Learning Objective

Students will explore dna replication through guided practice and application.

Today's Lesson

In this lesson, we'll explore dna replication overview. Scientific inquiry allows us to investigate and explain natural phenomena.

DNA (deoxyribonucleic acid) is the molecule that carries genetic information in all living things. Structure: double helix (twisted ladder), made of nucleotides (A, T, C, G base pairs). Genes are segments of DNA that code for proteins—they're instructions for traits. DNA → genes → proteins → traits. DNA replication lets cells copy genetic information when dividing. DNA is in the nucleus of eukaryotic cells. Understanding DNA explains heredity, evolution, genetic diseases, and biotechnology. It's the blueprint of life!

As you work through today's material, pay attention to the examples and try to identify the patterns or strategies being used. This will help you apply these concepts to new problems.

Take notes on key points and make connections to what you've already learned in previous lessons.
