Answer:
Sella Turcica occurs on the sphenoid bone.
Explanation:
Sella Turcica is the saddle shaped bone of the skull and acts as cephlaometric landmark. The inner aspect of sella turcica consists of hypophysis or pituitary gland.
Sella Turcica is present in the sphenoid bone of the skull just behind the tuberculum sellae and chiasmatic groove. The shrink pituitary gland is indicated by the empty Sella Turcica.
Primary structure, which is simply the sequence of amino acids in a polypeptide molecule.
Answer:
The correct answer is - D. All rocks were molten in that time period.
Explanation:
The early Precambrian era began 4.6 billion years ago. The formation of eath start from this era with dust and gas. The atmosphere at that time was too hot. It was like hades. The rocks were molten and appear to like an ocean of rocks.
Due to the molten rocks, there are no samples of rock from this area as it was too hot to be formed. There were boiling sulfur and gases were everywhere.
Bibliography is essential in determining its content. I hope this helped
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.
