can somebody please explain the relationship between

Question

the structure of DNA, protein
structure and the phenotype of an
organism and

the relationship between DNA chromatin and chromosome

Answer 1

Since this is not my area of expertise, I searched Google under the key words "DNA chromatin chromosome" to get these possible sources:

http://www.ndsu.nodak.edu/instruct/mcclean/plsc431/eukarychrom/eukaryo3.htm
http://staff.um.edu.mt/acus1/03Nucleus.pdf
http://www.biology.arizona.edu/cell_BIO/tutorials/cell_cycle/cells1.html
http://en.wikipedia.org/wiki/Chromosome
http://www.rothamsted.ac.uk/notebook/courses/guide/chromo.htm

For the first question, I used "DNA 'protein structure' phenotype" as key words to find these sources:

http://plato.stanford.edu/entries/genotype-phenotype/
http://homepages.which.net/~gk.sherman/gaaaaaad.htm
http://www.scribd.com/doc/391114/Bioinformatics-Lookup-Table
http://www.estrellamountain.edu/faculty/farabee/BIOBK/BioBookDNAMOLGEN.html

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.

I hope this helps. Thanks for asking.
