What is mRNA built during?
mRNA is built during the process of transcription, which is the first step in gene expression. It involves the synthesis of mRNA from a DNA template by RNA polymerase. The mRNA molecule serves as a blueprint for protein synthesis during translation.
What are the 6 steps in protein synthesis simplied?
The steps in protein synthesis are: transcription, where DNA is copied into mRNA; mRNA processing, where the mRNA transcript is modified; translation, where the mRNA is read by ribosomes to synthesize a polypeptide; and post-translational modifications, folding, and transport of the protein to its functional location.
MRNA joins with what in the cytoplasm?
mRNA joins with ribosomes in the cytoplasm during translation to facilitate the synthesis of proteins.
What is the genetic code in mRNA that signals the start of protein synthesis?
AUG
What type of RNA transcribes the DNA code for protein synthesis?
mRNA
How does mRNA get out of the nucleus and into the cytoplasm for protein synthesis?
mRNA is transported out of the nucleus through nuclear pores in a process called mRNA export. Once in the cytoplasm, the mRNA binds to ribosomes where protein synthesis occurs.
What part of the DNA is copied in protein synthesis?
In protein synthesis, the DNA is copied into mRNA (messenger RNA) during the process of transcription. The mRNA then carries the genetic instructions from the DNA to the ribosomes, where protein synthesis occurs.
In what direction does the ribosome read mRNA during protein synthesis?
The ribosome reads mRNA in the 5' to 3' direction during protein synthesis.
Is mRNA translated from 5' to 3' during the process of protein synthesis?
Yes, mRNA is translated from 5' to 3' during the process of protein synthesis.
Where does a tRNA bind to an mRNA molecule during the process of protein synthesis?
A tRNA binds to an mRNA molecule at the ribosome during the process of protein synthesis.
Where does mRNA travel to within the cell during the process of protein synthesis?
mRNA travels to the ribosomes within the cell during the process of protein synthesis.
Can mRNA leave the nucleus to carry genetic information for protein synthesis?
Yes, mRNA can leave the nucleus to carry genetic information for protein synthesis.
What is the significance of mRNA shape in the process of protein synthesis?
The shape of mRNA is important in protein synthesis because it determines how the mRNA molecule interacts with other molecules involved in the process. The specific shape of mRNA helps to guide the ribosomes in reading the genetic code and synthesizing the correct protein. If the mRNA shape is altered, it can affect the efficiency and accuracy of protein synthesis.
What is the role of RNA polymerase in the synthesis of mRNA?
RNA polymerase is an enzyme that helps to transcribe DNA into mRNA by reading the DNA template and creating a complementary RNA strand. This process is essential for the synthesis of mRNA, which carries the genetic information from the DNA to the ribosomes for protein synthesis.
Why is it essential that tRNAbinds to both an aminoacid and an mRNA codonduringprotein synthesis?
since mRNA codon signals the beginning of protein synthesis and aminoacids are necessary for reading the codon
What binds to the mRNA during the process of protein synthesis?
During the process of protein synthesis, ribosomes bind to the mRNA to read and translate the genetic code into a protein.
Do ribosomes translate mRNA into proteins during the process of protein synthesis?
Yes, ribosomes are responsible for translating mRNA into proteins during the process of protein synthesis.
