How would the transcription of a eukaryotic gene be affected if a replication error changed the nucleotide?
Extra long proteins are likely to fold improperly and not function correctly. The overall health of the individual would be destroyed.
What else can I help you with?
Why is replication in experimental design?
Observed results are less likely to be affected by random chance.
Why is replication important and experimental design?
Observed results are less likely to be affected by random chance.
If a nucleotide pair were removed from a gene what would be affected?
If a nucleotide pair were to be removed from a gene, it would cause a frameshift mutation. This would alter the reading frame of the gene, leading to a change in the amino acid sequence of the protein encoded by that gene. This could potentially result in a nonfunctional or altered protein.
Why is it acceptable that translation and transcription errors are not corrected?
Translation and transcription errors are often left uncorrected because it is time-consuming and costly to identify and fix mistakes, especially in large volumes of text. Additionally, some errors may be deemed minor and not significantly impact the overall understanding of the content. Prioritizing corrections based on the importance of the information and the resources available is common practice.
What is the DNA sequence of an entire chromosome affected by?
The DNA sequence of an entire chromosome affected by a mutation would have specific changes in the sequence of nucleotide bases. These changes can vary in size and location, leading to alterations in the genetic information carried by that chromosome, which can impact gene expression and protein production. This alteration can result in genetic disorders or diseases.
How would the transcription of eukaryotic gene be affected if a replication error changed the nucleotide sequence of the termination signal for that gene?
Extra long proteins are likely to fold improperly and not function correctly. The overall health of the individual would be destroyed.
How is DNA replication affected by a lack of mRNA?
Not at all. mRNA is not involved in DNA replication as it is involved in transcription and translation.

How would RNA polymerase be affected if the repressor protein were not bound to the proper site on a gene?
If the repressor protein is not bound to the proper site on a gene, it would not block the RNA polymerase from transcribing the gene. This would lead to the expression of the gene, as the RNA polymerase can then proceed with transcription.
If someone was missing an amiono acid how would transcription and translation be affected?
whenever an amino acid is missing it means there is deletion mutation. deletion mutations have deleterious effects on the transcription and translation as the reading frame is disturbed causing a change in gene.
What event will increase the frequency of a mutation in a population over time?
Mutation is the alteration of the nucleotide sequence of an organism, virus, or gene. A mutation can be caused by many factors like radiation and chemical exposure, inadequate nutrition, drastic changes in the environment, or an error in DNA replication. The frequency of occurrence of a particular mutation in the gene pool can be affected by drift, natural selection, sexual selection.
How is the process of DNA replication affected by the presence of 3' to 5' DNA strands?
The presence of 3' to 5' DNA strands can hinder the process of DNA replication because DNA polymerase, the enzyme responsible for adding new nucleotides to the growing DNA strand, can only add nucleotides in the 5' to 3' direction. This means that the 3' to 5' DNA strands cannot be replicated continuously and may cause delays or errors in the replication process.
What happens to a cell if it lack the enzyme DNA polymerase?
If a cell lacks DNA polymerase, it would not be able to replicate its DNA properly during cell division. This could lead to errors in the DNA sequence, potentially causing mutations and impairing the cell's ability to function correctly. Ultimately, this could result in cell death or contribute to the development of diseases such as cancer.
Explain the effect of penicillin on prokaryotic and eukaryotic cells?
Penicillin inhibits the synthesis of bacterial cell walls by targeting the enzymes involved in their production, which are specific to prokaryotic cells. In contrast, eukaryotic cells have different cell wall structures and are not affected by penicillin. This makes penicillin selectively toxic to bacteria, making it an effective antibiotic while sparing eukaryotic cells.
