An in vitro translation system can synthesize peptides in all three reading frames of the RNA template. When 5' - UCUCUCUC-(UC)n-UCUCUCUC - 3' was used as the template in this in vitro translation system, the synthesized peptides contained 50% each of serine and leucine. When 5' - CCUCCUCCU-(CCU)n-CCUCCU - 3' was used as the template, the synthesized peptides contained 33.3% each of serine, leucine, and proline. Deduce the codon for proline.
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
In a batch process, the reaction takes place in the presence of an acid medium. The acid is drained from the reaction vessel at the rate of 15ml/s as a result of the density difference of the acid from the reacting component. To avoid wastage of acid, it is recycled to an acid tank which has 1000 L capacity. The acid drained from the reaction vessel, picks up 50 g/L solids from the reactor. Acid is fed once again to the process from acid tank. When the process is started, the acid is almost pure in the tank as a result of filtration. As the reaction proceeds, acid in the tank gets more and more contaminated with the solids. The concentration of the solids should not exceed 100 g/L from the process point of view. The batch time is 16h. Estimate whether the concentration of the solids will exceed 100g/L during the batch reaction.
Consider the following statements and choose the correct answer:
1. The structural genes direct the synthesis of cellular proteins through messenger RNA (mRNA)
2. The promoter gene determines whether or not the structural genes are to be repressed by the repressor
3. The regulator gene directs the synthesis of a protein which may be an active repressor or an inactive repressor
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:
Word 2010 has a particular template that it uses when you first open the program. This template contains default styles, no text and you also use it when you create new, blank documents. As you customize styles, marcos and other elements these settings are automatically stored in this template. What is the name of this template file?
