What is true about operant conditioning? .
How will you describe the structure of a DNA molecule why is it being compared to a twisted ladder?
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 is the function of nucleic acids? To store and transmit hereditary information.
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.
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.
The DNA molecule consists of two strands that wind around one another to form a shape known as a double helix.
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.
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.
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).
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.
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).
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.
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.
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.
Nucleic acids contain the same elements as proteins: carbon, hydrogen, oxygen, nitrogen; plus phosphorous (C, H, O, N, and P).
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.
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.
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.
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 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.
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 an application of protein engineering? Explanation: Multiplication of natural proteins is not an application of protein engineering.
Where are nucleic acids found? In the nucleus of cells.
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. …
‘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.
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.
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.
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.
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.
Nucleic acids are negatively charged because they have a negatively charged phosphate group in the nucleotides.
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.
