Storyboard Descripción
A type of nuclear division that results in formation of cells!

- PROPHASE 1
- Oh no the CHROMATIN has CONDENSED! I'm so sad I could BREAKDOWN!
- Chromosome... I think we should be a Homologous Pair
- (Crossing over...)
- Think the cat is wrapping around the dog!
- MEOW!
- WOOF!
- METAPHASE 1
- We're now attached along the equator of spindle!
- -Chromatin condense & chromosome supercoils-Nuclear Envelope breaks down-Chromosomes come together in homologous pairs
- ANAPHASE 1
- Why did the motor protein have to pull us apart...
- -CROSSING OVER occurs when NON-SISTER chromatids WRAP AROUND eachother & may SWAP SECTIONS so ALLELES SHUFFLE
- TELOPHASE 1
- -Homologous chromosomes attach along equator of spindle by centromere (way they line up determines how they'll segregate independently when pulled apart in Anaphase)
- REMEMBER TAMZIN:
- Remember that this is the first stage of Meiosis: MEIOTIC DIVISION!
- -Members of homologous chromosomes pulled apart by motor proteins(cross over areas separate from eachother= swapped areas of chromosome & allele shuffling)
- -EACH NEW NUCLEUS CONTAINS HALF ORIGINAL NUMBER OF CHROMOSOMES!
- Hi, I'm NUCLEUS! I'm the NEW addition to my family. I'm like HALF my mum & HALF my dad
- Remember the definition:HOMOLOGOUS CHROMOSOMES- matching chromosomes containing same genes at same places
