Your question: In which sub phase of meiosis chromosome is found clearly visible?

Chromosomes condense further during the diakinesis stage, from Greek words meaning “moving through”. This is the first point in meiosis where the four parts of the tetrads are actually visible. Sites of crossing over entangle together, effectively overlapping, making chiasmata clearly visible.

In which phase of meiosis chromosomes are clearly visible?

Complete step by step answer:

In pachytene, the bivalent chromosomes clearly appear as a tetrad. While these chromosomes were formed in the zygotene stage of the prophase- I by the process of association of synaptonemal complexes called synapsis.

In which phase chromosomes are most visible?

Metaphase is a stage in the cell cycle where all the genetic material is condensing into chromosomes. These chromosomes then become visible.

During which phase chromatids are clearly seen?

The first two stages of prophase I are relatively short-lived compared to the next stage that is pachytene. During this stage, the four chromatids of each bivalent chromosomes becomes distinct and clearly appears as tetrads.

Who gave the term meiosis?

The term meiosis, derived from the Greek word for “lessening” was coined in 1905 by Farmer and Moore to reflect the halving of the chromosomes.

Which phase comes between G1 and G2?

Complete answer:

Sl.No S phase
1. S phase or synthesis phase is the second sub-phase of interphase.
2. It occurs in between the G1 (Gap 1) phase and G2 (Gap 2) phase.
3. It is the phase of the cell cycle in which DNA replication takes place.

What three phases are individual chromosomes no longer visible?

It is during interphase, telophase, and cytokinesis that the chromosomes are no longer visible.

Are chromosomes visible?

Chromosomes are not visible in the cell’s nucleus—not even under a microscope—when the cell is not dividing. However, the DNA that makes up chromosomes becomes more tightly packed during cell division and is then visible under a microscope.

What is S phase in cell cycle?

S phase is the period of wholesale DNA synthesis during which the cell replicates its genetic content; a normal diploid somatic cell with a 2N complement of DNA at the beginning of S phase acquires a 4N complement of DNA at its end.
