Centromeres

Please take a look at this statement: Centromeres appear as constitutive heterochromatin in a resting nucleus. Is that true? Does that mean that the centromere sequences have no function in non-dividing cells? So, the centromeres must have sequences ...

... are no longer visible. The spindle apparatus has migrate to opposite poles of the cell.. 3. Metaphase The spindle fibres attach themselves to the centromeres of the chromosomes and align the the chromosomes at the equatorial plate. 4. Anaphase The spindle fibres shorten and the centromere splits, ...

... carrying the maternal a allele segregated with the paternal B allele. In this meiosis, there was no crossing over between genes A or B and their centromeres. The gametes resulting from this meiosis are expected to be? Ok so what i did as seen in the picture is cross two heterozygotes and during ...

... about were microsatellites (dispersed everywhere which are short sequences), dna transposons such as SINES and LINES, alpha satellite repeats in centromeres, telomerase repeats at the end of chromosomes, and some others. I know that sometimes LINES can use reverse transcriptase to insert a mRNA ...

... division of meiosis: Gamete formation Prophase 2: DNA does not replicate. Metaphase 2: Chromosomes align at the equatorial plate. Anaphase 2: Centromeres divide and sister chromatids migrate separately to each pole. Telophase 2: Cell division is complete. Four haploid daughter cells are obtained. ...
