Why might the insertion or deletion of three base pairs in a gene be less harmful...
Which of the following mutations would cause the most harmful effect: 1) a single base insertion near the beginning of the coding sequence or 2) a three base deletion towards the end of the coding sequence.
How do scientists create GMOs in the lab? - both gene deletion and gene insertion - gene insertion - gene deletion Spontaneous chemical reactions are: - endergonic and release energy - exergonic and their products contain more energy - exergonic and release energy Humans metabolize by: - ACR and sometimes anaerobic cellular respiration - ACR and photosynthesis - fermentation only In a balanced chemical reaction, - the subscripts balance the number of molecules and the arrow points to the reactants...
Will an insertion or a deletion of three nucleotides result in a frameshift mutation? Explain why or why not.
Using these types of genetic changes: Base substitution, Transition, Transversion, Missense mutation, Nonsense mutation, Insertion, Deletion, Frameshift mutation Label these genetic changes (a-e). More than one answer may apply to each answer. a. GC->CG in the protein coding region on a gene. b. GC->TA in a GAA glutamate codon c. Loss of three bases GAA for a glutamate codon d. GC->CG in a tRNA gene e. GC->AT in the ribosome binding site of a mRNA
Why is an insertion or deletion more likely to result in a damaging mutation than a point mutation? 1.Point mutations only change two or three nucleotides 2.Point mutations never change the amino acid that is called for in the protein 3.Insertions/deletions change all codons that follow them, unless they are indels of 3, 6, 9, etc 4.Point mutations cannot result in a stop codon, whereas insertions and deletions can.
describe how deletion of one base in a gene or a substitution of one base in gene would affect translation?
Which of the following mutations would be most likely to have a harmful effect on an organism? (A) a deletion of three nucleotides near the middle of a gene (B) a single nucleotide deletion in the middle of an intron (C) a single nucleotide deletion near the end of the coding sequence (D) a single nucleotide insertion downstream of, and close to, the start of the coding sequence In this problem, why (c) cannot be the answer?? Single nucleotide deletion...
Due to mutations there could be some insertion of deletion which makes some palindromes not palindromes any more. For example, GCCACCG is a palindrome. Due to deletion, this sequence might be changed to CCACCG (“G” was deleted). QUESTION: design an algorithm which takes an input string and return a palindrome by inserting the smallest number of letters. You are allowed to insert characters at any position of the string. For example, AAT can be turned into palindrome TAAT by one...
The BRCA1 gene is very large, spanning roughly 100,000 base pairs. However, the functional mRNA from this gene is only 7,800 bases long. This difference is best explained by: A. Only a small region of the gene called ‘the exons’ are transcribed. B. The primary transcript is processed to remove many large introns. C. Unneeded regions of the mRNA at the 5’- and 3’-ends are removed during processing D. The mRNA is partially degraded after it is transcribed.
4. Briefly (one or two sentences) explain why polyamides (shown below) can inhibit gene transcription. (2 points) Recognition of All 4 Base Pairs go w
