1. DESIGNER GENES GENETICS REVIEW

2. QUESTIONS? 1) WHAT IS GENETICS? 2) WHAT ARE GENES? 3)WHAT ARE CHROMOSOMES? 4)WHAT IS DNA? 5)HOW DOES A BABY GET HER OR HIS GENES? 6)HOW MANY CHROMOSOMES WILL EACH NEW BABY HAVE? 7)WHAT IS HEREDITY? 8)WHAT IS A TRAIT? 9)HOW IS A BABY’S SEX DETERMINED?

3. CHROMOSOME - A THREADLIKE STRUCTURE OF NUCLEIC ACIDS AND PROTEIN FOUND IN THE NUCLEUS OF MOST LIVING CELLS, CARRYING GENETIC INFORMATION IN THE FORM OF GENES. DEOXYRIBONUCLEIC ACID (DNA) : AN EXTREMELY LONG MACROMOLECULE THAT IS THE MAIN COMPONENT OF CHROMOSOMES AND IS THE MATERIAL THAT TRANSFER GENETIC CHARACTERISTICS IN ALL LIFE FORMS, CONSTRUCTED OF TWO NUCLEOTIDE STRANDS COILED AROUND EACH OTHER IN A LADDER LIKE ARRANGEMENT WITH THE SIDEPIECES COMPOSED OF ALTERNATING PHOSPHATE AND DEOXYRIBOSE UNITS AND THE RUNGS COMPOSED OF THE PURINE AND PYRIMIDINE BASES ADENINE, GUANINE, CYTOSINE, AND THYMINE GENE: A DISTINCT SEQUENCE OF NUCLEOTIDES FORMING PART OF A CHROMOSOME, A UNIT OF HEREDITY THAT IS TRANSFERRED FROM A PARENT TO OFFSPRING AND IS HELD TO DETERMINE SOME CHARACTERISTIC OF THE OFFSPRING.

4. DRAW A CHROMOSOME DRAW A GENE OF A CHROMOSOME DRAW A DNA STRIP OF THE GENE

5. GENES AND HEREDITY WHAT IS A TRAIT? WHAT IS A DOMINANT TRAIT? WHAT IS A RECESSIVE TRAIT? WHAT IS A GENOTYPE? WHAT IS PHENOTYPE? WHAT DOES HOMOZYGOUS MEAN? WHAT DOES HETEROZYGOUS MEAN?
