- Is used to investigate when and where proteins are expressed
- Examine the involvement of proteins in metabolic pathways
- All of the above
-All of the above
True or False
Alternate splicing enables a cell to manufacture different versions of a protein by removing exons and retaining introns.
-False (combing exons)
True or False
Viral genomes sizes typically range between 100-1000 Kb.
-True
True or False
Bacterial genomes sizes range between 1-10 Mb.
-True
Another word used to describe for Missense mutation.
- Nonsynonymous Mutation
- Null Mutation
- Silent Mutation
- Termination Mutation
-Nonsynonymous Mutation
________ is a mutation characterized by changes in the codon specifying an amino acid into a stop codon, resulting in premature polypeptide chain termination.
- Null Mutation
- Synonymous Mutation
- Frameshift Mutation
- Nonsense Mutation
-Nonsense Mutation
True or False
The degree to which a mutation alters the phenotype depends upon where in the gene the change occurs, and how the mutation affects the conformation, activity, or abundance of an encoded protein.
-True
They are the parts of mRNA that remain and are translated?
- Transposons
- Introns
- Exons
- microRNA
-Exons
Embryonic hemoglobin is composed of?
- 2 gamma chains and 2 alpha chains
- 2 zeta chains and 2 epsilon chains
- 2 alpha chains and 2 beta chains
- 2 epsilon chains and 2 alpha chains
-2 zeta chains and 2 epsilon chains
They are otherwise known as “jumping genes.” can alter gene function in several ways like disrupting the site they jump from, shut off transcription of the gene they jump into, or alter the reading frame of their destination if they are not a multiple of three bases.
- Pseudogenes
- Transposons
- Introns
- Exons
-Transposons
______ is an alteration in a DNA coding sequence that results in amino acid replacement in polypeptides.
- Missense Mutation
- Nonsense Mutation
- Synonymous Mutation
- Frameshift Mutation
-Missense Mutation
They are parts of mRNA that are removed and are otherwise known as intervening sequences.
- Exons
- Transposons
- microRNA
- Introns
-Introns
The term “epigenetic” denotes?
- Outside the protein
- Inside the protein
- Outside the gene
- Inside the gene
-Outside the gene.
_______ is a change in a DNA sequence that is rare in a population that may or may not be beneficial.
- Polymorphism
- Variant
- Mutation
- Isoform
-Mutation
True or False
A mutation is an alteration in the DNA sequence that is rare in a population and typically affects the phenotype.
-True
