dna in a cell needs protein and chromosomes.
What else can I help you with?
Synthesis of a defective protein may result from an alteration in?
the DNA sequence coding for the protein, leading to a mutation. This mutation can cause a change in the amino acid sequence, affecting the protein's structure and function. Defective protein synthesis can also result from errors in the transcription or translation processes.
Can a point mutation cause a change in one single nucleotide in a DNA sequence?
Yes, a point mutation can cause a change in one single nucleotide in a DNA sequence.
How can a mutation in a DNA base sequence cause a change in protein?

What is a genetic mutation that does not result in a change in the amino acid sequence of the resulting protein?
It is neutral mutation. Codons are made up of 3 base pairs. This gives 64 different combinations, but there are only 20 amino acids, so some different codons will code for the same amino acid. When the base pair that is changed doesn't cause a change in the amino acid it codes for, then ultimately nothing happens
Explain why the addition of an extra base in a DNA sequence would change the message carried by a DNA molecule?
The addition of an extra base in a DNA sequence would cause a frameshift mutation, shifting the reading frame of the genetic code. This would alter the codons specifying amino acids in the protein sequence, leading to a different protein being produced.

When a nitrogenous base is inserted or delete how does that affect the amino acid sequence?
The amino acid sequence is shifted, and this kind of mutation is called a frame shift mutation. All of the amino acid sequence after the mutation will be changed, which will cause a change in shape of the protein, which will then probably result in a nonfunctional protein, since the shape of a protein determines its function.
Can a point mutation cause a change in one single nucleotide in a DNA sequence?
Yes, a point mutation can cause a change in one single nucleotide in a DNA sequence.

How do mutations affect translations?
A frameshift mutation may cause a change in the codon sequence, specifically the 3-base sequence which is responsible for coding a specific amino acid. A different protein, a non-functional one, or no protein at all may be the result of this change.
How many amino acids would this protein have if a mutation occurred and the 7th dna base pair of the dna strand was changed from a-t to t-a?
This mutation would cause a frameshift mutation, shifting the reading frame of the DNA sequence. Most likely, this would lead to a completely different protein being translated, resulting in a protein with a different sequence of amino acids from the original protein. The number of amino acids would depend on the specific changes in the protein sequence caused by the frameshift mutation.
Why does a detetion mutation usually cause more defect during protein synthesis than point mutation?
Mutation usually causes the entire base sequence to defect. This usually happens during the protein synthesis.
How can a point mutation alter the final structure of a protein?
In a point mutation, one nitrogen base is substituted for the correct base. Since most amino acids can be coded for by more than one codon, there may be no consequence to this mutation. However, sometimes a point mutation results in an incorrect amino acid being added to the amino acid sequence of the protein. This can cause a change in the shape and therefore function of the protein, which can be a harmful mutation. Two genetic disorders caused by a point mutation are cystic fibrosis and sickle cell anemia.
In your own words write a definition for the word mutation?
mutation: a change in the sequence of DNA to cause a unusal trait
