Gene Expression and Gene Editing

What is gene expression?

• The process by which information from a gene is used in the synthesis of a functional gene product, such as proteins or RNA.

• The process of copying DNA to create a new gene.

• The process of editing genes to change their function

• The process of combining genes to create a new organism

Explain the process of transcription in gene expression.

• Transcription is the process of creating an RNA copy of a segment of DNA.

• Transcription is the process of creating a protein copy of a segment of DNA.

• Transcription occurs in the cytoplasm of the cell.

• Transcription only occurs in prokaryotic cells.

Explain the concept of gene regulation in gene expression.

• Gene regulation in gene expression refers to the control of the amount and timing of the appearance of functional gene products.

• Gene regulation is the process of altering the genetic information within a gene

• Gene regulation only occurs in non-coding regions of the genome

• Gene regulation involves the manipulation of DNA sequences to create new genes

What is the significance of gene expression in cell differentiation?

• Gene expression is essential for regulating the process of cell differentiation.

• Gene expression has no impact on cell differentiation

• Cell differentiation occurs randomly and is not influenced by gene expression

• Cell differentiation is solely determined by environmental factors

Discuss the role of epigenetics in gene expression.

• Epigenetics plays a crucial role in regulating gene expression by modifying the structure of chromatin and controlling access to specific genes.

• Epigenetics only affects gene expression in plants, not in animals

• Epigenetics has no impact on gene expression

• Epigenetics is only involved in gene expression during early development, not in adulthood

Explain the impact of mutations on gene expression.

• Mutations can impact gene expression by altering the sequence of DNA, which can lead to changes in the structure and function of the resulting protein

• Mutations only impact gene expression in non-coding regions of DNA

• Mutations have no impact on gene expression

• Mutations always result in an increase in gene expression

How does gene expression contribute to the development of diseases?

• Gene expression only contributes to the development of healthy cells

• Gene expression always leads to the prevention of diseases

• Gene expression can contribute to the development of diseases by producing abnormal or overproducing certain proteins.

• Gene expression has no impact on the development of diseases

How does gene expression play a role in the progression of cancer?

• Gene expression can contribute to the development of cancer by promoting the growth of abnormal cells

• Gene expression only leads to the prevention of cancer

• Gene expression has no impact on the progression of cancer

• Gene expression only affects healthy cells, not cancer cells

Explain the role of transcription factors in gene regulation.

• Transcription factors play a crucial role in controlling the expression of specific genes by binding to DNA and initiating or blocking transcription

• Transcription factors have no impact on gene regulation

• Transcription factors only regulate gene expression in non-coding regions of the genome

• Transcription factors are only involved in gene regulation during early development, not in adulthood

CRISPR can change DNA in humans and animals.  What did scientists look at to help them create CRISPR?

• sheep cloning

• common colds

• palindromic repeats

• bacteria fighting off viruses
