In which of the following stage the chromosome is thin and like long thread?

Leptotene is a stage in the prophase 1 of meiosis. In this stage chromosome appears thin and long.

In which stage the chromosome a thin and long thread like?

The leptotene stage, also known as the leptonema, is the first of five substages of prophase I in meiosis. The term leptonema derives from Greek words meaning “thin threads”. A cell destined to become a gamete enters the leptotene stage after its chromosomes are duplicated during interphase.

In which stage do chromosomes become visible as fine long threads?

Prophase. (c) Chromosomes become visible as fine long threads.

In which phase condensation of basically thin thread like chromosomes starts?

Answer: Leptotene- It is the beginning of the prophase and the chromosomes appear as thin long threads.

When chromosomes are thin they are called?

At the leptotene stage the chromosomes appear as long, thin threads. At pachytene they pair, the corresponding portions of the two chromosomes lying side by side. The chromosomes then duplicate and contract into paired chromatids.

What stage do chromosomes appear?

Metaphase is a stage in the cell cycle where all the genetic material is condensing into chromosomes. These chromosomes then become visible. During this stage, the nucleus disappears and the chromosomes appear in the cytoplasm of the cell.

THIS IS INTERESTING:  What would happen if there is no meiosis?

Are thin thread-like structures that condense and form short thick chromosomes?

Answer: During prophase, the nuclear chromatin condenses into short and thick chromosomes. It appears like a rounded structure inside the nucleus. During metaphase, the chromatin material condenses completely and chromosomes appear most distinct.

What is Zygotene stage?

The zygotene is the stage of prophase I that follows after leptotene and precedes pachytene. … Zygotene is that phase wherein the homologous chromosomes pair or come together in synapse. The pairing or coming together of homologous chromosomes is called synapsis. It may be facilitated by the synaptonemal complex.

How many chromosomes are in a parent cell in meiosis?

By the end of meiosis, the resulting reproductive cells, or gametes, each have 23 genetically unique chromosomes. The overall process of meiosis produces four daughter cells from one single parent cell. Each daughter cell is haploid, because it has half the number of chromosomes as the original parent cell.
