Genes are segments of DNA located on chromosomes. A gene mutation is defined as an alteration in the sequence of nucleotides in DNA. This change can affect a single nucleotide pair or larger gene segments of a chromosome. DNA consists of a polymer of nucleotides joined together. During protein synthesis, DNA is transcribed into RNA and then translated to produce proteins. Altering nucleotide sequences most often results in nonfunctioning proteins. Mutations cause changes in the genetic code that lead to genetic variation and the potential to develop the disease. Gene mutations can be generally categorized into two types: point mutations and base-pair insertions or deletions.
Answer:
Newton's law's
Explanation:
Basically anything that has been proven to always be true
1.Every object in a state of uniform motion will remain in that state of motion unless an external force acts on it.
2.Force equals mass times acceleration
3.For every action there is an equal and opposite reaction.
Answer:
Neurotransmitters
Explanation:
Neurotransmitters are the chemicals present in the body used for the propagation of action potential. These neurotransmitters are also known as the body chemical messengers.
Neurotransmitters are stored in the neural cells. These chemicals are generally released when the cell is stimulated by the specific signal. The effect of neurotransmitter may be excitatory or inhibitory.
Thus, the answer is option (4).
It accuses in warm or wet climates. Rocks break down by dissolving or reacting with the minerals that are in the rock.
