Which genetic change is best described by the following statement A random change in the base sequence of DNA results in an alteration of a polypeptide?
A point mutation is best described by this statement. Point mutations occur when there is a change in a single nucleotide base in the DNA sequence, which can lead to changes in the corresponding amino acid sequence of a polypeptide during protein synthesis.
If the 17th nucleotide in the original DNA were changed from T to A what mRNA would the new DNA code for?
If the 17th nucleotide in the original DNA changes from T to A, the corresponding mRNA would reflect this change during transcription. In DNA, adenine (A) pairs with uracil (U) in RNA, so the new mRNA sequence would replace the original nucleotide at that position with uracil. The exact mRNA sequence would depend on the surrounding DNA sequence, but the change would result in a different codon that could potentially alter the amino acid sequence of the resulting protein.
What sequence changes when a gene undergoes mutation?
When a gene undergoes mutation, the sequence of nucleotides in its DNA changes. This alteration can involve the substitution of one nucleotide for another, the addition or deletion of nucleotides, or larger rearrangements of the genetic material. These changes can affect the gene's coding sequence, potentially leading to altered protein function or expression, which may result in various phenotypic effects.
What is one way that changes can occur in a DNA sequence?
A radioactive carbon isotope can "convert" ... changing the chemistry of a codon.
What describes a mutation?
changes in the DNA sequence

What is a statement called that explains how variables affect each other called?
It is called a causal relationship or causal statement. This type of statement highlights the cause-and-effect relationship between variables, describing how changes in one variable can directly influence another variable.
The crusades have been called history's most successful failures ''which statement best explains this expression?
the crusades did not achieve thier original goals, but they brought about many desirable changes in europe.
Does the Statement of Comprehensive Income explain changes in Equity?
No, that is explained on the Statement of Changes in Owner's Equity. However, you do need to prepare a Statement of Comprehensive Income first in order to prepare the Statement of Changes.
What happens when a protein sequence changes?
When a protein sequence changes, it can impact the structure and function of the protein. This can result in altered protein-protein interactions, changes in enzymatic activity, or disruption of protein folding. In some cases, protein sequence changes can lead to diseases or abnormalities in cellular processes.
What statement best explains the overall impact impact of the age of discovery?
Exploration and the growth in world trade led to social, political and economic changes all around the world.Exploration and the growth in the world trade led to social, political, and economic changes all over the world.
What does the statement of changes in retained earnings consist of?
The statement of changes in retained earnings, also known as the statement of earned surplus, is documentation that only details the changes in earned capital: the net income and the dividends for a given period.
Changes in DNA sequence of a single gene are called?
Changes in a DNA sequence of a single gene is called a point mutation. These mutations can be harmful or not to the organism.
Which industries brought corresponding changes in labor needs?
sugar and tobacco
Are blue eyes a mutation?
No. Mutations are changes in a genomic sequence. Blue eyes are not changes.
