BIO 107 EXAM 3 STUDY GUIDE
The law of segregation of alleles during meiosis is caused by the fact that __________.
- Correct Answers -homologous chromosomes are separated during meiosis I and only
one homologue ends up in each gamete
During leading strand synthesis the polymerase synthesizes the daughter strand in the
same direction as the movement of the helicase. This statement is: - Correct Answers -
True
Which of the following proteins help(s) to keep the parental DNA strands apart while
they are being replicated? - Correct Answers -Single strand binding protein
A bacterial cell has a nonsense mutation in DNA pol I that eliminates all of its functions.
If this cell were to enter into replication, what would be the final product you would
observe? - Correct Answers -Two bacterial chromosomes with leading daughter
strands, many Okazaki fragments, and a combination of RNA and DNA in each duplex.
Eukaryotic cells require telomerase to complete the replication of their chromosomes
because telomerase removes the RNA primers at the ends of the eukaryotic
chromosome during replication. This statement is: - Correct Answers -False
A researcher discovers that E. coli has the ability to complete replication, but it has a
DNA mutation rate 100 times higher than normal. Which of the following is the most
likely cause of this observation? - Correct Answers -The proofreading mechanism of
DNA polymerase III was not working
In a bacterial cell, a replication fork stops once it reaches the origin of replication a
second time. This statement is: - Correct Answers -False
Hamsters are diploid organisms with 44 chromosomes. How many chromosomes will be
found in a daughter cell at the conclusion of Meiosis I? - Correct Answers -22
Density-dependent inhibition occurs when crowded cells stop dividing. This statement
is: - Correct Answers -True
During lagging strand synthesis only one primer is required. This statement is: - Correct
Answers -False
A cell has 8 chromosomes and undergoes mitosis. In anaphase, how many
chromosomes does this cell have? - Correct Answers -.
