pls use the term gene, mRNA , ribosomes and polypeptide inn ur answers pls.

Genotype is encoded by gene in DNA. Gene in DNA will be transcripted into mRNA. Then mRNA will be translated into polypeptide(protien). (Ribosomes play important role in transaltion.) So bacteria with different genotypes will have different protein --> different phenotypes.

ribosomal RNA doesn't actually do any of those. it's a structural part of ribosomes. it's the enzymes (helicase, topoisomerase) that unwind and separate the dna strand. As for the codes for the aminoacid sequence... they're coded by mRNA.

The above is not complete. Don't have time to go into details, but check out this website:\n\nhttp://www.learner.org/channel/courses/biology/textbook/cancer/index.html\n\nI suggest reading the entire chapter if you don't have time for that, I suggest the section on Tumor Biology and the treatment section

The DNA which carries genetic information in cells is normally packaged in the form of one or more large macromolecules called chromosomes.\n\nA chromosome, from the Greek χρώμα (color) and σώμα (body) is, minimally, a very long, continuous piece of DNA (a single DNA molecule), which contains many genes, regulatory elements and other intervening nucleotide sequences.

DNA has four bases, the ones you are referring to as chemicals. The names of these bases are Adenine (A), Thymine (T), Cytosine (C) and Guanine (G). In RNA all these bases are also present except T where it is replaced by Uracil (U). So when information is copied from DNA to RNA (mRNA specifically) C pairs with G, G pairs with C, T pairs with A and A pairs with U (since there is no T but U in RNA).\n\nBesides that the chemical composition of DNA (Deoxyribonucleic Acid) is a Phosphate group, a base(the four bases) and a sugar (Deoxyribose). These three parts together form a nucleotide. A nucleotide without a phosphate group is called a nucleoside. The 'chemicals' you are looking for are Adenine, Thymine, Cytosine and Guanine.

Go to "protein" on wikipedia ( put, protein, in address bar ) then scroll down to "synthesis", for the process. It is too  long a story for my typing skills. The wiki article is not too technical.

All contain carbon, oxygen, hydrogen and nitrogen.\nAmino acids form proteins, while DNA and RNA are formed from nucleic acids.\nDNA stores the genetic code, mRNA transfers portions of that code to the cytoplasm, and is the transcript from which amino acids are strung together, in a specific pattern, to form the new peptide or protein.

Phenotypes: AB+ or AB-\n\nAntigens: A and B\n\nGenotypes: AB (+ or -)\n\nThanks micro_girl.  I should have made that more clear.  A and B are separate proteins, and when they are both present the resulting phenotype is AB.  Sorry if my original answer was misleading.  I fixed it.

Proteins are macromolecules. They are constructed from one or more unbranched chains of amino acids; that is, they are polymers. A typical protein contains 200–300 amino acids but some are much smaller (the smallest are often called peptides)\n\nWe know Proteins are Broken down from Protease and can be then broken further down into amino acids.\n\nWhy do we need Proteins for?\nWell ahve a look.\n\nMotion and locomotion of cells and organisms depends on contractile proteins. [Examples: Muscles] \nThe catalysis of all biochemical reactions is done by enzymes, which contain protein. \nThe structure of cells, and the extracellular matrix in which they are embedded, is largely made of protein. [Examples: Collagens] (Plants and many microbes depend more on carbohydrates, e.g., cellulose, for support, but these are synthesized by enzymes.) \nThe transport of materials in body fluids depends of proteins. [See Blood] \nThe receptors for hormones and other signaling molecules are proteins. \nProteins are an essential nutrient for heterotrophs. \nThe transcription factors that turn genes on and off to guide the differentiation of the cell and its later responsiveness to signals reaching it are proteins.\n\n4) Strcuture of a Protein\n\nProteins fold into a variety of 3-dimensional shapes. Experiments to unfold and refold proteins have shown that the amino acid sequence itself contains all the instructions needed for proper folding. Scientists have searched for rules governing folding but have found no reliable way to predict a 3-dimensional structure from a simple sequence.\n\nKnowing a protein's sequence does help, however. Having determined \n\n3) Importance of Proteins\nThere are proteins that build muscle, transport protein that carry nutrients, enzymes that 搄ump start?cellular activity, protein hormones involved in regulating metabolism, structural proteins like collagen, and special proteins needed for antibody production. Proteins are thus involved in all body functions, and are nessacary for health.\n\nProteins are large molecules that are made up of smaller chains of peptides. Peptides are chains of amino acids that are biochemically bonded together. There are about 50 amino acids is a single peptide chain. During normal digestion the proteins we take in are broken down into its simplest form (amino acids). These amino acids are then absorbed by the body and made back into proteins that the body needs. As we saw before proteins are crucial to a variety of body functions and structure. This is why everybody need to include protein foods in their diet\n\n\nSort of answer Your Question?

Too many to list and explain here, without copying and pasting  --and why should I do all your uni work for you? ;-)\n\nI will recommend a couple of good text books through.  Well worth a purchase or just get them on loan from your library...\n\nAlberts et al, Molecular Biology of the Cell\nStryer, Biochemistry\n\nIt's been since I bought mine.  Think I got editions 2 & 7 back in 1996 and I know both have been updated a couple of times since.  These are still a GREAT basic resourse for this sort of question.
