If a person is lacking a gene that codes for a protein involved in nucleotide excision repair, then which of the following statements would be true for that person? Select the answer that is a correct statement. OA They should avoid smoking because their cells will not be able to repair double stranded breaks caused by the alkylating agents found in cigarette smoke. O B. They should avoid radiation because their cells will not be able to perform non-homologous end joining to repair double stranded breaks that ionizing radiation causes. e They should stay out of the sun, because their cells will not be able to repair thymine dimers formed in skin cell DNA caused by UV light. OD They should not smoke because their cells will not be able to perform homologous recombination to repair thymine dimers caused by alkylating agents in cigarette smoke. OE They shouldn't smoke and they should always use sunscreen, but that's because these are simply healthier ways of living that have nothing to do with cells' ability to repair mutations in the genome.

Bacterial Genomics

The study of the morphological, physiological, and evolutionary aspects of the bacterial genome is referred to as bacterial genomics. This subdisciplinary field aids in understanding how genes are assembled into genomes. Further, bacterial or microbial genomics has helped researchers in understanding the pathogenicity of bacteria and other microbes.

Transformation Experiment in Bacteria

In the discovery of genetic material, the experiment conducted by Frederick Griffith on Streptococcus pneumonia proved to be a stepping stone.

Plasmids and Vectors

The DNA molecule that exists in a circular shape and is smaller in size which is capable of its replication is called Plasmids. In other words, it is called extra-chromosomal plasmid DNA. Vectors are the molecule which is capable of carrying genetic material which can be transferred into another cell and further carry out replication and expression. Plasmids can act as vectors.
