"Comparison of conserved sequences among related species usually leads to the identification of sequences, which illustrate the nucleotides most often found at each position of DNA in the conserved region."

Explanation:

Such type of the nucleotide sequence that is mostly present at each position is called a consensus sequence. This sequence plays an important role in the sequence alignment and some other molecular biological research and some other fields. Generally, it is made up of a small segment of the nucleotide and also considered as a conserved sequence motif because its presence is conserved on the position where it is present.

dna damages cause changes in the structure of the genetic material and prevents the replication mechanism from functioning and performing properly. dna damage and mutation have different biological consequences. while most dna damages can undergo dna repair, such repair is not 100% efficient.

i think that c)gold was found there

but i am not sure
