DETAILED ANSWERS (VERIFIED ANSWERS) ALREADY
GRADED A+
Phenotype Ans✓✓✓observable trait
genotype Ans✓✓✓set of alleles for a trait carried by an organism
The Central Dogma Ans✓✓✓DNA to Phenotype
Transcription Ans✓✓✓Dna to Rna
Translation Ans✓✓✓RNA to protien
sickle cell anemia Ans✓✓✓mutant for hemoglobin
What two proteins are in hemoglobin Ans✓✓✓alpha and beta
Which hemoglobin protein is mutated in sickle cell anemia?
Ans✓✓✓Beta protein
What happens when the beta protein is mutated in sickle cell anemia?
Ans✓✓✓-low oxygen
-distorts cell shape
,-fragile cells
-cells block flow in capillaries
Biotechnology Ans✓✓✓use of recombinant DNA technology and
molecular techniques to make products
Genetic Transmission Ans✓✓✓transmission of genetic material
between parental and daughter cells (must be precise)
Genetic transmission in prokaryotes Ans✓✓✓-Lack of nuclear envelope
and membrane bound organelles
-nucleoid (bacterial chromosome)
-circular
-attached to cell membrane
-DNA replicates and splits to daughter cells
Genetic transmission eukaryotes Ans✓✓✓membrane bound organelles,
chromosomes in nucleus, and the centrioles are important
Centrioles Ans✓✓✓Component of centrosomes, involved in organizing
spindle fibers

homologous pair, this is an exception
Locus Ans✓✓✓position of a gene
Alleles Ans✓✓✓different forms of a gene
Formation of gametes Ans✓✓✓the exception of mitosis because they do
not form through mitosis
Interphase Ans✓✓✓chromosomes uncoiled as chromatin
