Canary Islands, July 2020, option B, question 8
Mutations are sometimes beneficial because they create variability, but other times they have serious or even fatal consequences.
Canary Islands, June 2021, question 15
15. A person is a collection of approximately 30 trillion cells. Each time one of them divides to generate a daughter, the entire genome must be copied; in that process, totally random copy errors called mutations can be made.
Aragon, July 2021, question 5
During the last year, we have heard repeatedly in different media that different variants of a virus can appear because it mutates. We know that this is not unique to viruses and that a eukaryotic cell can also undergo mutations. Answer the following questions: (2 marks)
a) What is a gene or point mutation? Briefly explain the types of gene mutation and the possible repercussions of these. (0.8 p)
b) What is a genomic mutation? (0.3 p)
c) And a chromosomal mutation? (0.3 p)
d) What is a mutagenic agent and what types are there? (0.3 p)
e) A group of individuals has been exposed to a potent mutagenic agent, undergoing gene mutations. Will their descendants inherit these alterations? Reason for the answer. (0.3 p)
