Question

Create three relevant questions that you would like answered or clarified about the role of DNA and chromosomes. Focus on the following areas as you generate questions: The cause and effect relationship between the genetic code and gene expression Mechanisms of gene regulation The role of DNA segments that do not code for proteins

Answer 1

Answer:

Why DNA is a suitable molecule for information storage?

What is the function of the genes in the DNA molecule?

What is the role of the chromosomes in the cell nucleus?

Explanation:

The DNA template is stable because this molecule forms a double helix where complementary strands simultaneously interact through multiple hydrogen bonds. Moreover, it is a structural arrangement that also makes the DNA resistant to enzymatic cleavage.  

The genes are the basic physical units of inheritance, whose main function is to contain the information necessary to synthesize structural and regulatory proteins. The gene expression is controlled through regulatory proteins known as Transcription Factors. Moreover, the DNA molecule also contains regulatory elements that modulate gene expression such as, among others, enhancer and promoter regions capable of activating transcription.  

The DNA information is organized into chromosomes that contain groups of linked genes. The chromosomes play a key role during cell division, where the genetic information is equitably inherited by the two daughter cells.
