- None of the above are found in our microbiomes
Mitochondrial genomes
Identify the WRONG statement below:
- DNA serves as a template during transcription to produce mRNA
- mRNA is a double-stranded copy of a gene used in translation
- mRNA serves as a template during translation to synthesize proteins
- Gene expression is crucial for protein production from genes
- Gene expression can be regulated by non-coding DNA
mRNA is a double-stranded copy of a gene used in translation

All of the above
Which of the following statements is FALSE?
- Proteins vary in the lengths of their sequences
- Disease mutations are generally dominant
- Individuals vary in the number of copies of a gene they have
- Centromere locations in chromosomes are not fixed among species
- Genes vary in the number of disease mutations
Disease mutations are generally dominant
Which of the following types of mutations ALWAYS leads to a disease?
- Nonsynonymous mutations
- Mutations in non-coding DNA regions
- Insertion of a DNA segment
- Deletion of a DNA segment
- None of the above
, None of the above
Which genotypes could lead to a disease when dealing with a recessive
mutation?
- Only homozygous recessive (aa)
- Only heterozygous (Aa)
- Only hemizygous (*a)
- Genotypes aa and *a
- Genotypes Aa and aa
Genotypes aa and *a
What could cause a beneficial mutation to be eliminated from a population?
- Random genetic drift
- By turning into a maladaptation
- Migration to a new environment

All of the above
What is the most common effect of new nonsynonymous mutations?
- They are detrimental
- They are beneficial
- They are neutral
- They are X-linked
- They are Y-linked
They are detrimental
Why do we observe more disease mutations than expected on the X
chromosome?
- The presence of only one active copy of X-linked genes
- The X chromosome has more than the expected number of genes
