How does the sequence of DNA bases affect the protein product?
The DNA sequence of a gene determine the amino acid sequence of the resulting protein. Thus any changes in DNA sequence can result in changes in protein function . This is called mutations. Mutations can be good,bad or neutral depending upon whether the effect of mutation is positive , negative or unnoticed.
What will most likely happen if there is a change in the base sequence of this molecule?
What will most likely happen if there is a change in the base sequence of this molecule? 1) The molecule will be converted into an inorganic compound. The amino acid sequence may be altered during protein synthesis.
What are the sequence of DNA that codes for a protein?
Each sequence of three nucleotides, called a codon, usually codes for one particular amino acid. (Amino acids are the building blocks of proteins.) A type of RNA called transfer RNA (tRNA) assembles the protein, one amino acid at a time.
What does the sequence of DNA bases determine?
DNA sequencing is a laboratory technique used to determine the exact sequence of bases (A, C, G, and T) in a DNA molecule. The DNA base sequence carries the information a cell needs to assemble protein and RNA molecules. DNA sequence information is important to scientists investigating the functions of genes.
What does the sequence of bases determine?
The sequences of bases in a DNA molecule will determine the amino acid sequence in the protein that it encodes for. The bases are arranged in triplets where one triplet will encode for one amino acid in a non-overlapping fashion.
What is a change in the sequence of bases in DNA?
DNA is a dynamic and adaptable molecule. As such, the nucleotide sequences found within it are subject to change as the result of a phenomenon called mutation.
How does DNA code for proteins step by step?
The DNA remains in the cell nucleus but the production of the protein occurs in the cytoplasm. This requires the help of mRNA. DNA has the code for a protein which mRNA has to copy and then take that copy out of the nucleus to an other organelle called a ribosome. There the copy is translated into the protein.
What causes a change in the sequence of amino acids?
The percentage of their proteins with the same molecular composition is high A change in the order of DNA bases that code for a respiratory protein will most likely cause A change in the sequence of amino acids determined by the gene A certain mutant bacterial cell cannot produce substance X.
What happens if base sequence of DNA is changed?
What will happen if a base sequence of a strand of DNA is changed from A-T-G to A-T-C? The m-RNA will be changed from U-A-C to U-A-G The inability of an organism to produce certain proteins can occur when an organism is lacking an enzyme needed to combine Amino acids
What does the diagram represent in protein synthesis?
The diagram represents a step in protein synthesis.
