Question

cancer cells which proliferate uncontrollably are likely deficient in which of the following processes? apoptosis growth hiding from immune system mitosis true or false 2 points transfer rna, or trna, can be thought of as an adapter molecule that serves as the physical link between the nucleotide sequence of nucleic mrna and the amino acid sequence of proteins. true false true or false 2 points endocytosis involves moving substances that are too large to pass through the membrane into the cell. true false

Explanation:

• For question 18: Apoptosis is programmed - cell death. Cancer cells often evade apoptosis, allowing them to proliferate uncontrollably. Growth is not the deficient process as cancer cells grow well. Hiding from the immune system is a different mechanism than the key process related to uncontrolled proliferation. Mitosis is normal in cancer cells but not the deficient process here.
• For question 19: tRNA has an anticodon that pairs with mRNA codons and carries the corresponding amino - acid, acting as an adapter between mRNA nucleotide sequence and protein amino - acid sequence.
• For question 20: Endocytosis is a cellular process that engulfs large substances and brings them into the cell when they cannot pass through the membrane directly.

Answer:

1. A. apoptosis
2. True
3. True
