Explanation:
A. Shine-Dalgarno Sequence:
- This is a binding site found in the messenger RNA (mRNA) in prokaryotic organisms. It is found upstream of the start codon AUG and aids in the initiation of protein synthesis
B. SRP:
- Signal Recognition Protein (SRP). This acts by binding to the bacterial ribosome, which as a result restricts protein synthesis.
C. NLS:
- Nuclear Localisation Signal is a short amino acid sequence, which is responsible for transporting proteins from the cell cytoplasm into the nucleus. The NLS is also responsible for the development of the nuclear envelope of the cell.
D. Ubiquitin:
- Found predominately in Eukaryota, the ubiquitin is a protein that aids in the control of other proteins within the organism.
E. Specificity Factor:
- Also known as the sigma factor, is responsible for the initiation of bacterial transcription. It is recycled during the transcription process and is only required at the initiation of transcription.
F. CRP:
- cAMP Receptor Protein (CRP) is involved in catabolite (glucose) repression and serves as an inducer in the process.
Answer:
This demonstrate the transforming principle.
Explanation:
Griffith performed the experiment on the virulent bacteria and non- virulent bacteria. The non- virulent bacteria produce rough colonies and did not cause pneumonia. The virulent bacteria produces smooth colonies that kill the mice and caused pneumonia.
When Griffith mixed the on virulent bacteria and heat killed virulent bacteria he found that the mice were killed. He concluded that there was transforming principle that turns the non- virulent bacteria into virulent bacteria from the heat killed bacteria. Something, has been transferred from the heat killed bacteria to the non- virulent bacteria. Later, he found that dead mice blood sample contained both the non-virulent rough bacteria strains and virulent smooth strains of bacteria.
I think C) availability of water is your best answer because alot of organisms count on water as a major resource because they need it to survive so a lack or a gain in the amount of water will majorly effect an ecosystem.
