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.
Answer:tailing at 3' end protects mRNA from attack by 3' exonuclease and 5' capping is useful for recognition of mRNA
Explanation:
The mRNA formed and released from the DNA template is known as primary transcript. In mammalian system, it undergoes intensive modification to become the mature mRNA.
Post transcription processing includes removal of Introns, splicing of exons, poly-A tailing at 3'end and capping at 5' end.
The Poly-A tailing at 3' end occurs in the nucleoplasm, the 3' end is polyadenlated involves with 20-250 nucleotides long. This tail protects mRNA from attack by 3' exonuclease activity
5' end capping end also is done in the nucleus. The cap is useful in recognition of mRNA by the translating machinery.
The CPT code to be reported in radiological services is 74400-26
76604. This codes mean Ultrasound,
chest (includes mediastinum), real time with image documentation. CPT stands for “Current Procedural
Terminology”. In every medical,
diagnostic, or surgical procedure or service has an associated 5-digit CPT code
assigned to it.
Explanation:
Plants consume carbon dioxide—a significant greenhouse gas—in the process of photosynthesis. The reduction of carbon dioxide in the atmosphere has an indirect cooling effect.
B.
If enough evidence is found for the theory, it will become a law.
