monomeric ‘nucleotides’ composed of a nitrogenous heterocyclic base which is either a purine or a pyrimidine, a pentose (five carbon) sugar (either ribose or 2′-deoxyribose), and one to three phosphate groups.

How will you describe the structure of a DNA molecule why is it being compared to a twisted ladder?

Phosphates and sugars of adjacent nucleotides link to form a long polymer. … They showed that alternating deoxyribose and phosphate molecules form the twisted uprights of the DNA ladder. The rungs of the ladder are formed by complementary pairs of nitrogen bases — A always paired with T and G always paired with C.

Which option correctly describes what the shape of a DNA molecule resembles?

The DNA molecule is a long, coiled double helix that resembles a spiral staircase. In it, two strands, composed of sugar (deoxyribose) and phosphate molecules, are connected by pairs of four molecules called bases, which form the steps of the staircase.

What term is used to describe the shape of DNA Why?

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.

Which statement is true about the role of peptide bonds in protein structure?

Which factor is most important in determining a protein’s optimum pH? The locations of side-chain carboxyl groups. The locations of side-chain carboxyl groups. They make the protein rigid.

Which is true about protein digestion?

Protein digestion begins when you first start chewing. There are two enzymes in your saliva called amylase and lipase. They mostly break down carbohydrates and fats. Once a protein source reaches your stomach, hydrochloric acid and enzymes called proteases break it down into smaller chains of amino acids.

Which of the following is not true for protein engineering?

Which of the following is not an application of protein engineering? Explanation: Multiplication of natural proteins is not an application of protein engineering.

Where are nucleic acids quizlet?

Where are nucleic acids found? In the nucleus of cells.

How are nucleic acids linked to heredity?

Nuclei acids control the processes of heredity by which cells and organisms reproduce proteins. The key nucleic acids are DNA (deoxyribonucleic acid) and RNA (ribonucleic acid). The type, location, and sequencing of the nucleotides governs the biological activity of the nucleic acid. …

What are nucleic acids enlist the point of differences among DNA and RNA?

‘Nucleic acids’ is the term given to DNA and RNA and are essential for the existence of life. RNA is ribonucleic acid present in all living cells. It carries instructions from DNA which controls the synthesis of proteins but in some viruses RNA, instead of DNA carries the genetic information.

What are two interesting facts about nucleic acids?

Nucleic acids hold the basic building blocks for life. Deoxyribonucleic acid are found in all cells. DNA is organized into x-shaped chromosomes. In humans it is found in the nucleus of the cell.

How are nucleic acids used in plants?

Nucleic acids are large molecules that carry tons of small details: all the genetic information. Nucleic acids are found in every living thing — plants, animals, bacteria, viruses, fungi — that uses and converts energy. … People, animals, plants, and more all are connected by genetic material.

What is DNA Slideshare?

STRUCTURE  DNA is a long chain polymer of nucleotides  Consist of:  Deoxyribose=5 pentose sugar  Phosphate group  Organic bases  Adenine ,Guanine (purines)  Cytosine ,thymine (pyrimidines)  DNA is a double helix with 2 strands which gives ladder like shape with base pairs.

How are nucleic acids formed quizlet?

The nucleic acid forms when two polynucleotide chains join together, by hydrogen bonds between the nitrogenous bases, to form a double-stranded molecule. When the nucleic acid contains the sugar deoxyribose and the base thymine, the molecule is known as DNA.

Why are nucleic acids negatively charged?

Nucleic acids are negatively charged because they have a negatively charged phosphate group in the nucleotides.

Why are nucleotides strong acids?

Simply put, nucleotides are acidic. The presence of phosphate groups in nucleic acids causes them to be acidic in nature. … The phosphate group has hydrogen which exits by leaving behind a negative charge on it when needed hence it exhibits traits of being acidic.
