What is the molecular weight of a polynucleotide chain consisting of ten adenine-containing nucleotides? Answer in...
A researcher creates random copolymers by mixing polynucleotide phosphorylase with guanine and adenine nucleotides at a ratio of 5 guanine nucleotides to 1 adenine nucleotide. What amino acids could be produced by this mixture, and in what theoretical proportions would you expect them? (Hint: you need to figure out what codons you can make, in what proportions, and then use that to figure out which amino acids you’d expect.)
help please

What is the molecular weight of a peptide chain with 40 residues? 0.36 Da 60 Da O 4.4 kDa 5.5 kDa
ԿԱՆՉՈ» 2. Genes are made of DNA nucleotides. The gene for the beta chain of hemoglobin is 1,734 nucleotides in length and is located on the human chromosome 11. The mutation responsible for sickle-cell anemia affects a single nucleotide, which in turn changes a single amino acid. (9 pt) a. How are these nucleotides joined together to form a long polynucleotide chain? Name the relevant nucleotide constituents important for making the linkage. (see Slides 5-7 of Lecture 4b) (2 pt)...
Assume you were given a mixture consisting of one molecule each of all possible sequences of a smallish protein of molecular weight 4800 daltons. If the average molecular weight of an amino acid is, say, 120 daltons, how much would the sample weigh? How big a container would you need to hold it? What does this calculation tell you about the fraction of possible proteins that are currently in use by living organisms (the average molecular weight of proteins is...
