DNA and RNA questions?

1. Usually all living cells of the same organism have the same exact DNA. But the cell type determines which genes are actually expressed.\n\n2. Eukaryote are more complex cells and have a longer time between transcription and a a functional protein. They use repression, signal cascades, phosphorylation, etc. A prokaryote has simpler regulation because transcription itself is usually the regulation.\n\n3. Vertebrates have 4 groups of hox genes, fruit flies only have one group. Look at the way the hox genes are expressed in development and what specifically they do (Sorry I can't give a more direct answer, I don't remember enough of my animal biology.)\n\n4. Polyploidy generally makes plants bigger, this makes their fruit bigger also. Another advantage is manipulation of fertilization. For example: seedless watermelon is produced by crossing a diploid with a tetraploid to get an infertile triploid. The embryos abort in the triploid and fail to form mature seeds.

1) both are nucleotide polymers\n2) contain cytosine, guanine and adenine\n3) made up of a sugar-phosphate backbone with nitrogenous bases\n4) code for biologically important information\n5) are stable\n6) capable of precise replication\n7) capable of incorporating mutations

you can read up on it here\n\nhttp://en.wikipedia.org/wiki/DNA\n\nbut even better would be to buy related books and take related courses

Adenine, Guanine, Cytosine, and Thymine

The phosphate in the backbone is the same. The difference (other than uracil in RNA and thyamine in DNA) is the sugar group. RNA has ribose, while DNA has deoxyribose. Deoxyribose has one less hydroxyl group.

Deoxyribonucleic acid (DNA) is a nucleic acid —usually in the form of a double helix— that contains the genetic instructions specifying the biological development of all cellular forms of life, and most viruses. DNA is a long polymer of nucleotides and encodes the sequence of the amino acid residues in proteins using the genetic code, a triplet code of nucleotides\n\nhttp://en.wikipedia.org/wiki/Dna

They both have to do with RNA... I had this on a bio quiz but I forgot...\n\nMRNA: RNA transcribed from the DNA making up a gene. It transmits genetic information from the nucleus to the cytoplasm, where it directs the synthesis of proteins.\n\nTRNA: RNA molecules that carry amino acids to sites on ribosomes where proteins are synthesized.

Usual,DNA is double helix (A form).DNA form include: A form, B form,....,Z form.DNA structure :\n base\n phosphast                 -----> nu ---->DNA\n sugar(desoxyrybonucleic)\n You can look at Nobelprizes.org

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.

its deoxyribose:  DNA is an acronym for deoxyribo-nucleic-acid\nwhereas; RNA stands for ribo-nucleic-acid, and contains ribose, instead of deoxyribose.

DNA and RNA can really be classified into one category and proteins into another.  Proteins have subunits of amino acids, which are determined by sets of three DNA bases (A, T, G or C).  There are 20 amino acids that can be incorporated into all of the proteins in all the organisms in the world.  DNA and RNA are composed of nucleic acids.  DNA uses A,T,G and C, whereas RNA uses A, U, G and C.  DNA is typically double stranded, whereas RNA is single stranded.  Both DNA and RNA bases are made up of a sugar, a phosphate group and a base.  One major difference between DNA and RNA chains is that DNA uses the sugar deoxyribose whereas RNA uses ribose -- these are both cyclic 5-carbon sugars, the only difference is some side groups hanging off the main chain and their orientation.  DNA's the stuff that your chromosomes are made up of -- it's the storage unit for all of your genetic information.  RNA is used in the transport of this information outside of the nucleus into the cytoplasm, where it is then involved in the process that links amino acids together into the final protein (this whole sequence was originally dictated by DNA).

the first one is RNA. You can tell by the U at the end of the sequence
