Yes, a mutation can occur without affecting the phenotype at all. For example, a point mutation may change a nucleotide in a codon, but sometimes, the codon can still code the same amino acid, so the mRNA strand can still make the same protein.

What cell mutation does not impact the phenotype of the organism because the protein remains unchanged?
It is possible for a point mutation to not change the sequence of amino acids in a protein. This will result in the protein being unchanged and will not affect the phenotype.
Mutations in introns are less likely to affect phenotype then mutation in exons?
Mutations in introns are less likely to affect phenotype because introns are not translated into protein, unlike exons which contain coding regions for proteins. Introns are involved in regulation of gene expression through processes such as alternative splicing, but mutations within introns typically have a more subtle impact on gene expression compared to mutations in coding regions (exons).
A mutation in a gene may not affect an individual's phenotype because?
the mutation may occur in a non-coding region of the gene, resulting in no change to the protein produced. Additionally, the mutation may be silent, meaning it does not alter the amino acid sequence of the protein. In some cases, the organism may have redundant genes that compensate for the mutation, allowing it to function normally.
What is the main question to ask when considering the effect of a mutation?
The main question to consider when evaluating the effect of a mutation is how it alters the organism's phenotype or function. This involves assessing whether the mutation impacts protein structure or function, gene regulation, or any other biological processes that could affect the organism.
What One example of a mutation that would not affect an organisms phenotype?
A silent mutation is an example of a mutation that would not affect an organism's phenotype. This type of mutation occurs in a non-coding region of DNA, such as an intron, and does not change the amino acid sequence of the protein produced. Therefore, it has no impact on the organism's outward appearance or characteristics.
Can mutation beneficial?
Yes mutations are the basis of evolution as they provide variance in the phenotype that could have evolutionary advantages
What is it called when replication is messed up?
Mutation occurs, if a mutation is recessive it is not expressed in the phenotype, if however it is dominant when passed on in the offspring it is expressed in the phenotype.
Is a mutation deleterious?
A deleterious mutation has a negative effect on the phenotype, and thus decreases the fitness of the organism. (A harmful mutation)
What is it called when DNA replication messes up?
One ma be born with physical, and or mental illness. Such as fragile X syndrome.
What is the phenotype of a mutation?
The phenotype of a mutation refers to the observable physical or biochemical characteristics of an organism that result from the mutation. It can include traits such as altered appearance, behavior, or function compared to the wild-type or non-mutated organism.
Which gene mutation is less likely to result in a phenotype change and why?
phylogeny
How does a mutation in a gene affect the order of DNA based?
A mutation in a gene can happen by addition, deletion or substitution of base pairs. This means that the order of the bases will change- a new base may be added, a base may be lost, or one base may be substituted for another. The result of these mutations is that it causes the DNA to code for a different protein. If a mutation occurs in a sex cell, the mutation can be passed on to an offspring and affect the offspring's phenotype.
