Answer:
What are the statements? please mention
Explanation:
B) Rust, because it has tightly arranged hyphae
I believe a simple change in DNA results in Mutation. A mutation is a random spontaneous changes that occur in the genetic make up of an organism ( in the DNA sequences). The mutation are either due to mistakes when DNA are being copied or as a result of environmental factors such as UV light and cigarette smokes among other mutagens. Mutations may be either gene mutation (permanent alteration in the DNA sequence that makes up a gene) or chromosomal mutation.

We presented with several statements after the question. Only one of these statements are correct.
DNA replication is the process in which a single strand of DNA, acting as the parent strand, forms two new strands of DNA. DNA transcription is the process of copying the information of the DNA strand and delivering this information into a strand of mRNA. These processes may sound similar, but there are key differences. We must look at the building blocks of DNA and RNA. Both structures are composed of four different bases, however, only three of these bases are shared between structures and they each have a unique fourth base. In DNA, the fourth base is thymine and it is uracil in RNA. We already established that DNA replication forms new strands of DNA, which would use thymine by default. DNA transcription results in formation of mRNA which would therefore use uracil.
The correct statement from the choices provided is the following:
Thymine is used in replication while uracil is used in transcription.
