Mutations occur (randomly) during...
Translation
DNA Replication
Transcription
All of the following are Chromosomal Mutations except:
Inversion
Translocation
Duplication
Insertion
What kind of mutation is a substitution?
Frameshift
Point
True or false: A deletion mutation can cause a frameshift.
True
False
How many sets(pairs) of chromosomes do humans have in the nucleus of each cell in their body?
100
46
48
23
During what phase of meiosis does crossing over occur?
Prophase l
Metaphase l
Anaphase l
Prophase ll
In meiosis, cell division takes place one time.
In meiosis, daughter cells are not genetically identical to the parent cell.
The process of mitosis produces 4 daughter cells with half the number of chromosomes.
Haploid cells are _______ and produced by the process of ________.
regular cells, mitosis
gametes, meiosis
regular cells, meiosis
gametes, mitosis
The addition of a single nucleotide to the DNA sequence causes a frameshift mutation.
In a frameshift mutation all of the amino acids before the shift are changed.
The nucleic acid sequence in mRNA is determined by
the order of amino acids in the protein
nucleotide sequence in DNA
nucleotide sequence in t-RNA
All of the Above
A nucleotide deletion in DNA replication
causes one amino acid of the protein to be incorrect
causes all of the amino acids of the protein to be incorrect
causes the amino acids inserted after the deletion to be incorrect
causes the amino acids inserted before the deletion to be incorrect
has no effect on the resulting protein
If a frameshift mutation causes a stop codon to be inserted into the DNA sequence
the resulting protein will not be affected
the phenotype will change but not the genotype
the resulting protein will be too short and non-functional
the resulting protein will be too long and non-functional
If a patient has a Trisomy disorder, how many TOTAL chromosomes do they have?
47
3
