A single base substitution mutation is least likely to be deleterious when the base change results in _____.
A single base substitution mutation is least likely to be deleterious when the base change results in a codon that specifies the same amino acid as the original codon.
What is the effect of single base substitution mutation?
A substitution mutation can cause the following: Change in the coding of amino acids codon to a particular stop codon resulting in an incomplete protein, which is usually non-functional. Can cause Silent mutations where a codon change can encode the same amino acid resulting in no changes in the protein synthesized.
What is base substitution mutation?Base substitutions are the simplest type of gene-level mutation, and they involve the swapping of one nucleotide for another during DNA replication. For example, during replication, a thymine nucleotide might be inserted in the place of a guanine nucleotide.

what type of muscle cells are arranged in sheets or layers with adjacent muscle cells electrically connected by gab junction
Answer:
smooth muscle
Explanation:
Smooth muscle fibers are spindle-shaped and, unlike skeletal muscle fibers, have a single nucleus; individual cells range in size from 30 to 200 μm. Smooth muscle fibers are often found forming sheets of tissue and function in a coordinated fashion due to the presence of gap junctions between the cells.

Which type of cell is being described in the following passage? The cell has a large surface area due to its biconcave shape. It is able to store lots of haemoglobin as it does not have a nucleus.
Answer:
Red blood cell
Explanation:
Red blood cell has a large surface area due to its biconcave shape. It is able to store lots of haemoglobin as it does not have a nucleus.
Red blood cells have the form of a flat disk, resembling a doughnut, that is spherical, has an indentation in the middle, but is not hollow.
What are the different characteristics of Red blood cell?Red blood cells are minuscule. Unlike white blood cells, red blood cells don't have a nucleus, which makes it easier for them to alter shape and circulate around your body.
Red blood cells are disc-shaped, biconcave structures without a nucleus or organelles. Red blood cells' adaptation to transfer gases is visible in their form.
The surface area through which Hades can diffuse is expanded. Additionally, the cell's structure brings oxygen-carrying hemoglobin molecules closer to it.
Therefore, Red blood cell has a large surface area due to its biconcave shape. It is able to store lots of hemoglobin, as it does not have a nucleus.
