Answer:

The corresponding RNA would have "CUG" in place of "CUA"

Explanation:

The nucleotide sequence of the DNA template strand determines the sequence of RNA and the nucleotide sequence of mRNA specifies the amino acid sequence of the protein. Guanine in DNA template pairs with cytosine, adenine with uracil and thymine with adenine base in the RNA.

A DNA template strand with sequence "GAT" would specify the sequence "CUA" in the corresponding DNA. If "T" in the sequence of template strand is replaced with "C", then the corresponding RNA would have sequence "CUG".

However, amino acid leucine has a total of six codons: UUA, UUG, CUU, CUC, CUA, and CUG. Therefore, both the mRNA would code for the same amino acid.

What is air pressure? At what elevation is air pressure the highest? Why?

Step2247 [10]

Answer:

With greater depth of the atmosphere, more air is pressing down from above. Therefore, air pressure is greatest at sea level and falls with increasing altitude. On top of Mount Everest, which is the tallest mountain on Earth, air pressure is only about one-third of the pressure at sea level.

VLD [36.1K]

In this population, what will occur is that there will be no evolution. Mutation is neccessary and important because they provide varitations that can result in evolutionary change. Other factors needed for evolution to occur are migration and selective pressure.
