If you have never taught a lesson using a Powerpoint presentation, you have to give it a try! My students always prefer this to a traditional lecture.
PLEASE NOTE: I have listed on TpT two different versions of this PowerPoint. This version is slightly longer and is a little more advanced. Please read the description carefully. The shorter version can be found by clicking here: DNA, RNA Powerpoint and Notes - Shorter Version
This powerpoint is on DNA, RNA and Protein Synthesis. It consists of 69 slides that are colorful, informative and visually stimulating. Pictures and diagrams are included that will greatly enhance your instruction to your students. This product also includes a set of notes for the teacher (15 pages) and a set of notes for the student (17 pages). You receive two versions of the notes: A PDF version and a Word document so that you can make changes if needed.
PLEASE NOTE: This PowerPoint is also included in a bundled unit plan containing 20 different products on DNA, RNA, and protein synthesis. You can view the bundled unit plan by clicking here: DNA, RNA, and Protein Synthesis Complete Unit Plan.
Please download my free preview. The preview consists of the first 15 slides of the presentation with the corresponding notes for the teacher and corresponding notes for the student.
Topics covered are:
1) History of DNA Studies: Early concepts about genes, roles played by genes, Watson and Crick, Chargaff, Rosalind Franklin, Maurice Wilkins.
2) DNA nucleotides and their composition, purines, pyrimidines, how nucleotides are joined to one another.
3) The Watson and Crick model of DNA, the double helix, the base pairing rules, DNA as a carrier of information
4) Mechanisms by which a large amount of DNA can fit inside a small space of the nucleus, histones, nucleosomes
5) Replication of DNA: Drawings, steps in replication, DNA polymerase, hydrogen bonds, origins or replication, replication forks, complimentary strands, helicase
6) Proofreading and repairing DNA: the role of polymerases, nucleases, and ligases.
7) The Genetic Code: codons, amino acids
8) RNA: Differences between DNA and RNA, the functions of RNA, the three types of RNA (mRNA, tRNA, rRNA).
9) Transcription: Purpose of transcription, steps to transcription, promoter, terminator, RNA polymerase
10) RNA processing and editing, introns, exons
11) Understanding the genetic code, how codons translate into amino acids, start codons, stop codons, reading a table of codons
12) Translation: protein synthesis, ribosomes, steps in translation, the role of mRNA and the role of tRNA, structure of tRNA and its ability to transport amino acids, reading and deciphering the code.
13) Practice Problem: Given a DNA sequence, students will figure out the corresponding mRNA codon sequence, the tRNA anticodon sequence, and the amino acid sequence.
14) Ribosome structure: large subunit, small subunit, RNA binding sites, the entry and exit of tRNA to build a polypeptide, start codons, stop codons.
15) Mutations: definition of mutation, gene mutations, chromosome mutations, point mutations, base substitutions, base insertions or deletions, silent mutations, frameshift mutations.
16) The importance of mutations in natural selection.
This powerpoint was written with a typical biology I class in mind. It can easily be edited. Middle school teachers may simply want to delete a few of the slides. Honors teachers can easily include a few extra details.
Also included is a set of notes to accompany this powerpoint. It includes a complete set of notes for the teacher, and an outline of the notes for the students. Students will use the outline as the powerpoint is being presented and will fill in the notes as the lesson is being taught.
Also included is a chart of all 64 codons and the amino acids they code for.
