Answer:
15%
Together, adenine and thymine compose 70% of the segment. This means that 30% of the section is composed of guanine-cytosine pairs. Since these two bases will be equal in quantity, 15% of the DNA section will be cytosine bases.
Answer:
causing degradation of transcription factors and changing which genes are expressed
Explanation:
Ubiquitination (addition of ubiquitin to a protein) is the first step in protein degradation process, and it directs protein to the proteasome for degradation. This process involves three steps with specific groups of enzymes to perform them, which are activation with ubiquitin-activating enzymes, conjugation with ubiquitin-conjugating enzymes and ligation with ubiquitin ligases. These enzymes would be most likely to regulate gene expression by causing degradation of transcription factors and changing which genes are expressed.
Answer:To be considered a source of water pollution, the source must include a chemical.
Explanation:
Both viruses and animal cells require another cell to reproduce. Also, they both have a nucleus a cell membrane.
