What are the 5 main elements of nucleic acids?
The five elements necessary to construct a nucleic acid chain are carbon, hydrogen, oxygen, nitrogen, and phosphorus.
What 3 things are nucleotides made of?
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).
What are nucleic acids made of quizlet?
Nucleic acids are made up of carbon, hydrogen, oxygen and phosphate. DNA is a double-stranded polynucleotide, which means it is made up of many nucleotide molecules joined to each other with covalent bonds, which form by condensation reactions.
What is the main function of nucleic 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.
Do nucleic acids have oxygen?
Nucleic acids include RNA (ribonucleic acid) as well as DNA (deoxyribonucleic acid). Both types of nucleic acids contain the elements carbon, hydrogen, oxygen, nitrogen, and phosphorus.
What does the D in DNA stand for?
= En Español. DNA is the chemical name for the molecule that carries genetic instructions in all living things.
What are the two main types 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. The two main classes of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
Where do nucleotides come from?
Free nucleotides must be available in a cell’s nucleus to produce mRNA strands. Where do these free nucleotides come from? The free nucleotides come from the cytoplasm where older mRNA has been hydrolyzed by exonucleases.
What are the functions of nucleic acids quizlet?
What is the function of nucleic acids? To store and transmit hereditary information.
What is the bond in nucleic acids?
DNA and RNA are composed of nucleotides that are linked to one another in a chain by chemical bonds, called ester bonds, between the sugar base of one nucleotide and the phosphate group of the adjacent nucleotide. The sugar is the 3′ end, and the phosphate is the 5′ end of each nucleiotide.
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 foods contain 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.
What is the structure and function of nucleic acids?
Nucleic acids, deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), carry genetic information which is read in cells to make the RNA and proteins by which living things function. The well-known structure of the DNA double helix allows this information to be copied and passed on to the next generation.
What are two important functions of nucleic acids?
Two main functions of nucleic acids are: (i) DNA is responsible for the transmission of inherent characters from one generation to the next. This process of transmission is called heredity. (ii) Nucleic acids (both DNA and RNA) are responsible for protein synthesis in a cell.
