DNA & RNA 1) DNA Basics 2) DNA Structure & Function 3) DNA Replication
4) RNA Structure & Function 5) Comparing DNA & RNA

Organization of DNA inside the cell:
Nucleus Chromosome DNA Genes (top) 1) DNA Basics DNA stands for Deoxyribonucleic acid, and is the instructions for making proteins. DNA is stored in the nucleus. It is wrapped tightly around proteins called histones to form structures called chromosomes. DNA contains many genes, each controlling the production of one protein. (bottom)

STRUCTURE of DNA: 2) DNA Structure & Function (top)
Shade or circle the following parts in the given color: Green= Phosphate Group Red= Sugar Blue=Nitrogenous bases Yellow=Nucleotide Purple= Sugar-Phosphate backbone DNA has a DOUBLE HELIX shape!!!
4
FUNCTION of DNA: 2) DNA Structure & Function (bottom)
DNA stores the genetic material. internal code of nitrogenous bases double stranded sugar-phosphate backbone protect the code coiled tightly to allow for more surface area meaning more room to store genetic code DNA passes traits to the next generation. nitrogen bases are complementary A and T pair together G and C pair together weak hydrogen bonds hold bases together- allow for ease during replication

#1 #2 DNA Replication 3) DNA Replication (top)
Color the following in picture #1: Green= Parent Strand Yellow= Complementary Strand #1 Outline the following: in picture #2: Red = Leading strand Blue = Lagging #2

3) DNA Replication (bottom)
LEADING STRAND 3. Elongation enzyme DNA polymerase reads template strand and continuously adds new nucleotides that are complementary to the parent strand 1. DNA unwinds with help of an enzyme, helicase, this breaks weak hydrogen bonds between bases 2. The enzyme primase attached to the parent strand, this helps bind (attach) new nucleotides 4. DNA primers are removed & DNA ligase adds sugars and phosphates in gaps made by fragments 5. DNA Termination LAGGING STRAND 3. DNA primase adds more primers, DNA is elongated in short segments (Okazki fragments) by DNA polymerase. 6. DNA repairs itself

4) RNA Structure & Function (top)
Types of RNA: mRNA tRNA rRNA
8
4) RNA Structure & Function (top)
Type of RNA: Function: mRNA “messenger” makes a copy of DNA in the nucleus travels from nucleus cytoplasm ribosome bases in mRNA are read in sets of 3 bases called codons rRNA “ribosomal” “home” of protein synthesis= mRNA brings code, tRNA brings amino acids and rRNA puts the two together to make protein tRNA “transfer” gathers amino acids travels to the ribosome contains a set of 3 bases in tRNA (anticodon)
