What happens to the resulting polypeptide when 1 nucleotide pair is lost from the middle of the coding sequence of a gene?
A deletion is a serious mutation. This would cause a shift in the reading frame and every triplet after that one, including that one, would not be one nucleotide off. This would most likely cause every amino acid to change (although they could stay the same because there are multiple codings for each amino acid). Depending on where this was in the DNA chain it can cause a small loss of function or a total loss of function of that particular protein.

What would happen if a single nucleotide mistake were made in the replication process?
it cased that a another nucleotide replaces primary nucleotide and happens mutation.
What are three main types of gene mutations what happens in each gene?
The three main types of gene mutations are point mutations, insertion mutations, and deletion mutations. Point mutations involve changes to a single nucleotide base. Insertion mutations involve the addition of extra nucleotide bases. Deletion mutations involve the removal of nucleotide bases in a gene sequence.
What happens during the biological process of translation?
During translation, the mRNA sequence is read by ribosomes, which assemble amino acids into a protein chain according to the codons on the mRNA. Transfer RNA (tRNA) molecules bring specific amino acids to the ribosomes based on the codons in the mRNA, resulting in the synthesis of a protein based on the genetic code.
What happens a DNA nucleotide that contains guanine is accidentally substituted for a DNA nucleotide that contains thymine?
This substitution would result in a mismatched base pair, with guanine pairing with thymine instead of cytosine. During DNA replication, this can lead to a mutation in the DNA sequence if not corrected by the DNA repair mechanisms. The mutation can potentially affect the functioning of the gene where it occurs.
What is dominant negative mutation?
A negative mutation is one which is harmful to the organism. The result of a negative mutation is a non-sense protein. Examples of negative mutations include:a frame shift mutation - codons are read wrongan insertion mutation - insertion of a sequence of extra nucleotidesa deletion mutation - deletion of a chain of nucleotidesa non-sense mutation - results in the creation of a non-sense proteina transition mutation - exchange of purines to pyrimidines thus changing the nucleotide sequence and resulting in a mutation.
What happens when translation takes place?
During translation, the cell uses messenger RNA (mRNA) as a template to produce a specific protein by decoding the nucleotide sequence into a corresponding sequence of amino acids. This process occurs within ribosomes, where transfer RNA (tRNA) molecules bring in the amino acids based on the mRNA codons, leading to the formation of a polypeptide chain that folds into a functional protein.
Is a polypeptide chain a polymer?
Yes, a polypeptide chain is a polymer because it is made up of repeated units called amino acids bonded together through peptide bonds. The sequence of amino acids in a polypeptide chain gives rise to its unique structure and function.
What would happen if a single nucleotide mistake were made in the replication process?
it cased that a another nucleotide replaces primary nucleotide and happens mutation.

The three main types of gene mutations are point mutations, insertion mutations, and deletion mutations. Point mutations involve changes to a single nucleotide base. Insertion mutations involve the addition of extra nucleotide bases. Deletion mutations involve the removal of nucleotide bases in a gene sequence.
What happens in a substitution mutation and how does it impact the genetic code?
In a substitution mutation, a single nucleotide in the DNA sequence is replaced with a different nucleotide. This can change the amino acid that is coded for, potentially altering the protein that is produced. This can lead to changes in the genetic code, which may result in a different protein being produced or a non-functional protein.
What happens to the growing of polypeptide?
It will either continue growing, or develop into a functional protein.

What happens if there's a mutation in your body cells?
The sequence of the nitrogenous bases changes (and sometimes some bases are added to the sequence or completely removed).
What happens a DNA nucleotide that contains guanine is accidentally substituted for a DNA nucleotide that contains thymine?
This substitution would result in a mismatched base pair, with guanine pairing with thymine instead of cytosine. During DNA replication, this can lead to a mutation in the DNA sequence if not corrected by the DNA repair mechanisms. The mutation can potentially affect the functioning of the gene where it occurs.
What important function happens inside the ribosomes?
A ribosome is A cellular organizm that manufactures polypeptide chains that will become proteins.

What happens during a substitution mutation and how does it impact the genetic code?
During a substitution mutation, a single nucleotide in the DNA sequence is replaced with a different nucleotide. This can lead to a change in the amino acid that is coded for, potentially altering the protein that is produced. The impact on the genetic code depends on whether the substitution results in a silent mutation (no change in the amino acid) or a missense mutation (change in the amino acid), which can affect the function of the protein.
