Answer:
3 nucleotides in an RNA molecule.
Explanation:
Protein synthesis in the cell produced by RIBOSOMES requires a lot of energy and it's has the highest mass in living organisms. Protein synthesis involve the process where Messenger RNA (MRNA) message is converted to a polypeptide product. The transcription in the cell produced messenger RNA. The translation of mRNA template converts nucleotide-based genetic information into a protein product. The protein sequences contain about 20 Ami o acids and each amino acids is defined by three nucleotides sequence which is called triplet codon. The relationship between nucleotides codon And amino acids is called genetic code
Answer:
The restriction endonucleases in bacteria (b) they provide a defense mechanism against infection by viruses
Explanation:
The restriction endonucleases is a protein that is produced by the bacterias that interacts with the DNA of them and gives protection to the bacterial cell by defending against viruses.
Is important to remember that viruses go into different organisms just with a copy of DNA that wants to replicate inside of them creating more and more copies until it breaks the hosting cell and this is how the infection spreads. This protein restricts (that's the reason of its name) or stops the replication stage of the virus DNA by cutting it into many pieces stopping in this way the spread of the infection and the death of the bacteria.
The answer is; UV (ultraviolet)
The security pens use UV light to illuminate some marking on an object,such as a watermark, to identify its authenticity or owner. The markings are usually invisible to the naked eye under visible light. The marks are only visible when illuminated with UV light. This is because the marking is made of a fluorescent material that absorbs light of a shorter wavelength (this case UV) and emits a longer wavelength (this case visible light).
