DNA or deoxyribonucleic acid is composed of phosphates, a pentose sugar (in DNA deoxyribose), and one of four nitrogen containing bases (A,T,C, or G). Deoxyribose contains a singe Hydrogen atom where Ribose (the RNA sugar equivalent) contains a hydroxyl group (-OH). RNA also does not contain the DNA base, Thymine, and contains Uracil in it's place to bind to Adenine in Thymine's place. There are many types of RNA and each of them has additional differences as well, but these are the basics of the chemical differences.
What else can I help you with?
What is ribosomes function?
RibosomesProduces proteins.
What are the Examples of intra cellular enzymes?
RNA/DNA polymerases - Reverse Transcriptase. Helicase. Binding proteins. Enzymes simply act on a substrate - there are tonnes.
How does DNA function in a living cell?
DNA serves as the genetic blueprint of a cell, containing the instructions for building and maintaining an organism. It is transcribed into RNA, which is then translated into proteins, the workhorses of the cell. DNA replication ensures proper cell division and inheritance of genetic material.
Are bio-catalysts always proteins?
There are a few RNA catalysts are known, but the majority is only proteins. Biochemical reactions are speed by enzymes by lowering the activation energy. Enzymes like other proteins are coded in DNA.
What is the source of enzymes?
Enzymes are produced within the cell by ribosomes.
Which statement best illustrates the function of RNA in relation to DNA and proteins?
Proteins make RNA, which then creates DNA.
Are many enzymes proteins?
Yes most of the enzymes are proteins. There are a few RNA enzymes known as ribozymes exist. Proteins are all coded in DNA in the nucleus.
Regulating the manufacture of is the function of RNA?
Regulating the manufacture of proteins is the function of RNA. RNA carries instructions from DNA to the ribosomes, where proteins are made. This process is essential for cell function and overall organism development.
What is ribosomes function?
RibosomesProduces proteins.
Are DNA and RNA enzymes?
No, DNA and RNA (of which there are several types) are nucleic acids. All enzymes (if one adheres to the strict definition of the term) are proteins. Proteins are made of sequences of amino acids (coded for by nucleic acid genome) joined by peptide bonds or are polypeptides until they adopt their functional shape i.e. become enzymes and can act on specific substrate molecules. DNA is the genetic code (i.e. 'the stuff of genes') for most organisms, some viruses have an RNA genome. Summary - DNA/RNA contain the instructions to build proteins.
What are the Examples of intra cellular enzymes?
RNA/DNA polymerases - Reverse Transcriptase. Helicase. Binding proteins. Enzymes simply act on a substrate - there are tonnes.
Is polymerase A Protein?
RNA and DNA polymerases are enzymes and hence, they are proteins.
How does DNA function in a living cell?
DNA serves as the genetic blueprint of a cell, containing the instructions for building and maintaining an organism. It is transcribed into RNA, which is then translated into proteins, the workhorses of the cell. DNA replication ensures proper cell division and inheritance of genetic material.
What does DNA and RNA ultimately construct?
DNA is transcribed into RNA which is translated into proteins. Only a small percentage of DNA and RNA become proteins. Some of the time the process stops after DNA is transcribed into RNA.
Which nucleic acid does not carry out its function in the ribosome?
DNA does not carry out its function in the ribosome. DNA's main function is to store genetic information, which is then transcribed into messenger RNA (mRNA) to be translated in the ribosome to produce proteins.
What is the primary function of RNA inside a cell?
The primary function of RNA in a cell is to transfer genetic information from the DNA to the ribosomes, where it is used to synthesize proteins. RNA also plays a role in gene regulation and cell signaling.
Are bio-catalysts always proteins?
There are a few RNA catalysts are known, but the majority is only proteins. Biochemical reactions are speed by enzymes by lowering the activation energy. Enzymes like other proteins are coded in DNA.
