Answer:
Explanation:
1.A deletion mutation occurs when a wrinkle forms on the DNA template strand and subsequently causes a nucleotide to be omitted from the replicated strand.
2.This type of variant results in a shortened protein that may function improperly, be nonfunctional, or get broken down. An insertion changes the DNA sequence by adding one or more nucleotides to the gene.
3. A substitution mutation can cause the following: Change in the coding of amino acids codon to a particular stop codon resulting in an incomplete protein, which is usually non-functional. Can cause Silent mutations where a codon change can encode the same amino acid resulting in no changes in the protein synthesized.
4. when a premature nonsense or stop codon is introduced in the DNA sequence. When the mutated sequence is translated into a protein, the resulting protein is incomplete and shorter than normal. Consequently, most nonsense mutations result in nonfunctional proteins.
The answer is true because the ozone layer traps radiation which is heat and distributes it evenly across earth
Answer:
Microglial cell
Explanation:
The microglial cells are macrophages that are in the central nervous system (brain and spinal cord) protecting it. This cells will phagocytize damaged neurons as when a person has Alzheimer as well as agents that can cause a potential damage to the central nervous system such as the meningitis virus. When the Microglial cells phagocytize they absorb the damaged neuron or antigen and then they destroy it.
