Can beef proteins nucleic acids and polysaccharides?

Proteins, nucleic acids, and most carbohydrates (the polysaccharides) are macromolecules formed by the joining (polymerization) of hundreds or thousands of low-molecular-weight precursors: amino acids, nucleotides, and simple sugars, respectively.

Are proteins and nucleic acids polymers?

Carbohydrates, nucleic acids, and proteins are often found as long polymers in nature. Because of their polymeric nature and their large (sometimes huge!) size, they are classified as macromolecules, big (macro-) molecules made through the joining of smaller subunits.

What is the difference between polysaccharides and nucleic acids?

Cellulose, a polysaccharide ( poly meaning many, and saccharide referring to sugar), is classified as a carbohydrate. It is found in the cell wall of plants. Nucleic acids are molecules found in the nucleus and help with genetic material, like what DNA does for us.10 nov. 2015

What is used to build proteins and nucleic acids?

DNA and RNA are important macromolecules. The double-helix macromolecule DNA contains the genetic information necessary to guide construction of all the proteins in a cell and thus allow the continuity of life.

What’s an example of nucleic acids?

Two examples of nucleic acids include deoxyribonucleic acid (better known as DNA) and ribonucleic acid (better known as RNA). These molecules are composed of long strands of nucleotides held together by covalent bonds. Nucleic acids can be found within the nucleus and cytoplasm of our cells.25 jan. 2020

Are nucleic acids Heteropolymers?

DNA is HETEROPOLYMER . HETEROPOLYMER made of AMINO ACIDS. While a nucleic acid like DNA or RNA is made of only 4 types of nucleotide monomers, Upvote | 7.

What is the function of nucleic acids?

Nucleic acid is an important class of macromolecules found in all cells and viruses. 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.

What are the 4 natural polymers?

Examples of naturally occurring polymers are silk, wool, DNA, cellulose and proteins.

What are the 4 types of polymers?

Terms. Synthetic polymers are human-made polymers. From the utility point of view, they can be classified into four main categories: thermoplastics, thermosets, elastomers, and synthetic fibers.

What do polysaccharides nucleic acid and proteins have in common?

A. none of them are polymersB. they all contain nitrogenC.7 jan. 2019

How are nucleic acids and proteins similar?

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.13 août 2020

How are nucleic acids regulated?

For the synthesis of each of the different kinds of polypeptides a specific mRNA is expressed. The expression of the genetic information is mainly regulated by direct interactions of control elements located on DNA and RNA with certain protein factors.

How do proteins depend on nucleic acids?

The sequence of the codons in nucleic acids determines the sequence of amino acids in a protein. Each codon is composed of three nucleotides (nitrogen bases), and codes for a particular amino acid (or stop codon). The sequence of amino acids determines the structure of a protein, which determines its function.5 mai 2015

What is the main function of tRNA?

Transfer ribonucleic acid (tRNA) is a type of RNA molecule that helps decode a messenger RNA (mRNA) sequence into a protein. tRNAs function at specific sites in the ribosome during translation, which is a process that synthesizes a protein from an mRNA molecule.

What is the functional group of nucleic acids?

nucleic acid—–one phosphate group, one nitrogen containing base (pyrimidine or purine) and a sugar molecule, which in turn has alcohol and aldehyde/ketone group.3 sept. 2015
