Metaphase is a stage during the process of cell division (mitosis or meiosis). Usually, individual chromosomes cannot be observed in the cell nucleus. However, during metaphase of mitosis or meiosis the chromosomes condense and become distinguishable as they align in the center of the dividing cell.
In which of the following stage the chromosome is single?
Leptotene also known as leptonema is the first stage of prophase I during which individual chromosomes begin to condense into long strands within the nucleus which are loosely interwoven. However, the two sister chromatids are still so tightly bound that they are indistinguishable from one another.
At which stage do chromosomes appear single thin and thread like?
So, the correct answer is ‘Leptotene‘.
Are chromosomes single in anaphase 2?
Anaphase II: Sister chromatids separate to opposite ends of the cell. Telophase II: Newly forming gametes are haploid, and each chromosome now has just one chromatid.
What is the same in all parts of homologous chromosomes?
Homologous chromosomes are similiar but not identical. Each carries the same genes in the same order, but the alleles for each trait may not be the same. … The maternal and paternal chromosomes in a homologous pair have the same genes at the same loci, but possibly different alleles.
What is the correct sequence of cell cycle?
The cell cycle is a four-stage process in which the cell increases in size (gap 1, or G1, stage), copies its DNA (synthesis, or S, stage), prepares to divide (gap 2, or G2, stage), and divides (mitosis, or M, stage). The stages G1, S, and G2 make up interphase, which accounts for the span between cell divisions.
Which is not true for anaphase?
Anaphase – This stage is characterised by events such as, spindle poles moving farther apart, which in turn moves the chromosomes to the opposite poles. … This stands not true for anaphase and hence this is the correct answer.
What does telophase 1 look like?
At each pole, during this stage, there is a complete haploid set of chromosomes (but each chromosome still has two sister chromatids). A cleavage furrow appears, and by the end of this stage the parent cell has divided into two daughter cells. This separation of the cytoplasm is called cytokinesis.
