Which set of the following events occurs during the elongation step of translation?<br>P. Attachment of mRNA with the smaller subunit of ribosome<br>Q. Loading of correct aminoacyl-tRNA into the A site.<br>R. Formation of a peptide bond between the amino acyl-tRNA in the A site and the peptide chain that is attached to the peptidyl-tRNA in the P site.<br>S. Dissociation of the ribosomal subunits.<br>T. Translocation of peptidyl-tRNA from the A site to the P site of the ribosome.

Correct Answer: Q, R and T

An electronic device rearranges numbers step-by-step in a particular order according to set of rules. The device stops when the final result is obtained.
Input: 84 15 35 04 18 96 62 08
Step 1: 96 84 15 35 04 18 62 08
Step 2: 96 84 62 15 35 04 18 08
Step 3: 96 84 62 35 15 04 18 08
Step 4: 96 84 62 35 18 15 04 08
Step 5: 96 84 62 35 18 15 08 04
And Step 5 is the last step for this input. Now, find out an appropriate step in the following question following the above rule. Question:
Input: 16 09 24 28 15 04
What will be the third step for this input ?

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:

An electronic device when fed with the numbers, rearranges them in a particular order following certain rules. The following is a step-by-step process of rearrangement for the given input of numbers. Input :- 85 16 36 04 19 97 63 09 Step I :- 97 85 16 36 04 19 63 09 Step II :- 97 85 63 16 36 04 19 09 Step III :- 97 85 63 36 16 04 19 09 Step IV :- 97 85 63 36 19 16 04 09 Step V :- 97 85 63 36 19 16 09 04 (for the given input step V is the last step). Which of the following will be the last step for the given input ? Input :- 03 31 43 22 11 09

A word arranging device rearranges words step-by-step in a particular order according to set of rules. The device stops when the final result is obtained.

What will be the last step for this input ?

Consider the following statements.
1. Translocation of food occurs through phloem.
2. Translocation via phloem occurs in the form of sucrose.
3. Loss of bark or girdling harms the plant more than loss of leaves, as root starves due to stoppage of food conduction.
Which of the statements given above is/are correct about translocation of food?

A word arrangement machine, When given an input line of words, rearranges it in every step following a certain rule. Following is an illustration of an input line of words and various steps of rearrangement.
Input: gone are take enough brought station
Step 1: take gone are enough brought station
Step 2: take are gone enough brought station
Step 3: take are station gone enough brought
Step 4: take are station brought gone enough
And Step 4 is the last step for this input. Now, find out an appropriate step in the following question following the above rule. Question:
Input: car on star quick demand fat
What will be the third step for this input ?

Which of the following proteins bind to the ribosome and causes the dissociation of the two ribosomal subunits from mRNA?

First, the bond between the amino acid and the tRNA in the P site is cleaved, then the peptide bond is formed between the two amino acids.

During the formation of initiation complex the mRNA attaches to the 30 S subunit of ribosome which is then called

The peptidyl transferase center that catalyzes the peptide bond formation is located on the smaller subunit and consists entirely of rRNA.
