Briefly describe the process of translation and include the appropriate RNA molecules and high-energy phosphates.
Translation is the process in which polypeptide chain ( protein) is formed with the help of ribosomal RNA (rRNA ), Messenger RNA( m - RNA) and Transfer RNA(t- RNA).
The three main steps involved are
Firstly activation of amino acid takes place by formation of amino acyl AMP enzyme complex. Then following steps continue one by one.
1 Initiation:- Ribosome assemble around the m- RNA and t- RNA along with the amino acid come to lie at the p site of ribosome.
2 elongation:- the tRNA transfers it's amino acid after reading the codon on mRNA and move to A site and come come out from exit site ... another activated tRNA molecule come to lie over the p site and some process continues until the complete polypeptide chain is formed.
3 termination:- when peptidyl tRNA encounter the stop cidon( UAA, UAG, UGA) , then ribosomal folds the polypeptide into the final structure.
Briefly describe the process of translation and include the appropriate RNA molecules and high-energy phosphates.
In the process of translation, RNA molecules do all of the following except Catalyze the formation of peptide bonds Bring amino acids to the site of translation Carry the message that was transcribed from DNA Provide the site for translation Catalyze the formation of bonds in a sugar-phosphate backbone
DIAGRAM and BRIEFLY explain how energy from high energy electron carriers is converted to ATP during respiration in mitochondria and aerobic bacteria. Label each process involved in energy conversions, and label two of the proteins involved in the final steps of making ATP. (compare this to ATP production during Photosynthesis) [hint: discuss electrons, gradients, and phosphates, and the proper terms for the pathways involved.]
