Chromosomes 101 ๐ŸŒˆ

  • Origin: Greek (chroma = colour, soma = body) - because they stain well with certain dyes.
  • Every human cell with a nucleus contains these thread-like structures.
  • Think of a chromosome as a "package" filled with coiled up DNA.

๐ŸŽˆFun Fact: DNA looks like a twisted ladder called a double helix! Imagine climbing up that in your favorite sneakers.

DNA bature's barcode ๐Ÿ›๏ธ

  • It's a super long code made up of chemical bases:
    • A = Adenine
    • G = Guanine
    • C = Cytosine
    • T = Thymine
  • These bases pair up, like the best dance partners ever.
  • The base pairs are like the steps on our ladder (the double helix).

๐Ÿ” Food for Thought: If DNA was a book, it'd have about 3 billion letters! That's one thick novel.

Chromosomes the chapters of our book ๐Ÿ“š

  • Our 3 billion base "book" is divided into 23 "chapters" or chromosomes.
  • Each chromosome is there twice (except for special ones in sex cells).
  • We've got 23 pairs, one from mom and one from dad.
  • Both code for the same features (like your cute nose or your epic ability to dance) but might be a tad different.
