If the above DNA strand is the template (antisense) strand and the DNA molecule is transcribed that produced a functional mRNA. Assuming there are no mutations, the said mRNA is then brought to the site of protein synthesis,a. what would be the amino acid sequence of the synthesized polypeptide chain?b. how many possible kinds of tRNA molecule that will bring the 2nd amino acid observing wobble hypothesis? List down their anticodons.A peptide has the sequence NH 2-phe-pro-lys-gly-phe-pro-COOH. Which of the following sequences in the coding strand of the DNA could code for this peptide?

Complete the DNA-to-amino acid table for three consecutive codons with the appropriate nucleotides and amino acids using a codon table. Nucleotide and amino acid options can be used multiple times or not at all. 5' to 3' DNA strand 3' to 5' DNA strand transcribed mRNA tRNA anticodon amino acid arginine cysteine leucine T A U A T G A U arginine leucine A proline T A U Answer Bank A G G с с T T A A U glutamic acid U G C G с с glutamic acid G G G с с G C arginine C G с GWhich property of DNA makes it more stable than RNA in the basic environment? The negative charge of the phosphate on DNA repels the negative charged base. Histones block access to all except a few nucleotides that act as linkers. The 2' -H in DNA is not reactive, whereas the 2' -OH of RNA is reactive under basic conditions. RNA forms elaborate structures that are susceptible to alkaline digestion. O DNA precipitates in basic solutions, making it unreactive.
