The bacterial cell membrane can be targeted for killing it. Inhibition of the synthesis of the components of cell wall will not allow the bacteria to grow.
The genetic material of the bacteria- DNA can be targeted. When DNA is cleaved, or damaged, then the bacteria will die.
The cellular components of the bacteria may be targeted. If a organelle, or a component is responsible for production or transport of proteins, and it is targeted by anti-bacterial compound, then protein synthesis machinery of bacteria will stop working, and it will not be able to perform a number of functions, and eventually die.

Answer:
recessive
Explanation:
A lethal allele is a gene variant associated with a mutation in an essential gene, which has the potential to cause the death of an individual. In general, lethal genes are recessive because these alleles do not cause death in heterozygous individuals, which have one copy of the normal allele and one copy of the allele for the lethal disease/disorder. In recessive lethal diseases, heterozygous individuals are carriers of the recessive lethal allele and can eventually pass the 'defective' allele on to offspring even though they are unaffected; whereas dominant lethal diseases are caused by dominant lethal alleles, which only need to be present in one copy to be fatal. In consequence, the frequency of recessive lethal alleles is generally higher than dominant lethal alleles because they can be masked in carrier individuals. Some examples of human diseases caused by recessive lethal alleles include, among others, Tay-Sachs disease, sickle-cell anemia, and cystic fibrosis.
