Answer:
The correct answer is option B. exocytosis.
Explanation:
Exocytosis is a process that helps in transport secretory products to the plasma membrane through the cytoplasm in a cell. In this process, the materials are transported out of the cell with the help of vesicles.
Some of the examples of the exocytosis are the secretion of the enzymes, proteins, peptide hormones and antibodies from the cell linings of the stomach that help in the digestive process.
Thus, the correct answer is option B. exocytosis.
Answer:
(A). mRNA.
Explanation:
During protein synthesis, information present in DNA as triplet codons gets transferred to mRNA molecule, by the process of transcription. The mRNA than gets transported to the cytosol, where it associates with ribosomes.
Ribosomes are known as protein factories of the cells as they provide platform for translation. During translation, information present in mRNA is used to translate polypeptide chain or protein as each codon codes for a specific amino acid.
Thus, the correct answer is option (A).
