Answer:At times parts of the gene can change entirely, leading to alteration of the product. There are many types of gene mutations, but all types of mutation can potentially affect the cell and its function.
Explanation: A publisher can misprint a book in several ways. The publisher can miss words, make spelling erros, mix up paragraphs or delete some text entirely.With these kinds of errors, the text will be inaccurate, and the reader can get confused. Mutations in genes happen similarly.

Explanation:
Scientists call the organisms that decompose organic matter decomposers, saprobes or saprotrophs. Fungi and bacteria are not restricted to decomposing leaves and other plant materials.
Transcription factors are necessary for an initiation of transcription at a regulated gene but not sufficient.
Transcription is the first step of gene expression in which DNA molecule is copied (transcribed) into RNA (mRNA) by RNA polymerase. The process of transcription is divided into three phases:
1. Initiation
• RNA polymerase with transcriptional factors bind to gene promoter Transcription factors can enhance the interaction between RNA polymerase and a DNA sequence- promoter, encouraging the expression of the gene. Such transcription factors are called activators. Otherwise, when the gene expression is inhibited, factors are called repressors and they bind to sequence –operator.
• RNA polymerase unwinds DNA double helix (transcription bubble is formed)
2. Elongation
• RNA polymerases adds nucleotides complementary to DNA
3. Termination
• RNA polymerase gets to stop codon (transcribes a sequence of DNA known as a terminator)
• Formed complementary RNA strand is released from DNA-RNA complex
<u>substrate</u> fits into the <u>active site</u>, so the answer is C
