BIO400 Exam A+ Pass Solved Correct
UPDATED
Induced Allelic Conversion (IAC) - CORRECT ANSWER-technique that allows
for the conversion of one allele of a gene into another, typically to correct genetic
mutations or introduce desired traits.
Next-Generation Sequencing (NGS) - CORRECT ANSWER-Purpose: NGS
provides high-throughput sequencing data, enabling comprehensive analysis of
genomes, exomes, and transcriptomes.
Application: Useful for identifying genetic mutations, variations, or differences
between normal and diseased tissues. Can also be used to identify novel genes or
variants linked to diseases.
Example: Identifying mutations in cancer or exploring genomic diversity across
populations
Bisulfite Sequencing and Microarrays - CORRECT ANSWER-Purpose: These
methods analyze DNA methylation patterns, which are critical for regulating gene
expression.
Application: Explore how methylation affects gene expression in various disease
contexts, especially cancer.
, Example: Studying the silencing of tumor suppressor genes in cancer due to
hypermethylation.
PCR - CORRECT ANSWER-Purpose: PCR amplifies DNA or RNA (via RT-
PCR), enabling the detection of specific sequences or mutations.
Application: This is an essential technique for studying gene expression, detecting
mutations, and analyzing specific genomic regions.
Example: Detecting mutations in genes like BRCA1/BRCA2 for cancer risk
assessment or amplifying specific genes for sequencing.
RNA-seq - CORRECT ANSWER-Purpose: RNA-Seq provides an in-depth
analysis of the transcriptome, helping to measure gene expression and detect
splicing events or novel transcripts.
Application: Used for studying gene expression in different conditions, cell types,
or diseases. This method is also useful for detecting alternative splicing or post-
transcriptional modifications.
Example: Comparing gene expression profiles in cancer vs. normal tissues to
identify potential biomarkers or therapeutic targets.
ChIP-seq - CORRECT ANSWER-Purpose: ChIP-Seq helps study protein-DNA
interactions by identifying where transcription factors or histone modifications
bind in the genome.
