Answer:
linker DNA
Explanation:
the classic beads on a string structure is termed as the nucleosome; which is the most basic level of chromosome packaging. the nucleosome is made up of 2 molecules each of the four histone proteins (H2A, H2B, H3, H4) to form an octamer around which a length of DNA is wrapped. linkage of this nucleosome to another nucleosome is done by a length of linker DNA and a linker histone (H1). thus experimentally to produce this structure, the linker DNA between two nucleosomes is degraded by nucleases to extract the structure. thus the linker DNA is not retained after the experiment.
Eukaryotic cells contain membrane-bound organelles, such as the nucleus, while prokaryotic cells do not. Differences in cellular structure of prokaryotes and eukaryotes include the presence of mitochondria and chloroplasts, the cell wall, and the structure of chromosomal DNA.

Answer:
4 amino acids.
Explanation:
To become translated into protein, a sequence is read in triplets called codons.
Each codon that codes for an amino acid is made up of 3 nucleotides.
Therefore, a sequence of 15 nucleotides would be translated into a polypeptide that is made up of 5 amino acids. (15 divided by 3 = 5)
However, we are told that there is a stop codon at the end of this sequence.
A stop codon is a specialised codon that does not code for an amino acid, but tells the protein machinery that the polypeptide is complete.
Therefore, the polypeptide would have 5-1 amino acids, which corresponds to 4 amino acids.
