Explain how red color blindness is inherited.
Why is it more common in males than females?
Topic 3 - $400 Question
Click to see answer
Red color blindness is controlled by the recessive
allele in the x chromosome. For a female to be colorblind, she
must inherit two recessive alleles whereas a male only
need to inherit one recessive gene.

Name and describe the 3 mendelian pattern of
inheritance.
Topic 3 - $500 Question
Click to see answer
1)Autosomal Dominant-Dominant inheritance occurs when an abnormal gene from one parent causes disease even though the matching gene from the
other parent is normal. Autosomal Recessive-both matching genes must be
abnormal to cause disease.
2)Sex-linked Recessive-Sex-
linked diseases are passed down through families through one of the X or Y chromosomes.

If scientists wish to add a eukaryotic gene to a bacterium in order to get the bacterium to make the
eukaryotic protein, they usually produce the DNA for this gene by
a. copying the mRNA for the protein with reverse transcriptaseb. exposing the bacteria to mutagens and then selecting for those
that make the needed proteinc. isolating the correct eukaryotic gene and then removing the
introns from the DNAd. ligating the string of oligonucleotides isolated from eukaryotic
DNAe. sequencing the amino acids in the protein and then constructing
a piece of DNA to code for them
Final Jeopardy Question
Click to see answer
A.
The scientists use mRNA because it does not have introns. They use reverse transcriptase to make complementary DNA or cDNA. The cDNA is then added to the plasmid and introduced to the bacteria.
