Q. How does the nucleus control protein synthesis?
The nucleus directs protein synthesis by synthesizing messenger RNA (mRNA) according to instructions provided by the DNA. Once an mRNA molecule reaches the cytoplasm, ribosomes translate the mRNA’s genetic message into the primary structure of a specific polypeptide.
Q. Does protein synthesis occur in nucleus?
Although it is universally accepted that protein synthesis occurs in the cytoplasm, the possibility that translation can also take place in the nucleus has been hotly debated. However, these mRNAs are likely to be in the perinuclear cytoplasm rather than within the nucleus.
Q. How is the nucleus involved in protein synthesis quizlet?
The nucleus controls protein synthesis in the cytoplasm by (1) Messenger RNA (mRNA) is transcribed in the nucleus from DNA instructions. –> (2) It then passes through nucleus pores into cytoplasm. –> (3) Finally, it attaches to ribosomes where the genetic message is translated into primary protein structure. 2.
Q. What three organelles take part in protein synthesis of the entire process of protein synthesis?
How is the nucleus involved in protein synthesis? Ribosomes make proteins for the cell and Mitochondria use sugar and oxygen to release energy that is used by the cell. ER helps make proteins (ribosomes) and also lipids. Chloroplasts turn sunlight, carbon dioxide, and water into food (glucose).
Q. What is the most active site of protein synthesis?
Ribosome
Q. What best describes the role of transfer RNA in protein synthesis?
Transfer RNA (tRNA) is the key to deciphering the code words in mRNA. These complex structures, which physically move along an mRNA molecule, catalyze the assembly of amino acids into protein chains. They also bind tRNAs and various accessory molecules necessary for protein synthesis.
Q. What converts mRNA into a protein translation transcription?
During transcription, the enzyme RNA polymerase (green) uses DNA as a template to produce a pre-mRNA transcript (pink). The pre-mRNA is processed to form a mature mRNA molecule that can be translated to build the protein molecule (polypeptide) encoded by the original gene.
