Explainthe structural properties of DNAand the role of DNA in hereditypassing of traits to offspring and protein synthesis production of protein
AssessmentDiagram and explain the role of DNA in heredity : DNA replication replicating DNA and protein synthesis which includes producing mRNA from transcription DNA translation making protein using tRNA and ribosomes (rRNA)
ExplainMendels laws of heredity• the Law of Segregation and• the Law of Independent AssortmentThe Law of Segregation states that the members of each pair ofalleles separate when gametes are formed. A gamete will receiveone allele or the other.The Law of Independent assortment states that two or more pairsof alleles segregate independently of one another duringgamete formation. And how can the laws can be used to determine the traits of possible offspring
AssessmentUse Mendels laws to predictthe potential offspring of two parents: Both phenotype and genotype
Explain possible causes ofchromosomalmutationsand their effects ongenetic variation
Assessment Name human chromosomal disordersSickle cell anemia Down Syndrome and describe the cause and symptoms of each Cystic Fibrosis

Messenger RNA (mRNA)Takesinstructions (a message)for making proteins from theDNA in the nucleusto theribosomes (rRNA) in the cytoplasm rRNA
Ribosomal RNA (rRNA)• The assembly line for producing proteins, bonds amino acids together
Transfer RNA (tRNA)• Supplies amino acids to the ribosomal RNA (rRNA)
TranscriptionWhen enzymes make an mRNA copy of a section of DNA (gene) RNA gene
Sections of gene that are expressed ExonsSections of a gene that are NOT expressed Introns Not expressed expressed
codon / base / amino acid base• A group of three nitrogenous _____s in amino a gene that code for an ______ acid is codon called a ______
protein AminoTranslation tRNA acidAfter transcription, mRNA rRNA goes to the ribosome and begins a process which converts mRNA mRNA code into a protein
