Apart of an mrna has the sequence ccg. which change to this sequence would indicate a missense mutation? a. cca b. cca c. ccu d. cgg

The codon CCG codes for Prolinejust like A, B and C (A and B are the same so perhaps a typo)all these codons (CCA, CCU, CCG and CCC) code for proline. The one that doesn't code for proline is the last one (D), CGG - this one codes for tryptophan.

You can check these on a codon table.

So your answer is D. CGG

D. CCG

Explanation:

Apex Approved :3

1. (1.2kw)x(15/60hours) = .3kwh --> a

2. (5kw)x(90/60hours)x(8cents/kwh) = $0.60 --> d

3. microwave --> 1200 watts = (1.2kw)x(6/60hours) = .12kwh

coffee-maker --> 900 watts = (.9kw)x(10/60hours) = .15kwh

therefore, it requires more energy for the coffee-maker to do the same amount of work.

so the answer is a.

the index of refraction of the second medium is higher. i just took the test trust me !
