How much GTP is used in translation?
2 GTPs, 1 GTP for the positioning of the incoming tRNA and the other for the translocation of the ribosome for the continuation of the elongation process are used in the elongation stage of the translation. – 1 GTP is used to release the newly formed polypeptide chain in the termination step of translation.
What is CCA in tRNA?
Abstract. Transfer RNA nucleotidyltransferases (CCA-adding enzymes) are responsible for the maturation or repair of the functional 3′ end of tRNAs by means of the addition of the essential nucleotides CCA.
What is the tRNA for CAA?
Thus, the correct answer is option ‘GUU’.
How many ATP does it take to charge a tRNA?
2 ATP
The energy cost of incorporating one aminoacyl-tRNA into a protein is 2 GTP, but the total cost of incorporating one amino acid into a protein is 4 high-energy bonds (2 ATP + 2 GTP) when the energy needed to charge a tRNA is included.
How many ATP and GTP are required for polymerisation of 100 amino acids?
Explanation: When one tRNA brings amino acid to form an amino acid polypeptide chain it needs energy molecules which is one ATP, so a t-RNA carrying 100 amino acids will require 100 ATP molecules to form 100 amino acid polypeptide chain. And in this process of polymerization, one GTP molecule is required.
What is the anticodon for GTA?
Solution
| Asparagine (Asn) | Histidine (His) | |
|---|---|---|
| mRNA codon | AAU or AAC | CAU or CAC |
| DNA | TTA or TTG | GTA or GTG |
| tRNA anticodon | UUA or UUG | GUA or GUG |
What is the mRNA of CCA?
| Amino Acid | Coding DNA Strand Base Triplets Not Transcribed | Transfer RNA Anticodons Complementary To M-RNA Codons |
|---|---|---|
| glutamic acid | GAA, GAG | CUU, CUC |
| glutamine | CAA, CAG | GUU, GUC |
| glycine | GGT, GGC, GGA, GGG | CCA, CCG, CCU, CCC |
| histidine | CAT, CAC | GUA, GUG |
Is AAA a start codon?
The genetic code can be read in multiple ways depending on where the reading starts. For example, if the base sequence is GGGAAACCC, reading could start from the first letter, G and there will be 3 codons – GGG, AAA, and CCC.
What is TAC in mRNA?
The other strand of DNA doesn’t synthesize mRNA is called the non-template strand, or more commonly the coding strand. The beginning of a gene is defined by the three bases of the template strand, TAC, which is transcribed into the start codon, AUG.
How do you convert DNA into RNA?
Next, we must convert the RNA into DNA. We use an enzyme called “reverse transcriptase” to create a complementary DNA (cDNA) sequence from the RNA fragment. This creates hybrid molecules that are a combination of RNA and cDNA.
