Which of the following are ways that DNA can undergo mutation? A. During DNA replication, the wrong base is added to the strand
as it is being built. B. A virus inserts its DNA into the DNA of another organism. C. High-energy waves like UV light or radiation physically damage the DNA. D. A repair DNA polymerase fixes a damaged DNA strand.
High-energy waves like UV light or radiation physically damage the DNA
Explanation:
Mutation is the change or alteration that occur in the DNA sequence or nucleotides sequence of an organism which is caused by mistakes when the organism is copied or environmental factors such as UV light.
Ultraviolet light cause mutations by activating the SOS repair systemof which is a part of i a new DNA polymerase that has no power to edit e but has the ability to move past the thymine dimer and synthesize DNA, This lead to cells able to replicate but with a high frequency of mutations.
The TCF transcription factor will bind <u>less</u> frequently with the cell's DNA, resulting in <u>decreasing</u> transcription."less, decreased
Active canonical WNT flagging outcomes in enlistment of β-catenin to DNA by TCF/LEF relatives, prompting transcriptional actuation of TCF target qualities.
The extra translation factors have been recommended to enroll β-catenin and tie it to DNA.
The genome-wide example of β-catenin DNA official in murine intestinal epithelium, WNT -responsive colorectal malignant growth (CRC) cells and HEK293 early stage kidney cells.
The two classes of β-catenin restricting locales.
The top notch speaks to most of the DNA-bound β-catenin and co-limits with <em>TCF4, the noticeable TCF/LEF relative in these cells.</em>
