RUDIKE [14]3 years ago
4 0
Attached to each sugar is one of four bases--adenine (A), cytosine (C), guanine (G), or thymine (T). The two strands are held together by hydrogen bonds between the bases, with adenine forming a base pair with thymine, and cytosine forming a base pair with guanine.

What structure is most important in forming the tetrads?
Vladimir79 [104]

Answer:

The correct answer will be option- synaptonemal complex.

Explanation:

The tetrad arrangement of the genetic material in an organism is mediated by a highly conserved structure known as the synaptonemal complex.  The synaptonemal complex is formed during the prophase I of the meiosis I which attaches the chromatin of the homologous chromosomes.

The synaptonemal complex is a proteinaceous structure which is formed by the two lateral ladders like elements with a central portion composed of the central element. The chromatin gets attached to the lateral elements while the central a portion bridge space between the two ladders thus help in the formation of the tetrad.

Thus, option- synaptonemal complex is the correct answer.

Compare and contrast the structures of DNA and RNA
katovenus [111]

DNA contains the sugar deoxyribose, while RNA contains the sugar ribose. The only difference between ribose and deoxyribose is that ribose has one more -OH group than deoxyribose, which has -H attached to the second (2') carbon in the ring. DNA is a double-stranded molecule, while RNA is a single-stranded molecule.

During exercise, muscle cells release the protein ________ which can cause brite/beige adipocyte formation:
shepuryov [24]

Answer: Option "D".

Explanation: During exercise muscle cells release irisin protein is being released causing Beige adipocyte formation.

the secretion of Irisin leads to the improvement in muscle activity, bone mineral density, increasing the formation of brown like Beige adipocytes in the tissue.

Adipocytes are divided into two tissues namely white and brown. white tissues generally expand during excessive nutrition and brown adipocytes have mitochondria and burn the energy during exercises resulting into the break down of ATP  molecules increasing the body heat.  

Therefore, during exercise heat generated due to the formation of brown adipocyte tissue which are formed due to the release of irisin protein.
