How is a gene related to the sequence of nucleotides?
Genes are segments of DNA. DNA is made up of polymer of nucleotides joined together. When there is an alteration in the sequence of nucleotides, gene mutation occurs.
A random alteration in the sequence of DNA nucleotides that provides a new variant allele is called a?
gene mutation
What is a alteration in DNA?
An alteration in DNA refers to any change in the nucleotide sequence of the genetic material. This can include mutations, deletions, insertions, or rearrangements of DNA segments, which can occur naturally or be induced by environmental factors. Such alterations can affect gene function and expression, potentially leading to variations in traits or diseases. Depending on the nature and location of the alteration, it may have no effect, be beneficial, or cause harmful consequences to an organism.
A medical test indicates that a patient has a defective protein. This condition is most likely due to a change in the directions coded in the?
sequence of subunits in DNA.
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.
What is the point mutation of AGGCGTCCATGA?
A point mutation refers to a change in a single nucleotide in a DNA sequence. In the sequence AGGCGTCCATGA, any alteration of a single base pair would qualify as a point mutation. For example, if the first 'G' were replaced with an 'A', the mutated sequence would be AGGCGTCCATGA → AAGCGTCCATGA.
How does a permanent alteration of the nucleotide sequence impact genetic expression?
A permanent alteration of the nucleotide sequence can impact genetic expression by changing the instructions encoded in the DNA. This can lead to changes in the production of proteins, which are essential for various cellular functions. Mutations can result in abnormal or non-functional proteins, affecting the normal functioning of cells and potentially leading to genetic disorders or diseases.
What is the DNA sequence of an entire chromosome affected by?
The DNA sequence of an entire chromosome affected by a mutation would have specific changes in the sequence of nucleotide bases. These changes can vary in size and location, leading to alterations in the genetic information carried by that chromosome, which can impact gene expression and protein production. This alteration can result in genetic disorders or diseases.
Is aggcguc a sequence of DNA?
No DNA sequence wont have U (uracil), so it is an RNA sequence!
DNA sequence acgtt will give what mRNA base sequence?
The mRNA base sequence corresponding to the DNA sequence acgtt is ugcaa. The mRNA sequence is complementary to the DNA sequence, with thymine (T) in DNA being replaced by uracil (U) in mRNA.
What sequence of DNA bases with the DNA base sequence atgt?
TACA
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.
