Primary Distinction – Anaphase 1 vs 2

Anaphase 1 and anaphase 2 are two phases within the meiotic division of cells which produces gametes throughout the sexual copy. Meiosis is split into two main phases referred to as meiosis 1 and meiosis 2. Meiosis 1 is adopted by meiosis 2. Anaphase 1 is a sub part in meiosis 1 and anaphase 2 is a sub part of meiosis 2. Throughout meiotic division, haploid gametes are produced from diploid germ cells. The primary distinction between anaphase 1 and a couple of is that homologous chromosomes are separated throughout anaphase 1 whereas sister chromatids are separated throughout anaphase 2.

What’s Anaphase 1

Anaphase 1, which takes place on the meiosis 1, is the part the place homologous chromosomes are separated step. The metaphase 1 is adopted by the anaphase 1. Throughout metaphase 1, homologous chromosome pairs are organized within the metaphase plate and each centromeres are hooked up to a single kinetochore microtubule. The spindle microtubules are contracted, leading to a steady counterbalancing forces on the homologous chromosome pairs. The cohesin protein complexes which bind the 2 homologous chromosomes collectively are damaged down, separating the 2 chromosomes from the homologue because of the pressure generated by the kinetochore microtubules. After the correct bi-orientation of chromosomes, the cell is able to continuing into anaphase 1.

Throughout anaphase 1, homologous chromosomes are pulled in the direction of the other poles by the shortening of kinetochore microtubules. The non-kinetochore microtubules are lengthened as a way to push the chromosomes additional aside. Homologous chromosomes are separated from the cohesin on the arms of the chromosomes. Every separated bivalent chromosome begins transferring in the direction of the other poles because of the stress generated by the microtubules. Anaphase 1 is adopted by telophase 1 the place the bivalent chromosomes arrive on the reverse poles. The primary division of the cytoplasm is initiated on the anaphase 1.

What’s Anaphase 2

Anaphase 2, which takes place on the meiosis 2, is the step the place sister chromatids are separated. Metaphase 2 is adopted by anaphase 2. Throughout metaphase 2, two kinetochore microtubules, every from two reverse poles, are hooked up to the identical centromere of the person chromosomes. These bivalent particular person chromosomes are aligned at a brand new equatorial metaphase plate which is rotated by 90º relative to the anaphase 1. The right association of the person chromosomes on the equatorial plate, binding with the kinetochore microtubules lets the cell to proceeds into the anaphase 2. Throughout anaphase 2, the centromeric cohesion protein complexes are cleaved because of the contacting stress of the kinetochore microtubules on the centromere of the every particular person chromosome. Thus, the bivalent chromosomes are separated into two sister chromatids. Every sister chromatid is now referred to as a daughter chromosome. Additional contraction of the kinetochore microtubules pulls every daughter chromosome in the direction of the other poles. Anaphase 2 is adopted by the telophase 2 the place the formation of the haploid nuclei on the reverse poles is taken place.

Anaphase 2: Anaphase 2 takes place throughout meiosis 2.

Haploid vs Diploid

Anaphase 1: Anaphase 1 happens in diploid cells.

Anaphase 2: Anaphase 2 happens in haploid cells.

Spindle Fibers

Anaphase 1: Two spindle fibers are hooked up to the centromere of the every chromosome within the homologous pair.

Anaphase 2: Two spindle fibers are hooked up to the identical centromere of a single chromosome.

Separation In the course of the Phases

Anaphase 1: Homologous chromosomes are separated throughout anaphase 1.

Anaphase 2: Sister chromatids are separated throughout anaphase 2.

Splitting of the Centromere

Anaphase 1: The centromeres of every chromosome within the homologous pair stay untouched.

Anaphase 2: Two sister chromatids are separated by splitting the centromere.

Anaphase

Anaphase 1: Anaphase 1 is just not just like the anaphase of the mitosis.

Anaphase 2: Anaphase 2 is just like the anaphase of the mitosis.

Aircraft

Anaphase 1: Throughout anaphase 1, homologous chromosomes are organized within the cell equator.

Anaphase 2: Throughout anaphase 2, particular person chromosomes are organized in a airplane which is rotated by 90º relative to the anaphase 1.

Separation of the Cohesin Protein Advanced

Anaphase 1: The cohesin proteins on the chromosomal arms are cleaved throughout the anaphase 1.

Anaphase 2: The cohesin protein complexes on the centromere are cleaved throughout the anaphase 2.

Finish Outcome

Anaphase 1: Chromosomes are current on the opposing poles on the finish of the anaphase 1.

Anaphase 2: Sister chromatids are current on the opposing poles on the finish of the anaphase 2.

Conclusion

Anaphase 1 and a couple of are two phases that happen in meiosis 1 and meiosis 2 phases respectively. Anaphase 1 takes place in 4n cells whereas anaphase 2 takes place in 2n cells. Anaphase 1 produces a 2n cell from the 4n cell. Anaphase 2 produces an n cell from a 2n cell. Throughout anaphase 1, a single kinetochore-microtubule is hooked up to every of the chromosomes within the homologous chromosome pair. Throughout anaphase 2, two kinetochore microtubules, every from one pole of the 2 reverse poles, connect to the identical centromere of the bivalent chromosome. Contraction of the kinetochore microtubules lets the separation of both homologous chromosome pair or the person chromosome into chromosomes and sister chromatids respectively. Subsequently, the principle distinction between anaphase 1 and a couple of is their separations on the equatorial plate.
