Modern synthesis of evolution how evolution works at level of phenotypes, genes and population. Cell somatic cells: most cells in body except sex cells gametes: sex cells cytoplasm: complex mix of membrane, and tiny structures called organelles nucleus: contains hereditary material chromosomes also called head office. Chromosomes paired-rod shaped structures in cell nucleus containing genes that transmit traits from gene to gene. Whole bunch of dna pull out and you can see the genetic code deoxyribonucleic acid blueprint. 4 nucleotide bases: adenine (a, guanine (g, thymine (t, cytosine (c) A always bonds with t, and g always bonds with c. Worker/helper some functions: dictate synthesis of proteins that perform variety of functions such as which protein gets made regulate expression of other genes. 2: work with ribosomes (factory) that manufacture proteins. 4. transport amino acids to ribosomes for creation of proteins, brings in building blocks: rna does have thymine, instead there is uracil www. notesolution. com.
