Why is it so important that the order of base pairs stays the same?
The order of base pairs in DNA contains vital genetic information that determines the sequence of amino acids in proteins. Any alteration in the sequence could result in changes to the protein structure, affecting its function or leading to genetic mutations. Consistent base pair order ensures accurate replication and maintenance of genetic information during cell division.
What is directly responsible for the sequence of amino acids in a protein?
The sequence of amino acids in a protein is directly determined by the sequence of nucleotides in the gene that codes for that protein. This process occurs during protein synthesis, where the genetic information is transcribed from DNA to mRNA and then translated into a specific sequence of amino acids.
How is DNA through the process of protein synthesis responsible for traits?
DNA carries the instructions for building proteins through the process of protein synthesis. These proteins are responsible for various traits in an organism, such as physical characteristics and biochemical functions. The sequence of DNA nucleotides determines the sequence of amino acids in proteins, which ultimately determines an organism's traits.
What determines the different shapes and functions of proteins?
The sequence of amino acids in a protein determines its unique shape and function. This sequence is specified by the DNA sequence of the gene that encodes the protein. Through a process called protein folding, the amino acid chain folds into a specific three-dimensional shape that enables the protein to carry out its specific function.
If a mutation occurred during the formation of a protein that substituted an amino acid with a reactive R group for one that had a nonreactive R group how might this affect the reactivity?
The mutation could potentially increase the reactivity of the protein if the substituted amino acid with the reactive R group allows for new chemical reactions to occur. On the other hand, if the nonreactive R group is essential for the protein's normal function, the mutation could disrupt the protein's activity. Ultimately, the effect on reactivity would depend on the specific amino acids involved and the role they play in the protein's structure and function.
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 does DNA determine a protein's shape?
DNA determines a protein's shape by determining the sequence of the amino acids in a protein.
How does a DNA molecule determine structures of a specific protein?
The DNA sequence will determine the amino acid sequence known as the protein's primary structure. As the protein is folded into the secondary, tertiary and quatranary structures, the amino acid molecules will determine the shape
How does a DNA molecule determined the structure of a protein?
The DNA sequence will determine the amino acid sequence known as the protein's primary structure. As the protein is folded into the secondary, tertiary and quatranary structures, the amino acid molecules will determine the shape
What determine the shape and function of a protein?
Conformation is what determines a protein's unique set of functional and otherwise shapes.
Where do the instructions for building a protein come from originally?
The instructions for building a protein come from the DNA molecule. DNA contains the genetic code that is transcribed into messenger RNA (mRNA). The mRNA is then translated into a sequence of amino acids, which determine the structure and function of the protein.
How does the sequence of DNA affect the function of a protein?
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.
How can a mutation in a DNA base sequence cause a change in protein?
dna in a cell needs protein and chromosomes.
Why is the correct sequence of DNA bases important to the production of proteins?
The sequence of DNA bases determines the sequence of amino acids in a protein, which in turn affects the protein's structure and function. Any changes in the DNA sequence can lead to alterations in the protein produced, potentially impacting its functionality. Therefore, a correct sequence of DNA bases is crucial for the accurate production of proteins.
What is the role of the DNA molecules in the synthesis of proteins?
they determine the sequence of amino acids in a protein i think
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.
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.
