Asexual Reproduction- involves a single parent producing the offspring
Sexual Reproduction- offspring are produced by the fusion of two sex cells (one from each of two parents)
Chromosomes- single, circular DNA molecules that contains most of the cell's genetic information
Chromatin-substance found in eukaryotic chromosomes; composed of DNA and histone proteins
Binary Fission- a form of asexual reproduction during which two genetically identical cells are produced
Chromatid- each strand of a duplicated chromosome
Centromere- the area where each pair of chromatids is joined
Centrioles- tiny structures located in the cytoplasm of animal cells that help organize the spindle
Spindle- a fanlike microtubule structure that helps separate the chromatids ]]> 2021-05-12 13:11:33 UTC https://padlet.com/2024daviese/aobiteys2zc96xlb/wish/1517305298 2024daviese https://padlet.com/2024daviese/aobiteys2zc96xlb/wish/1517369417 Four Phases-
Prophase
step 1- duplicated chromosome condenses and becomes visible
step 2- the centrioles move to opposite sides of the nucleus and help organize the spindle
step 3- the spindle forms and DNA strands attach at their centromere
step 4- the nucleolus disappears and nuclear envelope breaks down
Metaphase
step 1- centromeres of the duplicated chromosomes line up across the center of the cell
step 2- the spindle fibers connect to the centromere of each chromosome to the two pieces of the spindle
Anaphase
step 1- the centromeres are pulled apart and the chromatids separate to become individual chromosomes
step 2- the chromosomes separate into two groups near the poles of the spindle
Telophase
step 1- the chromosomes spread out into a tangle of chromatin
step 2- nuclear envelope re-forms around each cluster of chromosomes
step 3- the spindle breaks apart
step 4- a nucleolus becomes visible in each daughter nucleus ]]> 2021-05-12 13:26:05 UTC https://padlet.com/2024daviese/aobiteys2zc96xlb/wish/1517369417 2024daviese https://padlet.com/2024daviese/aobiteys2zc96xlb/wish/1519576414 https://youtu.be/f-ldPgEfAHI]]> 2021-05-13 00:25:00 UTC https://padlet.com/2024daviese/aobiteys2zc96xlb/wish/1519576414 2024daviese https://padlet.com/2024daviese/aobiteys2zc96xlb/wish/1519607512 Aexual reproduction has advantages such as: being quick and easy, and many offsprings can be created.
Sexual reproduction can also have many advantages such as: genetic diversity and offspring can adapt to changes.]]> 2021-05-13 00:37:05 UTC https://padlet.com/2024daviese/aobiteys2zc96xlb/wish/1519607512 2024daviese https://padlet.com/2024daviese/aobiteys2zc96xlb/wish/1519611669 (step 1)]]> 2021-05-13 00:38:39 UTC https://padlet.com/2024daviese/aobiteys2zc96xlb/wish/1519611669 2024daviese https://padlet.com/2024daviese/aobiteys2zc96xlb/wish/1519612395 (step 3)]]> 2021-05-13 00:38:55 UTC https://padlet.com/2024daviese/aobiteys2zc96xlb/wish/1519612395 2024daviese https://padlet.com/2024daviese/aobiteys2zc96xlb/wish/1519614504 (step 2)]]> 2021-05-13 00:39:40 UTC https://padlet.com/2024daviese/aobiteys2zc96xlb/wish/1519614504 2024daviese https://padlet.com/2024daviese/aobiteys2zc96xlb/wish/1519622524 (step 4)]]> 2021-05-13 00:42:34 UTC https://padlet.com/2024daviese/aobiteys2zc96xlb/wish/1519622524 2024daviese https://padlet.com/2024daviese/aobiteys2zc96xlb/wish/1519627791 1.  Define Prophase - The spindle forms and DNA strands attach at their centromere
