Indicate trueT statement below regarding the use of homologo

Indicate true(T) statement, below regarding the use of homologous recombination in meiosis. Milotic recombination starts with a double slandered break caused by errors in DNA replication Meiotic recombination occurs preferentially between DNA from maternal and paternal chromosome pain With the help of the t-loop structure, sheltering \"hides\" the telomere ends from the cell\'s double-strand break detector and repair systems True False These enzymes can recognize altered bases in DNA and catalyze their removal by hydrolyzing the glyosidic bond between the base and the deoxyribose sugar. Therefore, they can remove a purine or pyrimidine base from DNA. What enzyme sits it is referring to? DNA polymerases Trans lesion polymerases DNA helicases DNA glycosylases

Solution

Answer:

7. True

The logic of the mammalian telomere system is that the repeats synthesized by telomerase function as binding sites for shelterin. As a consequence, shelterin accumulates at all natural chromosome ends, where it prevents the activation of the DNA damage response. In turn, shelterin is thought to be required for the recruitment of telomerase, ensuring that this enzyme does not add telomeric DNA to broken ends that lack shelterin binding sites.

8. (D) DNA glycosylase

Base excision repair, involves a battery of enzymes called DNA glycosylases, each of which can recognize a specific type of altered base in DNA and catalyze its hydrolytic removal.
