Budding And Meiosis Flashcards
The second stage of budding
Cell undergoes interphase with DNA and organelles replicating.
The first stage of budding
A bud forms at the surface of the cell
Third stage of budding
The cell undergoes mitosis
Fourth stage of budding
Nuclear division is complete- budding cell contains nucleus that had an identical copy of parent cells DNA
Fifth stage of budding
The bud separates off from the parent cell producing a new, genetically identical yeast cell.
What is the major problem with budding.
New buds cannot for too close to old bud scars, there for this limits the amount of yeast cell being produced.
What are homologous chromosomes?
They are a pair of chromosomes that contain genes for the same characteristics.
What are the three things which occur in meiosis, before the first division?
- DNA replicate and coils up to form chromosomes
- chromosomes arrange themselves into homologous pairs
- Then chromosomes swap genetic information
What occurs in the first division of meiosis?
- homologous pairs split. Any one chromosome can enter either cell.
What occurs in the second division of meiosis?
Chromosomes split.any half can go into either cell. Creating four new genetically different cells.
Why are cell divided my meiosis different from cell who reproduce via mitosis.?
Meiosis cell are genetically different from each other. Due to the swap a genetic information between the chromosomes resulting in each gamete getting a random combination of half of them.
