What change in DNA base sequence that codes for a respitory protein will most likely cause?
a change in the sequence of amino acids. -P
What happens when there are changes in a gene?
The protein that the gene codes for changes or may even cease to be produced, depending on the change to the gene.
What is an exon's role in DNA?
The exon codes for the opening sequence of DNA for protein synthesis. It is a sequence of nucleotides that code for the RNA to begin transcription of the DNA to RNA protein.
What does gene mean?
A gene is part of DNA. It is a sequence that specifically codes for a protein.
What contains the codes for the sequence of amino acids in protein?
Generally DNA. But the DNA sequence gets transcribed into messenger RNA (mRNA) which the mRNA gets translated by ribosomes into a polypeptide and later into a protein.
What change in DNA base sequence that codes for a respitory protein will most likely cause?
a change in the sequence of amino acids. -P
What is a sequence in DNA that codes for a protein and thus determines a trait?
A gene is a DNA sequence that codes for a protein.
What happens when there are changes in a gene?
The protein that the gene codes for changes or may even cease to be produced, depending on the change to the gene.
Why can some gene mutatuions be harmful while others have no effect?
Let's consider a simple example: protein-coding genes. Mutations, or changes in the DNA sequence of the gene, can alter the amino acid sequence of the protein it codes for, if the new sequence translates into different amino acids. Because the genetic code is degenerate, some amino acids are specified by multiple codons, so some mutations may not alter the amino acid sequence at all. Such mutations, called synonymousmutations, have no affect on the protein. Mutations that alter the amino-acid sequence of the protein, called non-synonymousmutations, may or may not have an affect. Most proteins can tolerate some changes to that sequence and not be significantly affected, but if the sequence change is large enough, or occurs at a critical point so that the structure of the protein is significantly altered, then the protein may become non-functional. If that protein is essential to an organism, such a mutation may be lethal.
What is a type of nucleic acid that carries the codes for making proteins?
DNA is the nuceic acid.Base sequence codes for protein.
What is an exon's role in DNA?
The exon codes for the opening sequence of DNA for protein synthesis. It is a sequence of nucleotides that code for the RNA to begin transcription of the DNA to RNA protein.
What determines what proteins DNA code for?
The sequence of basis on the DNA molecule is what directs the sequence of amino acids in the protein molecule - that's how it all links together! So, the sequence of bases in DNA codes for the sequence of amino acids of a protein.
The sequence of amino acids that makes up a protein molecule is determined by the sequence of?
The primary structure of a protein is the sequence of amino acids in the protein. This is determined by the sequence of bases in the DNA ie by the genetic code. Each group of three bases in DNA codes for one amino acid in the protein ie it is a triplet code.
What does gene mean?
A gene is part of DNA. It is a sequence that specifically codes for a protein.
Why is it bad for human to mutate their DNA?
DNA in genes codes for protein. The sequence of nucleotides on the gene determined the amino acid sequence of the protein. If there were to be a mutation that caused a change in the nucleotide sequence of the gene, the wrong protein would be produced. If the wrong protein is one that is essential to life (like important hormones or developmental factors), this could cause an irreversible error in the development of the individual. Mutations ultimately result in altering the physiology of the cell.
What contains the codes for the sequence of amino acids in protein?
Generally DNA. But the DNA sequence gets transcribed into messenger RNA (mRNA) which the mRNA gets translated by ribosomes into a polypeptide and later into a protein.
What is another name for three nucleotides in a row which encode for a protein?
A sequence of three nucleotides is a codon which codes for an amino acid that will be placed into a protein.
