Cuts double stranded RNA to make small RNAs

Front

How do researchers deal with introns when expressing eukaryotic genes in bacteria?

Back

Reverse Transcriptase PCR (RT-PCR)

Front

What type of mutations in proto-oncogenes are associated with cancer?

Back

Gain-of-Function mutations

Front

What type of mutations in tumor suppressor genes are associated with cancer?

Back

Loss-of-Function mutations

Front

What is a microRNA (miRNA)?

Back

A small non-coding RNA molecule that regulates gene expression by binding to complementary mRNA.

Front

What is the role of histone methylation in gene regulation?

Back

Histone methylation can either activate or repress gene expression depending on the context.

Front

What is the difference between DNA methylation and histone acetylation?

Back

DNA methylation typically represses gene expression, while histone acetylation generally promotes gene expression.

Front

What is the significance of introns in eukaryotic genes?

Back

Introns are non-coding sequences that can regulate gene expression and alternative splicing.

Front

What is the purpose of CRISPR technology?

Back

CRISPR is used for gene editing, allowing for precise modifications to DNA.
