Question

question 10
transcription can be best described as the:
degradation of trna.
reading of mrna codons by trna.
replication of dna.
synthesis of mrna.
question 11
nacl would move through the cell membrane in which direction?
both into and out of the cell
into the cell
out of the cell
neither into nor out of the cell
question 12
which of the following terms is synonymous with tumor?
anaplasia
hyperplasia
neoplasm
benign

Explanation:

• Question 10: Transcription is the process where DNA is used as a template to synthesize mRNA. It is not related to tRNA degradation, reading of mRNA codons by tRNA (which is translation), or DNA replication.
• Question 11: The movement of NaCl across the cell - membrane depends on the concentration gradients of Na⁺ and Cl⁻ ions inside and outside the cell. It can move both into and out of the cell to reach equilibrium.
• Question 12: A tumor is also known as a neoplasm. Anaplasia refers to the loss of cell differentiation, hyperplasia is an increase in the number of cells, and benign is a type of tumor classification rather than a synonym for tumor.

Answer:

Question 10: synthesis of mRNA.
Question 11: Both into and out of the cell
Question 12: Neoplasm
