DNA: The Code of Life

Explore the fascinating world of DNA, the blueprint of life, and discover why some lobsters are blue! This engaging video explains how DNA encodes unique genetic information that determines traits in organisms, from hair color to dietary capabilities. Learn about the structure of DNA, its replication process, and the vital roles of messenger RNA (mRNA) and transfer RNA (tRNA) in protein synthesis. Join our fun marshmallow lab activity to visually create a DNA model. Uncover the connections between genetics and the vibrant colors in nature!

  1. DNA: The Code of Life

  2. Why are lobsters blue?https://www.youtube.com/watch?v=e2n1cwAXbaY

  3. DNA • Because there are so many possible combinations of bases and genes, each individual organism has a unique set of DNA. • DNA can be found in all of the cells of your body except for red blood cells!

  4. DNA contains the genetic information for cells to make proteins. Proteins determine a variety of traits, from hair color to an organism’s ability to digest food.

  5. It took almost 100 years after the discovery of DNA for scientists to figure out that it looks like a twisted ladder.r.

  9. Part 2 marshmallow labReplication • DNA REPLICATION – •     occurs in the nucleus of a cell.    is the process in which and identical copy of a DNA STRAND IS FORMED FOR A NEW CELL  • It ensures that each daughter cell will have all of the genetic information it needs to carry out its activities.

  10. RNA is different from DNA

  11. There are two kinds of RNA • 1.MESSENGER ribonucleic acid             (mRNA)-             copies the coded message from the DNA in the nucleus            mRNA will copy adenine with uracil instead of thymine            mRNA carries the transcription message off the DNA into the cytoplasm,         mRNA attaches to a ribosome •  2.TRANSFER RNA        (tRNA)-         carries amino acids coded for with three nucleotides        the amino acids then are add to the growing protein.
