Answer:
"In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure"
Explanation: I just looked it up-
The central nervous system CNS is responsible for integrating sensory information and responding accordingly. It consists of two main components: The spinal cord serves as a conduit for signals between the brain and the rest of the body
Answer:
Nonsense mutation: it causes a premature stop codon, so the protein cannot be fully synthesized.
Missense mutation: it causes change on the aminoacid encoded, so it can cause a change in the protein structure if the new aminoacid doesn't have the same chemichal properties as the original.
Synonymous (silent) mutation: it causes no change, the same aminoacid is encoded.
Single nucleotide insertion or deletion: changes the entire structure of the protein because it shifts the reading frame.
Three nucleotide deletion: one aminoacid will no longer be part of the protein, if this aminoacid was located, for example, on the active site of an enzyme, the protein could lose its function.
Chromosomal translocation: it can break a gene in two, causing the protein to no longer be able to be synthesized, or it can change the transcription regulation because it is now under the effect of other regulating sites that result in a different transcription pattern.
