What Is The Role Of Rna In Protein Synthesis

is that RNA uses uracil instead of the thymine in DNA. DNA replicates itself and RNA is synthesized from RNA on an as-needed basis. Their stability and reaction is also different. DNA is more stable and less reactive than RNA because of the deoxyribose sugar’s C-H bonds. It is stable in alkaline conditions; DNA has smaller grooves, which makes it harder for enzymes to “attack.” RNA is more reactive because of the ribose sugar’s C-OH, hydroxyl, bonds. Unlike DNA, it is not stable in alkaline conditions and has larger grooves, which allows it for the enzymes to “attack” easier.
2. Describe the structure and the role of the 3 types of RNA (tRNA, mRNA, and rRNA) during protein synthesis.
There are three types of RNA: mRNA, tRNA, and rRNA. Messenger
The mRNA has a 5’ noncoding sequence, a coding region, and a 3’ noncoding sequence. All are capped at the 5’ end, and most have a polyadenylation sequence at the 3’ end. The 5’cap and 3’poly(A) tail protects the mRNA against exonuclease attacks. Stem-loop structures in the 5’na 3’NCS, features in the coding sequence, and the AU-rich region in the 3’NCS is thought to play roles in mRNA stability. The mRNA consists of RNA nucleotides arranged in a single uncoiled chain. Transfer RNA (tRNA) contains about 75 nucleotides, three of which are called anticodons, and one amino acid. The tRNA reads the code and carries the amino acid to be incorporated into the developing protein. Each amino acid is joined to the correct tRNA by a specific enzyme using the energy form an ATP molecule. Each tRNA molecules I used repeatedly, picking up its designated amino acid in the cytosol, depositing this cargo at the ribose, and then leaving the ribosome to pick up another amino acid. T Transfer RNAs are also used to recognize the appropriated codons in the mRNA because the amino acids cannot recognize the codons. Transfer RNA molecules
