Assemble a digital gallery of DNA diagrams and photographs. Your collection can and should include some the Web sites you visited during the DNA lessons. Choose diagrams and photographs that helped you most in your study of this chapter. In the gallery, you will illustrate both the structure and the makeup of the giant molecule. You should also include illustrations showing its location in the cell.

Question

You will include the following labeled and cited* items:

location of DNA in a cell
DNA structurer
DNA makeup
base pairing concept
genes and alleles
chromosome replication

Answer 1

Creating a digital gallery of DNA diagrams and photographs is a great way to visualize the complex structure and function of DNA. Below, I've outlined suggested items for your gallery, descriptions of each component, and citations for reputable sources you can use to find high-quality images. You will need to conduct your own searches for these images to assemble your gallery.

Digital Gallery of DNA

1. Location of DNA in a Cell

   • Description: A diagram showing the nucleus of a cell, where DNA is primarily located, along with a depiction of mitochondrial DNA in the mitochondria.
   • Image Source:
     • "Cell Structure - Cell Types and Function" at Cells Alive.
     • You can also check ScienceDirect.

2. DNA Structure

   • Description: An illustration of the double helix structure of DNA, highlighting its antiparallel strands and sugar-phosphate backbone.
   • Image Source:
     • "What is DNA?" at Nature Education.
     • Khan AcademyDNA Structure.

3. DNA Makeup

   • Description: A detailed diagram showing the nucleotide components of DNA, including the sugar (deoxyribose), phosphate group, and nitrogenous bases (adenine, thymine, guanine, cytosine).
   • Image Source:
     • "Nucleotides and DNA" at Biology LibreTexts.

4. Base Pairing Concept

   • Description: A visual representation of base pairing in DNA, illustrating the specific pairing between adenine-thymine (A-T) and guanine-cytosine (G-C).
   • Image Source:
     • "DNA structure" on Wikimedia Commons.
     • "Base pairing and DNA replication" at Khan Academy.

5. Genes and Alleles

   • Description: An educational chart displaying the concept of genes, alleles, and loci on a chromosome linked to genetic traits.
   • Image Source:
     • "Genes and Chromosomes" at Learn Genetics.
     • Find resources on Genetics Home Reference.

6. Chromosome Replication

   • Description: An illustration depicting the process of chromosome replication during cell division (specifically during the S phase of the cell cycle).
   • Image Source:
     • "DNA Replication" at Nature Education.
     • Also available at ScienceDirect.

Note on Citing Images

When you include images in your digital gallery, make sure to properly cite each according to the format you are using (APA, MLA, etc.). A typical citation might include:

• Author (if known). (Year). Title of the work. Source or Website. URL

Example Citation

For a DNA structure diagram from Wikimedia Commons:

• Kadyk, L. (2015). DNA Structure. Wikimedia Commons. https://commons.wikimedia.org/wiki/File:DNA_Structure.svg

Final Instructions

To create your digital gallery:

1. Gather the images as proposed and save them onto your digital platform (Google Slides, PowerPoint, or a website).
2. Ensure each image is labeled appropriately and includes the citations.
3. Add any additional context or explanations as needed to help elucidate each section of the gallery.

This collection will serve as a valuable resource for understanding the structure, function, and significance of DNA in biology!
