Mastering Gene Expression and Gene Technologies

1️⃣Gene mutations can result in a different amino acid sequence and protein structure, leading to altered protein function and potential diseases.

2️⃣There are six types of gene mutations: addition, deletion, substitution, inversion, duplication, and translocation.

3️⃣Stem cells have the ability to divide and differentiate into different types of cells, playing a crucial role in cell specialization.

4️⃣Transcription factors regulate gene expression by binding to DNA and initiating or inhibiting transcription of specific genes.

5️⃣Epigenetics involves heritable changes in gene function without altering the DNA sequence and can be influenced by environmental factors.

What are the consequences of gene mutations?

—Gene mutations can lead to altered protein function, potentially causing diseases like cancer.

What are the different types of gene mutations?

—There are six types of gene mutations: addition, deletion, substitution, inversion, duplication, and translocation.

How do stem cells contribute to cell specialization?

—Stem cells can divide and differentiate into different types of cells, providing the foundation for specialized cells in multicellular organisms.

How do transcription factors regulate gene expression?

—Transcription factors bind to DNA and either initiate or inhibit the transcription of specific genes, controlling gene expression.

What is epigenetics?

—Epigenetics refers to heritable changes in gene function that are not caused by alterations in the DNA sequence, influenced by environmental factors.
