Answer:
The sequence from least damaging to most damaging is silent, missense, frameshift, and nonsense mutation.
Explanation:
A silent mutation refers to a modification in the sequence of nucleotide bases that constitutes DNA, however, it does not result in a substantial change in the amino acid or in the function of the entire protein. In missense mutation, one DNA nucleotide gets switched out with another one in a manner, which modifies the specified amino acid.
When a missense mutation takes place in the molecule of DNA, it changes one of the sequences of RNA codon produced at the time of transcription. A frameshift mutation refers to a specific kind of mutation, which comprise either deletion or insertion of the additional bases of DNA. Following the mutation, the entire sequence of DNA will be read incorrectly.
A nonsense mutation refers to a genetic mutation in the sequence of DNA, which leads to the formation of the shorter or unfinished protein product. This mutation takes place when an undeveloped nonsense or stop codon gets presented in the sequence of DNA.
Thus, the silent mutation is the least damaging as it does not exhibit any influence on the function or composition of the protein. While nonsense mutation shows the most damaging effect as it results in an abrupt termination peptide chain.

Answer:
The correct answer will be-
1. Nucleosomes
2. Chromatin
3. Sister chroamtid
4. Centromere
Explanation:
The DNA is a very long molecule which if has to be passed on to the daughter cell as it is will cause problems. So, to reduce problems a cell form tightly packed structure of DNA so that they can be passed easily to the daughter cell.
The packaging of DNA begins with the wrapping of the DNA around histone proteins which forms the 11 nm basic structural units called nucleosomes. The nucleosomes start condensing each other and form 30 nm structure chromatin fibres.
The chromatin fibres undergo replication during S phase which produces an exact copy of the chromatin called sister chromatids bound to each other at a central point called centromere which helps the separation of the chromatids during M phase.
