Document Summary
Dna in ec and pc the same. Unit 1: reading the blueprint: same basic subunits: a,t,g,c used to make dna sequence. Each dna molecule will contain 1000s of genes of codes, protein or rna molecules that have various functions in cell. Genes are sections of the dna molecule which contain info that"s transcribed into an rna copy. Genes in dna code for specific proteins. Central dogma: process of copying and interpreting genes into known proteins: dna rna protein. Francis crick (1950: proposed: info in dna specify sequence of bases in rna molecule specifies sequence of amino acids in protein dna can be copied multiple times into messenger mrna. Mrna transcribed from the nucleotide language of mrna into amino acid language of protein. Transition from dna mrna protein is the process of gene expression and requires the transcription of info encoded in dna rna. Dna: deoxyribose sugar, nitrogenous base (adenine, thymine, guanine, cytosine), phosphate double stranded.
