Biochemistry is the branch of science concerned with the chemical and physical-chemical processes that occur with living organisms<span />
Answer: The change in the structure of the genes or change in the DNA sequence is called mutation. The mutations are of different types that are deletion, rearrangement, insertion and others.
Explanation:
Mutation in which the one to several nucleotides get changed at a point is called point mutation. The point mutation can be in the form of deletion, substitution, and insertion. Deletion will involve the removal of nucleotide that involves the change in the sequence of DNA. When the nucleotide is added to the genome it is called insertion. In deletion and insertion the whole sequence of nucleotides from the point of mutation get displaced this affect the codons in the amino acid sequence which is responsible for protein synthesis so the functioning of the body may get affected by such mutations.
In the case of substitution the new nucleotides are added to the DNA sequence and the one which was already present at that place is removed. So, only one amino acid in the sequence will change so the polypeptide structure will not be affected.
Answer:
Gregor Mendel
How traits are passed from one generation to the next-and sometimes skip generations-was first explained by Gregor Mendel. By experimenting with pea plant breeding, Mendel developed three principles of inheritance that described the transmission of genetic traits, before anyone knew genes existed.
Explanation:
.
The correct answer is "delirium tremens"
<span>
In the event of abrupt cessation of alcohol use,
there will be an adaptive response of the central nervous system leading to
overactivity which explains the withdrawal symptoms. In the event of central
nervous system hyperactivity, mild symptoms include but not limited to
insomnia, tremors, mild anxiety, headache, and diaphoresis; these symptoms
appear usually within six hours of cessation. Withdrawal-related seizures
characterized as generalized tonic-clonic convulsions as well as alcoholic
hallucinosis or hallucinations related to abrupt alcohol cessation may occur in
moderately severe cases. In most severe cases, delirium tremens may occur and
this is characterized by hallucinations, disorientation, tachycardia, and
agitation. </span>
