1 REPORTING CATEGORY 2

2 #21-PROTEIN SYNTHESIS

3 CHANGES TO DNA CODE

4 #18-STRUCTURE OF DNA

5 STRUCTURE OF DNA COMPONENTS OF NUCLEOTIDES: -deoxyribose sugar -phosphate group -nitrogenous bases: A,T,G,C

6 #11-PROTEIN SYNTHESIS

7 DNA  RNA  PROTEIN -DNA is transcribed to messenger RNA -Double stranded to single stranded nucleic acid -mRNA goes to ribosome to be translated into protein COMPLEMENTARY BASES DNA  DNADNA  RNA A=T A=U C=G T=A C=G

8 #26-MEIOSIS

9 CROSSING OVER DURING MEIOSIS -Segments of homologous chromosomes break and reattach at similar locations. -Results in new genetic combinations of offspring.

10 #4-DNA AND TECHNOLOGY

11 LOCATION OF GENES ON CHROMOSOMES -Karyotypes are charts used to show genetic disorders -Different species may share similar genetic sequences that may be spotted using mapped-out chromosomes

12 #13-MENDELIAN GENETICS

13 DIHYBRID CROSS - Looks at two traits that are independently assorted -Can use cross to determine probable genotypes and phenotypes

14 #38-MENDELIAN GENETICS

15 MONOHYBRID CROSS -Punnett squares are used to solve crosses -Dominant vs Recessive alleles -Heterozygous vs Homozygous -Genotype vs Phenotype

16 #49-GENETIC CODE

17 UNIVERSAL GENETIC CODE Almost all living organisms use same translation rules DNA  mRNA  protein

18 #30-GENETIC CODE

19 UNIQUE GENETIC CODES Sequences of nitrogenous bases lead to genetic variation among organisms.

20 #53-MEIOSIS

21 SEXUAL REPRODUCTION  Meiosis results in the formation of haploid cells.  Gametes formed are either egg or sperm cells.  Egg and sperm fuse to become a fertilized zygote.  Offspring will inherit equal amounts of genetic information from each parent.

22 #43-GENETIC CODE
