How does the sequence of DNA affect the function of a protein?
The sequence of nucleotides in DNA molecule is equivalent and is closely related to an amino acid sequence in the protein molecule. If for any reason the sequence of DNA nucleotides changes it will be reflected in amino acid sequence in the protein. Moreover, the correct sequence of amino acid in the protein will form the correct three-dimensional structure, or tertiary structure, that will confer the biological activity to protein. If a wrong amino acid is translated from a mutated gene in the DNA could change the spatial structure of the protein and therefore modify or erase its biological function.
A change in which part of a gene is the result of a mutation?
A mutation can result in a change in the DNA sequence of a gene. This can involve a substitution of one nucleotide for another, an insertion or deletion of nucleotides, or rearrangement of the existing nucleotides. These changes can alter the protein produced by the gene and may lead to genetic disorders or other consequences.
Which demonstrates an insertion mutation of the sequence 5' GGGCCCAAA 3'?
An insertion mutation of the sequence 5' GGGCCCAAA 3' could involve adding one or more nucleotides into the original sequence. For example, if we insert an "X" between the second and third nucleotides, the mutated sequence would be 5' GGXGCCCAAA 3'. This change alters the original sequence and can potentially affect the resulting protein if this DNA sequence is part of a coding region.
What does a DNA molecule look like with a mutation?
A mutation is a change in the sequence of nucleotides that make up DNA. Changes can cause a change in phenotype when they change a gene or regulatory sequence, but can be silent mutations when a stretch of so called 'junk DNA' is affected. A mutation can be either a spontaneous occurrence or induced by environmental factors such as free radicals / ionising radiation. Mutation is considered to be the driving force behind evolution, regardless of where it all originates from: evolution (change) through mutation is a fact.
WhIch best describes the initial change cause by a DNA mutation?
A DNA mutation can lead to changes in the sequence of nucleotides in the DNA, which can alter the instructions for building proteins. These changes can result in the production of a faulty protein or a non-functional protein, which can affect the normal functioning of cells and potentially lead to disease or other conditions.

What can occur as a result of a change in the sequence of nucleotides in a strand of DNA?
The addition or deletion of a nucleotide can lead to a Frameshift mutation. The Frameshift mutation causes a "shift" in the reading frame of the codons in the mRNA. This may lead to the change in the amino acid sequence at protein translation.
A change in which part of a gene is the result of a mutation?
A mutation can result in a change in the DNA sequence of a gene. This can involve a substitution of one nucleotide for another, an insertion or deletion of nucleotides, or rearrangement of the existing nucleotides. These changes can alter the protein produced by the gene and may lead to genetic disorders or other consequences.
What is the impact of a frameshift mutation, where one or more pairs of nucleotides are removed from a gene, on the resulting protein product?
A frameshift mutation, where nucleotides are removed from a gene, can change the reading frame of the gene. This alters the sequence of amino acids in the resulting protein, leading to a non-functional or abnormal protein. This can have serious consequences on the protein's structure and function, potentially causing genetic disorders or diseases.
Can a point mutation be frameshift mutation?
No

Why is it bad for human to mutate their DNA?
DNA in genes codes for protein. The sequence of nucleotides on the gene determined the amino acid sequence of the protein. If there were to be a mutation that caused a change in the nucleotide sequence of the gene, the wrong protein would be produced. If the wrong protein is one that is essential to life (like important hormones or developmental factors), this could cause an irreversible error in the development of the individual. Mutations ultimately result in altering the physiology of the cell.
Chemical q causes the following change in the sequences of nucleotides?
Chemical q induces a mutation in the DNA sequence, leading to a change in the order or composition of nucleotides. This alteration can result in various effects, such as a change in protein structure and function, potential genetic disorders, or even cell death depending on the specific sequence affected. Further investigation and analysis would be needed to determine the precise impact of this mutation.
How can a mutation in a DNA base sequence cause a change in protein?
dna in a cell needs protein and chromosomes.
