Thomas Hunt Morgan crossed pure-breeding red-eyed (females) with whit-eyed male flies. All the F1
generation had red eyes. When he crossed individuals in this F1 generation to each other, the F2
generation included both red and white-eyed flies. However, all the white-eyed flies in the F2 were
male. (All males are XY) - Correct Answer The gene for eye color must be located on a sex chromosome
If a hybrid f2 female is crossed with a white eyed male, what are the expected f3 phenotypes? - Correct
Answer 50/50
Calico cats display black and orange fur patches, are genetic mosaics and are exclusively female
because... - Correct Answer X chromosomes are randomly inactivated in the developing female embryo
During the formation of gametes, if nondisjunction of one chromosome pair occurred during Meiosis I,
then... - Correct Answer the tetrads did not separate and all these particular chromosomes ended up in
one daughter cell
If parts of chromosomes 5 and chromosome 12 broke off and swapped places, this change would be.. -
Correct Answer translocation
A woman with blood genotype |aiRr (type A+) and a man with blood genotype |Birr (type B-) have
children together. What would be the outcome? - Correct Answer |BiRr
If you obtain results that indicate phenotypic ratios of 9:3:3:1 in the F2 generation, such ratios indicate...
- Correct Answer the genes controlling the traits obey the law of independent assortment
The bacteria transformation experiment of Griffith, and the virus transduction experiment conducted by
Hershey and Chase, convinced us that - Correct Answer the inherited information is contained in
deoxyribonucleotides
What is not true of DNA - Correct Answer there are 20 nucleotide monomers that can be used to
synthesize DNA
, A primer has been made using one strand of DNA as a template as shown below. Which enzyme made
this primer? - Correct Answer primase
What is not a part of DNA replication? - Correct Answer ribosomes polymerizing amino acids into
polypeptides
The lagging strand is the strand synthesized.. - Correct Answer in short segments in a direction away
from the replication fork
During the process of transcription in both prokaryotic or eukaryotic cells... - Correct Answer RNA is
synthesized
RNA is synthesized - Correct Answer RNA polymerase
What ways can eukaryotic pre-mRNA be modified? - Correct Answer removal of all introns
What is not involved in transcription? - Correct Answer codons in the mRNA
What statement is true about translation in prokaryotes? - Correct Answer Translation can begin while
transcription is not yet complete
As a ribosome moves along a mRNA molecule by one codon, what occurs? - Correct Answer The tRNA
that was in the A site is now in the P site/adjacent amino acids form covalent bond//adjacent amino
acids form covalent bonds
The role of the signal peptide is to... - Correct Answer Direct the developing polypeptide into the
ER//direct the developing polypeptide out of the cytoplasm
The DNA sequence in two people are compared and found to be different in one exon. However, they
have identical corresponding polypeptide. How could this change in the DNA be described? - Correct
Answer The nucleotide change might not have changed the amino acid used due to the redundant
nature of the genetic code
