Answer:

Different antibiotics work differently from each other, some attack bacterial cell wall, some attack proteins, some attack ribosomes and some attack DNA replication machinery.

Antibiotics that attack the ribosomes such as 'tetracycline' actualy inhibit the bacteria to grow by attacking their protein synthesis. Protein synthesis is accomplished in ribosomes, tetracycline cross the bacterial membrane and enter cytoplasm from there i binds on a single specific site on the ribosomes which result in the halting of RNA interaction that stops protein synthesis or extension. In humans, the accumulation of such antibiotics is not to such an extent that it damages the cell machinery.

15. A science student claims that a substitution mutation is less likely to affect gene function than an insertion or deletion m
Nat2105 [25]

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.

A calico cat has both black and orange spots, which demonstrates a codominance pattern. What would be their expected genotype?
Oksi-84 [34.3K]

Answer:

Calico is a coat color found in cats, which is caused by a SEX-LINKED, CODOMINANT allele.

Explanation:

Codominance means that neither allele can mask the expression of the other allele. An example in humans would be the ABO blood group, where alleles A and alleles B are both expressed. So if an individual inherits allele A from their mother and allele B from their father, they have blood type AB.
