Three steps are needed to extract DNA from learners' inner cheek cells. The procedure and reasons for each step are explained. As enzymes work on the cells, a series of questions are answered regarding the structure of the DNA molecule....

How do cells know when to replicate, transcribe, and stop? James E. Darnell, Jr. shifted from studying medicine to biochemistry and decided to address this mystery. Learn about his research, discoveries, and the impact on future medical...

Watson and Crick built the first model of DNA in the 1950s, and our understanding of DNA since then continues to grow exponentially. Scholars learn about protein synthesis by observing a presentation and completing a worksheet. Both walk...

In this DNA replication worksheet, students review the steps that take place for DNA replication. This worksheet has 9 fill in the blank questions.

For this DNA: structure and replication worksheet, students fill in the blanks about the structure of DNA and replication of DNA. Students sketch several diagrams of DNA at different stages.

How well do your pupils understand DNA, mRNA, and amino acids? This three-page handout will help you assess their comprehension through sequencing questions, fill in the blanks, and labeling diagrams.

A comprehensive five-page quiz or study guide covering DNA and its related processes. Young geneticists will need a strong understanding in order to complete this handout, which includes multiple choice, matching, compare/contrast, and...

In this protein synthesis worksheet, learners use a given strand of DNA to write the complimentary base pairs. They transcribe the message to the RNA and then they translate the message into the proper amino acids using the codons on the...

For this RNA and gene expression worksheet, students match the letter of the description that best matches the term as it relates to gene expression. Students also answer questions as it relates to the process of transcription and...

Start seeing double. The American Museum of Natural History website provides pupils with information about Dolly, the cloned sheep. Learners find out the procedure used to create Dolly along with why scientists clone animals.

Compare and contrast eukaryotes, prokaryotes, and viruses with a chart and a Venn diagram. Beginning microbiologists consider motility, reproductive ability, DNA content, and the presence of organelles. They write short answers to...

In this cell division activity, students review the steps involved in a human somatic cell, from interphase to mitosis, to cytokinesis. This activity has 21 fill in the blank statements.

For this biology worksheet, students label 9 diagrams with the correct names. They also write short answers to 6 questions that follow.

This site explains the nucleus, the control center of a cell, and DNA replication.

[Free Registration/Login may be required to access all resource tools.] During mitosis, the DNA in a nucleus must replicate. The copied DNA is divided into two genetically identical sets, so that after cytokinesis or cell division, each...
