Consider the following statements regarding genetic code and choose the correct answer:
1. The genetic code is degenerate
2. In all amino acids the first two bases are the same in all the codons that represent a particular amino acid
3. The number of codons an amino acid can claim is proportional to the frequency of the amino acid in proteins
4. Amino acids with codons ending in U or A also have codons ending in C or G respectively
Analysis of a hexapeptide using enzymatic cleavage reveals the following result:
• Amino acid composition of the peptide is: 2R, A, V, S, Y
• Trypsin digestion yields two fragments and the compositions are: (R, A, V) and (R, S, Y)
• Chymotrypsin digestion yields two fragments and the compositions are: (A, R, V, Y) and (R, S)
• Digestion with carboxypeptidase A yields no cleavage product.
Given: Trypsin cleaves at carboxyl side of R. Chymotrypsin cleaves at carboxyl side of Y. Carboxypeptidase A cleaves at amino side of the C-terminal amino acid (except R and K) of the peptide.
The correct amino acid sequence of the peptide is:
The peptide formation involves two amino acids covalently joined together between the carboxyl group of one amino acid and the amino group of another.
The common amino acids are also called as alpha-amino acids because they contain their amino group attached to the alpha carbon.
You are the network administrator for your company. Mike Nash is a member of the Administration group, and Nate Sun is a member of the Intern group. Both groups are in the same domain. On the intranet server, the Administration group is placed in the Security group, and the Intern group is placed in the Nonsecurity group. The Security group is then granted Full Control permission for the Sales virtual directory. Nate needs to update new sales information that is located on the Sales virtual directory. What should you do so that Nate can perform this task?
If 6 years are subtracted from the present age of Ayush and takes 25% of that then we get the present age of his only son. 4 years ago, his daughters age is 7 years more than his son. Sum of daughters present age and his wifes present age is 10 years more than Ayushs present age then find the present age of Ayush if average of present age of entire family is 30.25 yr?
PROTPARS counts the minimum number of mutations to change a codon for the first amino acid into a codon for the second amino acid, but only scores those mutations in the mutational path that actually change the amino acid.
Amino acids contain an amino group and an acidic group at different carbons
