This would result in a frameshift mutation. This would cause the protein, after translation, to be truncated and would most likely be non-functional. This is due to a change in the amino acid sequence and would stop the protein from forming the correct secondary and tertiary structures due to a change in the electrostatic/ hydrophobic/ h-bonding etc. parameters of the protein

If DNA has the sequence AAA then a segment of mRNA would be what?
If DNA has the sequence AAA, the corresponding mRNA segment would have the sequence UUU due to complementary base pairing during transcription. This mRNA sequence would then undergo translation in order to produce a protein based on the genetic information contained in the DNA.
Glutathione is a tripeptide of glutamic acid cysteine and glycine Referring to the list of codons in your text what is a possible base sequence for the DNA strand from which the messenger for glut?
One possible base sequence for the DNA strand coding for glutathione could be GAA (glutamic acid), TGC (cysteine), and GGA (glycine), following the standard genetic code for translation from DNA to amino acids. This would result in the mRNA sequence being CUU (glutamate), ACG (cysteine), and GGU (glycine).
How would the amino acid sequence produced by the mutant strand compare to the amino acid sequence produced by series 1?
The mutant strand would likely have a different amino acid sequence compared to series 1 due to the mutation in the DNA sequence. The mutant strand may result in changes in the protein structure and function if the mutation leads to a substitution, deletion, or insertion of a nucleotide in the coding region of the gene.
'suppose the DNA sequence gctatatcg was changed to gcgatatcg how would the products of transcription and translation be affected?
Transcription is the process in which DNA is converted to RNA by transcription factors. Translation is the process in which RNA is converted to proteins. The easiest way to remember this is by thinking of DNA as American-English and RNA as british-English. Anyone who knows either one of the languages can easily convert one of them to the other. Toilet becomes the loo. Sidewalk becomes the pavement, etc. This is because DNA has A-T (adenosine-thymin) and C-G (cytosine-guanine) while RNA has A-U (adenosine-uracil) and C-G (cytosine-guanine) bonds. The language is almost the same. From RNA to proteins however, the entire code, structure and function is altered beyond recognition. This is why you call it translation. The conversion of one language to a completely different one - like british to Chinese for example. So, the product of transcription is RNA and the product of translation is proteins.
What order of bases on mRNA will match a sequence on tRNA of UUA?
If the tRNA has the sequence UUA, then the mRNA it reads from will have the sequence complementary to UUA, which is AAU. RNA uses the nucleic acid uracil instead of the DNA counterpart, thymine.
What is a sequence that could result from an inversion of the sequence GAGACATT?
An inversion of the sequence GAGACATT could result in the sequence CATTCTC. This is because an inversion would flip the sequence and reverse its order.
What would the peptide sequence be like after translation?
The peptide sequence after translation would be a chain of amino acids formed based on the mRNA sequence. The order of amino acids in the peptide would be determined by the genetic code, where each three-nucleotide codon specifies a specific amino acid. This process occurs in the ribosome during protein synthesis.
Would a 3-nucleotide insertion result in a frameshift?
Yes, a 3-nucleotide insertion would typically result in a frameshift mutation because it would disrupt the reading frame of the genetic code. This can lead to a different sequence of amino acids being produced during translation and potentially alter the function of the resulting protein.
What would be the effect of a mutation that changed the c of the anticodon to a g?
The effect of the mutation is; there would be another amino acid that may form due to the change in sequence of the anticodon. change in the sequence of anticodon may result to different amino acid that may form.
What is the protein strand created from the mrna strand cagaaguuccucucgc?
The sequence of amino acids (forming a protein) that result from the mRNA strand CAG-AAG-UUC-CUC-UCG-C would be: Glutamine-Threonine-Phenylalanine-Leucine-Serine Each codon must be three bases long - therefore the end of this mRNA sequence 'C' cannot code for an amino acid. There would also need to be a stop codon at the end to complete translation.
If you translate a heptagon what would it turn out to be?
Translation would result in a congruent heptagon at a different location.
What would happen to translation if a ribosome skipped one nucleotide?
If a ribosome skipped one nucleotide during translation, it would result in a frameshift mutation. This would alter the reading frame of the mRNA sequence, leading to a nonfunctional or altered protein being produced. Frameshift mutations often have serious consequences as they can disrupt the normal functioning of the protein.
What would the formation of a main sequence star result from?
The accretion of matter due to gravity.
If DNA has the sequence AAA then a segment of mRNA would be what?
If DNA has the sequence AAA, the corresponding mRNA segment would have the sequence UUU due to complementary base pairing during transcription. This mRNA sequence would then undergo translation in order to produce a protein based on the genetic information contained in the DNA.
What would a single change in the sequence of nitrogenous bases in a DNA molecule most likely result in?
A mutation
What would happen to translation if a ribosome skipped one or more codons?
If a ribosome skips one or more codons during translation, it can result in a frameshift mutation. This mutation can alter the reading frame of the mRNA sequence, leading to the synthesis of a completely different protein with potentially nonfunctional or altered properties. The severity of the impact depends on where in the mRNA sequence the ribosome skips codons.
What would happen if the DNA sequence that coded for Cys was mutated in the third position from a U to an A?
This mutation would change the codon from UGU (coding for Cys) to UGA, which is a stop codon. As a result, translation would be terminated prematurely, leading to a truncated protein. This could disrupt the normal function of the protein or render it nonfunctional.
