Season 1: DNA and Chromosomes Episode 5: Chromosome Structure Series: Genetics Season 1: DNA and Chromosomes Episode 5: Chromosome Structure Objective: Create a model to show the relationship between DNA and Chromosomes Bell Ringer: Get out your notebook and prepare for notes! Gwahaha!
Structure of Chromosomes
DNA
DNA DNA is the genetic material that codes for you
DNA DNA is the genetic material that codes for you A section of DNA codes for a gene
DNA must be loose during interphase in order to be read
Chromosomes
Chromosomes Chromosomes are made of DNA and histones (proteins)
Chromosomes Chromosomes are made of DNA and histones (proteins) The DNA wrapped around the histones is called chromatin
The chromatin then condenses to create a chromatid
The chromatin then condenses to create a chromatid A duplicated chromosome is made of two chromatids held together by a centromere
DNA condenses into chromosomes during mitosis and meiosis
DNA condenses into chromosomes during mitosis and meiosis The condensed package allows the DNA to be evenly divided between the new cells.
