tetrads form during synapsis

taurus [48]3 years ago
3 0

Answer:

tetrads form

Explanation:

In meiosis, during Profase I the chromosome pairs become visible with long thin filaments. As in mitosis, they were already duplicated during the preceding interphase, thus consisting of two chromatids joined by the centromere. However, at this stage, the degree of condensation is such that they look like single structures.

The homologous chromosomes pair very precisely, which starts at various points and then progresses like a zipper that closes, forming what is called tetrads. This pairing (which is the synapse) is critical for meiosis to occur, so this phenomenon cannot occur in haploid cells.

HELP I NEED A SCIENTIFIC MODEL AND PARAGHRAPH ABOUT ATOMIC THEROY WILL GIVE BRANLIEST AND POINTS
saveliy_v [14]

<h2>Atomic Theory:</h2><h2>Introduction</h2>

The atomic theory of Atoms Summed up is the idea that all matter is made of tiny particles that are imperceptible to the mortal eye; these particles are named Atoms

<h2>Paragraph 1:</h2>

John Dalton was the first to consider that all matter was made of tiny particles known as atoms. He invented the idea that matter is formed of atoms varying in weight.

<h2>Paragraph 2:</h2>

I created this model of the dissimilarities between three kinds of matter-- solids, liquids, and gases. The distance between atoms in each state tells us what type of matter we observe.

The Drawing is on the file

Which three statements correctly describe the endoplasmic reticulum?
Sunny_sXe [5.5K]

I have searched everywhere, but I have not found the proposals of the question, but I will explain to you what is the endoplasmic reticulum so that you can answer it.

The endoplasmic reticulum is a eukaryotic organelle located in the cytoplasm.

The endoplasmic reticulum is a network of membrane tubules (often interconnected) scattered throughout the cytoplasm of eukaryotic cells. Its membrane, which alone represents more than half of the cellular membrane system, is in contact with the nuclear envelope.

The endoplasmic reticulum can be:

Granular (or rough) (RER) that is to say associated with ribosomes.

Smooth (SER).

The granular endoplasmic reticulum is the place of synthesis (in the associated ribosomes) of the proteins secreted outside the cell and of the proteins and lipids constituting the membranes of the cellular organelles. Golgi, lysosomes, mitochondria, nucleus, ribosomes, vesicles ...). It participates in the correct folding of the proteins that have just been synthesized.

The smooth endoplasmic reticulum participates in cellular metabolism, synthesizing lipids and storing calcium.
