What do you call the changes in a person’s DNA that occur after conception and are not inherited?
Hereditary mutations
Acquired mutations
Genetic mutations
Point mutations
A gene change that occurs in a germ cell (an egg or a sperm) and is then incorporated into every cell in the developing body of the new organism.
Hereditary mutations
Acquired mutations
Genetic mutations
Point mutations
What do you call the process by which a section of DNA is used to produce a single-stranded RNA molecule?
Transcription
Translation
Translocation
Transversion
It is the basic physical and functional unit of heredity
DNA
RNA
Gene
Chromosome
It is the process whereby genetic information coded in messenger RNA directs the formation of a specific protein at a ribosome in the cytoplasm.
Transcription
Translation
Translocation
Transversion
What are proteins made of?
Nucleic acids
Fatty Acids
Nucleotides
Amino Acids
What do you call the three-base sequence on messenger RNA that codes for a single amino acid?
Bases
Triplets
Codon
Nucleotides
A ___________ mutation changes the DNA sequence by adding one or more nucleotides to the gene.
Insertion
Deletion
Substitution
Duplication
A ___________ mutation changes the DNA sequence by removing at least one nucleotide in a gene.
Deletion-Insertion
Deletion
Substitution
Duplication
What do you call a type of mutation that occurs when a stretch of one or more nucleotides in a gene is copied and repeated next to the original DNA sequence.
Deletion
Substitution
Duplication
Insertion
Instead of causing a change in one amino acid, the altered DNA sequence results in a STOP signal that prematurely signals the cell to stop building a protein. What do you call this type of substitution?
Missense
Nonsense
Nonsense and Missense
None
It is a type of substitution in which the nucleotide changes result in the replacement of one protein building block (amino acid) with another in the protein made from the gene.
Missense
Nonsense
Both A & B
None
