The building blocks of DNA - on paper

Mon, 9 Mar 2009 17:41:02 -0700

This learning activity is designed to help students use molecular structure images without the molecular-viewing software. Students work with images from Cn3D on paper (or on screen as a pdf document) to identify nucleotides, base pairs, parts of nucleotides. If you’re an instructor, you can also use the image page as a quiz. If you’re a student, this is a great way to learn about the four bases in DNA and review their structure.

This package includes the following items:
1). Instructions
2). Worksheets - Only a few pages are shown here.
3). A page with nucleotide images.
4). An answer key

This package is only $3.99. Download it now!

The building blocks of DNA

Sun, 1 Mar 2009 11:14:05 -0800

This learning activity is designed to help students explore the structure of the nucleotides in DNA. Students work with annotated molecular structures of guanine, cytosine, adenine, and thymine to identify the parts of the nucleotide and learn about the four different bases in DNA.

This package includes the following items:
1). Molecular structure files containing guanine and cytosine, adenine and thymine, and double-stranded DNA.
2). Instructions
3). Worksheets - these can also be used without the molecular models or software.
4). An answer key
5). User-friendly molecular modeling software (Cn3D 4.1).

At only $3.99, the worksheets alone are a bargain. Download the package and get started today! We have versions for both Mac OSX and Windows XP or Vista.

A Beginner’s Guide to Molecular Structures

Mon, 26 Jan 2009 18:05:35 -0800

Why learn from drawings in a book when you can learn from the structures themselves? Over 40,000 structures of DNA, RNA, and proteins are stored in public databases. Using free software from the National Library of Medicine, you see DNA and proteins come to life in three-dimensions! Written for a general audience, A Beginner's Guide to Molecular Structures is designed to help anyone learn how to find and manipulate molecular structures using the free-viewing program, Cn3D. Working with structures is fun, Cn3D is easy to use, and it works on both Windows and Mac OS X.
