The role of the cap recognition proteins is 

 to catalyze the reaction between the two amino acids on the charged tRNA molecules 

 to bring the large and small ribosomal subunits together to produce a functional ribosome

 to allow the small ribosomal subunit to recognize the mRNA

 to utilize it's helicase activity to stop complementary binding of the mRNA

Solutions

Expert Solution

Correct answer is : to allow the small ribosomal subunit to recognise the mRNA.

Reason:The small ribosomal subunit attach to the mRNA by binding to the 5 ' cap i.e 7 methyl guanosine cap at the 5' terminus of the mRNA. This helps the ribosome to scan downstream for the AUG initiation codon

Many proteins are enzymes (they catalyze reactions). Thus, it is necessary to review how reactions take place. Reduced organic compounds tend to contain stored energy in C–H bonds. As a general rule, the greater the number of C–H bonds, the greater the amount of potential energy stored in the molecule. Answer each question in the chart as it relates to the two reactions shown at the top. Be sure to be prepared to explain the reasoning behind your answers. Reaction...
