Answer:
(B) semiconservative.
Explanation:
According to the model proposed by Watson and Crick, the DNA molecule consists of two polynucleotide chains arranged on a helix around an imaginary axis, rotating to the right (a double helix). That is, the DNA molecule is in the shape of a spiral staircase, in which the "steps" are made up of nucleotide nitrogen bases and the "handrails" are covalently linked phosphate and sugar - so it is said that DNA is shaped like a helical ribbon. Also according to Watson and Crick DNA replication is semi-conservative, because each strand of DNA will give rise to another strand that will be complementary to its nucleotides.

4. One risk factor is it could spread and potentially turn into a different form of cancer.
5. You can prevent it by using sunscreen, routine skin checks, covering skin with clothing and avoiding the sun.
Answer:
Recombinant DNA can replace a gene in an animal’s genome.
Explanation:
The molecular cloning process involves in creating Recombinant DNA. This DNA is used to replace or replicate any specific gene. This is done by the process of PCR to replicate it directly.
This formation is done in the presence of a vector. This method is used in the field of veterinary office, pharmacy and many more. It has the ability to replace the gene of an animal’s genome.
Answer:
In biology, a mutation is an alteration in the nucleotide sequence of the genome of an organism, virus, or extrachromosomal DNA. Viral genomes contain either DNA or RNA.
