lara31 [8.8K]

Answer: AUG GU UGG AAU

Explanation: Since it's a point mutation which only effects single nucleotide; so in CGA codon, the second codon, deletion mutation has been occured while mRna strand is going to be synthesized, this has shortened the length of the resulting protein developed from these codons.

Since RNA contains uracil instead of thymine, so in place of thymine (T), uracil has been placed.

Suppose the North American plate is moving away from the Eurasian plate at a rate of 2 cm per year. The eastern-most point of No
Archy [21]

The correct answer is - 1,180 km.

North America and Europe move away from one another, though the two plates, the North American and Eurasian are merging together on the other side. Since the rate of moving away is 2 cm per year, and the current distance is 1,184 km between North America and Europe, the distance between them 200,000 years ago was 1,180 km.

To get to the result we only need to multiply the number of years with the annual movement

2 x 200,000 = 400,000

Than divide the result with 100,000, as that is how much cm are in one km

400,000 / 100,000 = 4

And we get 4 km, in this case 4 km less, thus the distance between the two, 200,000 years ago, was 1,180 km.
