DNA, RNA, and Protein Synthesis DNA -The species-particular DNA sequences produce the species-particular proteins -Genes code for proteins -Genes are long strands of DNA of chromosomes WHAT IS DNA? -DNA is genetic code -Instructions for heredity -Components of genes -Director of protein synthesis -A type of nucleic acid -A type of organic compound -A polymer {a compound made of repeating subunits} DNA'S PROPER NAME IS -Deoxyribonucleic acid -Consists of a ribose sugar with a "missing oxygen" (thats the de-oxy part) -And it's found in the nucleus of eukaryotic cell STRUCTURE OF DNA -A nucleotide of DNA is the base unit -A nucleotide consists of a phosphate, a sugar, and a nitrogen base DNA IS A DOUBLE STRAND -The nitrogen bases have compliment partners

4/2/13 1:14 PM DNA Deoxyribose Double Stranded (Double Helix) Nitrogenous bases (Cytosine, Guanine, Adenine, Thymine) RNA Ribonucleic Single Stranded Nitrogenous bases (Cytosine, Guanine, Adenine, Uracil) Both have phosphate Cytosine = Guanine Adenine = Thymine DNA Replication is semi conservative. DNA Replication happens during interphase. One strand determines the sequence of the other strand. DNA polymerase copies DNA strands in the 5?->3? direction. Transcription ? The first step of gene expression, in which a particular segment of DNA is copied into RNA by the enzyme, RNA polymerase. Translation ? The process through which cellular ribosomes manufacture proteins. In DNA, T=A G=C In RNA, T=A G=C A=U Translation occurs in the cytoplasm.
