What carry instructions for making proteins?
mRNA
Observe how the mRNA interacts with the ribosome in the simulation. How is this interaction similar to what actually happens in translation?
The interaction between mRNA and ribosomes in the simulation is meant to reflect the process of translation that occurs in cells. During translation, the ribosome uses the information stored in the mRNA molecule to synthesize a protein. The ribosome moves along the mRNA molecule and reads its codons (sets of three nucleotides) to determine which amino acids should be added to the growing polypeptide chain. In the simulation, the mRNA molecule is represented as a linear sequence of codons, and the ribosome is represented as a moving object that recognizes and interacts with the codons. The ribosome moves along the mRNA and recognizes each codon by binding to it. This interaction is similar to what happens in real cells, where the ribosome recognizes codons by binding to specific sites on the mRNA molecule. In the simulation, the ribosome can also interact with tRNA molecules, which bring the correct amino acids to the ribosome for incorporation into the growing polypeptide chain. This is similar to what happens in real cells, where tRNA molecules bring the correct amino acids to the ribosome for use in protein synthesis. Overall, the interaction between mRNA and ribosomes in the simulation is meant to closely resemble the process of translation that occurs in cells.
What is the function of the cap and tail on eukaryotic mRNA?
The cap and tail on eukaryotic mRNA play important roles in mRNA stability and translation. The 5' cap protects the mRNA from degradation and helps in the initiation of translation. The poly(A) tail at the 3' end of mRNA also plays a role in mRNA stability and regulation of translation.
Is cDNA complementary to mRNA?
Yes, cDNA is complementary to mRNA.
What is the scientific term for writing the mRNA message in a cell?
The creation of mRNA is called transcription. mRNA is being transcribed from the DNA template.
What is the order of how a cell changes DNA messages to protein?
DNA -> transcription -> pre-mRNA -> mRNA processing -> mRNA -> translation -> protein
The 5' cap of mRNA is important for what?
The 5' cap of mRNA is important for several reasons: it protects the mRNA from degradation by exonucleases, helps in the recognition and binding of the mRNA by the ribosome for translation, and is essential for efficient splicing of introns.
Does translation involve the formation of mRNA?
No, transcription involves the formation of mRNA.
What is the relationship between chromosome mRNA and proteins?
The mRNA is transcribed into proteins
What is the stop codon in most molecules of mRNA?
stop codon on mRNA
What base does mRNA have that DNA does not?
Uracil replaces Thymine as a base in mRNA.
Are codons found in mRNA or tRNA?
mRNA is made up of anticodons
