Answer: D) Any protein made from mutated DNA will not function properly
Explanation: During replication, DNA polymerase double-checks and removes every newly added wrong nucleotide. This is to maintain high fidelity because if a mutated DNA is synthesized during replication, it will also lead to synthesis of an RNA with an altered nucleotide sequence during transcription and consequently lead to the synthesis of a protein that will not function well during translation.

Answer:
one mutated recessive one and one mutated dominant gene
Explanation: These disorders are usually passed on by two carriers. Their health is rarely affected, but they have one mutated gene (recessive gene) and one normal gene (dominant gene) for the condition.
Answer:
Explanation:
Type of gene(s) found in cancer cells -------------- oncogene
type of gene(s) found in normal cells and cancer cells ----- oncogene, proto-oncogene
gene(s) that could code for a normal growth factor ---------------- proto-oncogene
gene(s) whose absence can cause cancer --------- tumor suppressor gene (anti-oncogene)
type of gene(s) found in normal cells ----------- oncogene and proto-oncogene
gene(s) whose presence can cause cancer ------------- oncogene
type of gene(s) found only in cancer cells ------- oncogene
Oncogene are the switch off of proto-oncogene and are responsible for abnormal cell growth. Oncogene are found in all normal cells. They are mutated proto-oncogene.
