DNA and RNA - Part 1

There are six boxes on this genetics worksheet. In one, learners draw and label the DNA molecule. In another, they compare pre-mRNA to mRNA. Other boxes require definitions, labeling, and explaining relationships. 

Five percent of the weight of a human cell comes from RNA, while only one percent comes from DNA. The video explains what RNA is and how it relates to DNA. It also describes the importance of understanding RNA and the two types of RNA:...

Every single cell in the human body is packed with genetic material! A video presentation provides a thorough overview of the components of this genetic material. An engaging instructor defines DNA and RNA and discusses its structure and...

 Explain the differences between DNA and RNA with a short video that includes information about the uracil versus thymine contrast and includes details about structural, functional, and bond discrepancies.

Viewers explore the structures of RNA and DNA and then learn how DNA replicates itself. The narrator explains the central dogma, showing how DNA is eventually translated into proteins, before briefly discussing genetic engineering. 

Messenger RNA, transfer RNA, and ribozymes ... the many faces of RNA. The structure of RNA makes it much more versatile than the very similar DNA. Learners view a slideshow presentation to learn all about the different forms and...

Don't leave genetics to the imagination! Demonstrate to your class the folding of RNA using a video animation. The animation shows the structure of RNA and how it folds on itself to create protein-like structures.

For years, scientists believed tRNA was junk left over from larger RNA. Three scientists used different approaches to prove tRNA actually exists as the connection between DNA and protein. Learn about their experiments, their lives, and...

Genetic information transfers through nucleic acids, making these the chemical link that connects people to their parents and grandparents. Viewers determine the importance of both DNA and RNA after observing the presentation. Key...

[Free Registration/Login may be required to access all resource tools.] An overview of RNA, its three main types and their functions are discussed in this tutorial. After completing this activity, students will be able to compare DNA to...
