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.
What else can I help you with?
What sequence best represents the relationship between DNA and the traits of an organism?
DNA contains the instructions for building proteins, which determine an organism's traits. The sequence is: DNA → RNA → proteins → traits of an organism. This process is known as the central dogma of molecular biology.
What is the relationship between an organism's DNA and protein specificity?
An organism's DNA encodes the instructions for building proteins through the sequence of nucleotides in its genes. This sequence determines the specific sequence of amino acids in a protein, which in turn influences its structure and function. Therefore, the DNA sequence directly influences the protein specificity in terms of its unique composition and role in the organism.
Can An insertion of a DNA base into a gene can affect an organism?
Yes, the insertion of a DNA base into a gene can significantly affect an organism. This change can alter the amino acid sequence of the resulting protein, potentially impacting its function. Depending on the nature of the insertion, it may lead to a nonfunctional protein, a gain of function, or even cause diseases. In some cases, such mutations can also contribute to evolutionary adaptations.
The coded information in a DNA molecule directly determines the formation of?
Proteins. The sequence of nucleotide bases in DNA codes for the sequence of amino acids in proteins, which ultimately determines their structure and function. This process is known as protein synthesis.
What is the molecular sequence which is the blueprint for a protein?
The molecular sequence that serves as the blueprint for a protein is the sequence of nucleotides in a gene, encoded in DNA. This sequence is transcribed into messenger RNA (mRNA), which carries the genetic information from the nucleus to the ribosomes. There, the mRNA sequence is translated into a specific sequence of amino acids, forming a protein. The order of nucleotides ultimately determines the structure and function of the protein.
How does DNA sequence determine protein function?
The DNA sequence encodes the sequence of amino acids in a protein, which in turn determines the protein's structure and function. The specific sequence of amino acids determines how the protein folds into its three-dimensional structure, which ultimately determines its function in the body. Any changes in the DNA sequence can result in alterations to the protein structure and function, leading to potential health consequences.
How do changes in DNA affect the production and function of proteins?
Changes in DNA can affect the production and function of proteins by altering the sequence of amino acids in the protein. This can lead to changes in the structure and function of the protein, which can impact various cellular processes and functions in the body.
What sequence best represents the relationship between DNA and the traits of an organism?
DNA contains the instructions for building proteins, which determine an organism's traits. The sequence is: DNA → RNA → proteins → traits of an organism. This process is known as the central dogma of molecular biology.
How can mutation in DNA affect what proteins are made by the cell?
Mutations in DNA can lead to changes in the sequence of amino acids in a protein, affecting its structure and function. This can result in altered protein function, loss of function, or gain of new function, impacting cellular processes and potentially leading to diseases.
How can a point mutation affect the protein created by the gene?
A point mutation can affect the protein created by a gene by changing a single nucleotide in the gene's DNA sequence. This change can alter the amino acid sequence of the protein, potentially leading to a different protein being produced. This can impact the protein's structure and function, which may result in a variety of effects on the organism.
Why is the correct sequence of DNA bases important to the production of proteins?
The sequence of DNA is used, through a process involving the different types of RNA, into amino acids to produce the proteins. The sequence is what determines the amino acids used, and thus an incorrect sequence will build a different protein.
The sequence of subunits in a protein is most directly dependent on the?
The sequence of subunits in a protein is most directly dependent on the sequence of nucleotides in the gene encoding that protein. The nucleotide sequence dictates the amino acid sequence through the genetic code, and the amino acid sequence determines the protein's structure and function. Any changes in the nucleotide sequence can lead to alterations in the protein's composition and potentially its function.
How might an error during transcription affect the protein that is produced?
The protein might be unable to function.
Does a DNA mutation always result in a change to the protein?
No, a DNA mutation does not always result in a change to the protein. Some mutations are silent and do not affect the protein's function.
Which sequence best represents the correct order of events involved for this mutation to affect the traits expressed by this cell?
Mutation occurs in the DNA of the cell. Mutation leads to changes in the sequence of amino acids in a protein. Altered protein function affects the traits expressed by the cell.
What is the relationship between an organism's DNA and protein specificity?
An organism's DNA encodes the instructions for building proteins through the sequence of nucleotides in its genes. This sequence determines the specific sequence of amino acids in a protein, which in turn influences its structure and function. Therefore, the DNA sequence directly influences the protein specificity in terms of its unique composition and role in the organism.
What is the specific expressed sequence of DNA that codes for a protein in this genetic sequence?
The specific expressed sequence of DNA that codes for a protein in this genetic sequence is called a gene.
