A DNA codon has the sequence GAT. What is the resulting tRNA anti-codon in the translation
process (using Watson-Crick base-pairing)?
Step by step
Solved in 2 steps
- What is the start codon? What are the stop codons? Do any of them code for amino acids?A tRNA anticodon has the base sequence CCG. Identify the DNA base sequence that was used to produce the codon that will bind it to this anticodon?If the anticodon of a molecule of tRNA has the sequence GAU, what was the original DNA sequence?
- Why must a polypeptide sequence begin with a designated Start codon?If the base sequence on one DNA strand is ATGGCCTAG, what is the sequence on the other strand of the helix? If the original strand serves as the template for transcription, what is the sequence on the new formed RNA strand?Using the codon table, identify a 5’-3’ sequence of nucleotides in the dna template strand for mRna coding for the polypeptide sequence NH2-PHe-Pro-lys-COOH.
- The template strand of a double helical segment of DNA consists of the following sequence: 5’-GTAGCCTTAAGCGATCACCGTCCGTATTACTAGTGGCCAGACTCTTTTCACTCTCATGTATAGTTG-3’ What will be the overall anti-codon sequence in tRNA?How can you identify the start codon in the mRNA sequence ?How many cases are there in which it would be possible to identify the first two nucleotides of a codon if the amino acid specified by it is known?
