A synthetic 20 amino acid polypeptide named Betanova was designed as a small soluble molecule that would theoretically form stab
ra1l [238]

Answer:

The β-Turns in this sequence are two and include the Glycine (G), the two anterior amino acids, and the one posterior amino acid.

You will find the molecule image in the attached file.

Explanation:

β-Turns are structural elements that intervene in the orientation of the polypeptide backbone. These are short sequences of amino acids, with a characteristic conformation, that imposes a sharp 180º turn on the polypeptide chain. They are very abundant in globular proteins, such as Betanova, connecting the two adjacent antiparallel segments of the sheet.    

They are mostly composed of four amino acids. In most cases, the third amino acid is usually Glycine, and in other cases, the second amino acid is Proline. In any case, the first residue of the sequence forms a hydrogen bridge with the last residue of the sequence, linking the amide-group of the last amino acid with the carbonyl-group of the first amino acid in the sequence.    

According to the given sequence of the protein, we can find two specific regions in the molecule that contains glycine (G). Proline is not present in Betanova. Following the theory, in most turns, Gly seems to be the third amino acid of the short sequence. So, we can assume that the first two amino acids that are located before the G and the amino acid located after the G, are the ones that compose the β-Turns.

  • The first turn (QNGK) turns the direction of the polypeptide 180º, going forward to the opposite side.
  • The second turn (NNGK) turns again the direction of the polypeptide, driving the last strain to the other side.          

In the attached image, you will find the structure of Betanova showing strands (black arrows) and turns (red arrows).

Which of the following tissues, cells, or structures in flowering plants is a part of the sporophyte generation and therefore di
jeka94

Answer:

Cell of and integument

Explanation:

When flowering plants reproduce by sexual reproduction, they form seeds contained into fruits. The fruit is derived from the maturation of the flower's ovary (female part) after fertilization.

A mature seed contains three generations:

  1. a diploid embryo (the new sporophyte),
  2. The embryo is surrounded by haploid female gametophyte tissue that supplies nutrition
  3. All the above structure is in turn surrounded by the seed coat (diploid parental sporophyte tissue). The seed coat is produced by integument cells to protect the embryo during its development and before its can germinate. As it is produce by it parental plant, its ploidy level diploid.

In contrast, the generative nucleus and sperm cell are part of male gametophyte (pollen grain) and therefore haploids. Synergid cell is part of embryo sac, therefore belongs to female gametophyte and thus being haploid. Finally, cell of endosperm is usually derived from the fusion between a sperm cell and one of the two female gametes present within the embryo sac, thus being triploid.
