Why are nucleotides a good molecule to make DNA out of, while amino acids are good for making proteins?
A good answer will include:
-how nucleotides compare to amino acids in terms of diversity of shape and feel
-how the structure and funciton of DNA compares to the structure and function of proteins
-what is the 'job' of DNA? why are the nucleotides good for allowing DNA to carry out its functions? what is the job of a protein? how does being built out of amino acids help proteins function?
Homework Answers
Neucleotides are the basic unit unit of DNA. Nucleotides are phosphoric acid esters of nucleosides. with phosphate at the position C-5. the nucleotide can have one, two or three phosphate group designated alpha, beta and gamma for the first, second and third respectively.
Neucleotides are found primarilt as the monomeric units comprising the major nucleic acid of the cell, RNA and DNA. however they are also required for other important functions within the cell.
The nucleotides are the basic unit of nucleic acid. Therefore nuclic acids are also called as polynucleotides. Nucleotides are the phosphate esters of the nucleosides and made of three components
1. a base that has a nitrogen atom
2. Afive carbon sugar
3. An ion of phosphoric caid
On the otherhand the aminoacids are the basic unit of proteins which are made up of an amino group, a carboxyl group, a hydrogen atom and a distinctive side chain, all bounded to a carbon atom, the alpha carbon
the structure of aminnoacid is common to all aminoacids except proline. The R group or side chain attached to the alpha carbon is different in each amino acid. amino acid can act as acids or bases when dissolved in water.
The job of DNA to form a genetic code for the organism and translate the code into the function. DNA is important for inheritance, coding for proteins and the genetic instruction guide for life and its processes.polynucleotides are formed by the condensation of two or more nucleotides. the secondry structure is the three dimensional structure of the polynucleotide strand or strands. For the DNA, the most important secondry stucture consists of a double helix held together with a hydrogen bond. The Three base pair compostion forms a codon and make one amino acid. The amino acids forms peptide by making peptide bond between the amino acids. The amino acids forms the protein allow it to do many biological fuctions.

What are the three functional groups that comprise a nucleotide? What do nucleotides have in common with amino acids or simple sugars? When the structure of DNA was first elucidated, many biologists quickly saw how this structure explained the passage of information from one generation to another. How does the structure of DNA explain generation-to-generation flow of information? In other words, give a brief description of the structure of DNA and tell how this structure allows for replication. Which of...

Transcription is the process of rewriting DNA. DNA molecules are made from 4 different nucleotides which acts as building blocks. These building blocks are adenine, thymine, guanine and cytosine. When put together in different chemical combinations they become directions for the functions of the cell molecules which are primarily proteins. When a certain protein is needed, the RNA polymerase enzyme will find the gene for that particular protein and makes an RNA copy of it. DNA and RNA have similar...

6) Proteins are composed of amino acids polymerized into long chains. The structure of a protein - that is, its overall shape and how the chains are "folded” around each other - is very important for its function. In an aqueous environment, in an active, folded state the hydrophilic amino acids in the protein are facing outwards exposed to the water and the hydrophobic amino acids are hidden away from the water in the core of the protein. In a...
