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.
The definition of a point mutation states that a mutations is a point mutation if it affects only one or few nucleotides in the DNA product. We have that DNA is read in frames of 3 nucleotides. If the starting point of one frame is changed, then all frames are changed because the frames are grouped by 3 nucleotides. We have that frameshift mutations not point mutations because a shift in the reading frame affects how the rest of the DNA is read. This is the case for insertion and deletion of a nucleotide; it changes the number of nucleotides and shifts the reading frame by 1. A missense mutation is a point mutation though; it involves substituting a nucleotide with a wrong one. It involves an error only in one place and it does not change the reading frame so it affects only one nucleotide.
The light red layer between the white lumen and blue lamina propria consist of epithelium cells.
<h3>What is a lamina propria?</h3>
A lamina propria is a type of connective tissue that is present and found under the thin layer of tissues covering a mucous membrane.
<h3 /><h3>Characteristics of the lamina propria</h3>
- It is a very large layer of connective tissue
- It divides the innermost layer from a layer of smooth muscle tissue.
- it is a light red layer barrier located between the white lumen and blue lamina.
- It is made up of epithelium cells.
- It is also found in the respiratory tract, the Gastrointestinal tract, and the urogenital tract.
Thus, the light red layer between the white lumen and blue lamina propria consist of epithelium cells.

Answer:
The term gene expression means the process by which the information encoded in our DNA is used to synthesize a functional product, such as a protein molecule or other cell structures.
