DerKrebs [107]

Answer:

a network of proteins that holds homologues together.

Explanation:

Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.

The synaptonemal complex is a network of proteins that holds homologues (homologous chromosomes) together.

Generally, a synaptonemal complex (protein lattice) is formed between homologous chromosomes during mitosis and meiosis. Also, synaptonemal complex is important for the formation of the four sister chromatids referred to as tetrads.

Furthermore, the synaptonemal complex (protein lattice) has a tripartite structure which comprises of the following components;

I. SC protein-1 (SYCP1).

II. SC protein-2 (SYCP2).

III. SC protein-3 (SYCP3).

In conclusion, the synaptonemal complex plays a significant role in synapsis, recombination and chromosome pairing.

The interaction between which protein and ion initiates muscle coupling?
labwork [276]

Answer:

Troponin and calcium ions.

Explanation:

Troponin is a component of thin filament along with tropomyosin and actin. It is a protein complex to which calcium binds and start the production of muscular force.

Calcium also playing a very important role in muscle contractions, it binds with troponin and helping to move tropomyosin.

When calcium ion attached to troponin, then conformational changes occurs in troponin shape and moves which allow tropomyosin going away from its inhibitory position from the myosin-binding sites on actin. After this, the energized myosin head starts binding to the actin molecules and starts the cross bridge cycle, which helping in shortening the muscle's fiber.
