Blood glucose levels for obese patients have a mean of 100 with a standard deviation of 15. A researcher thinks that a diet high in raw cornstarch will have a positive or negative effect on blood glucose levels. A Sample of 30 patients who have tried the raw cornstarch diet has a mean glucose level of 140.
Test the hypothesis that the raw cornstarch had an effect.. Use 5% level of significant

In bacteria, researchers have isolated strains that carry
mutations within the tRNA genes. These mutations can
change the sequence of the anticodon. For example, a
normal tRNATrp gene would encode a tRNA with the
anticodon 3’-ACC-5’. A mutation could change this
sequence to 3’-CCC-5’. When this mutation occurs, the
tRNA still carries a tryptophan at its 3’ acceptor stem,
even though the anti-codon sequence has been altered.

A. How would this mutation affect the synthesis of
proteins within the bacterium?

B. What does this mutation tell you about the recognition
between tryptophanyl-tRNA synthetase and tRNATrp ?
Does the enzyme primarily recognize the anticodon or
not?
