What is the last step in transcription?
The excising of the introns from the mRNA and the adding of the poly A tail and guanine repeats to the mature mRNA so that it now exits the nucleus to begin translation.
What is the maximum length of a polypeptide encoded by an mRNA that is 45 nucleotides long?
15
What carry instructions for making proteins?
mRNA
How long is mRNA?
According to "Elementary Biochemistry" by J. Davies and B. Shaffer Littlewood, mRNA contains 100-5000 N-containing bases, which is also the # of nucleotides. I guess the size of the mRNA is related to the size of the protein molecule that is being synthesized. What is the largest protein made in the human body?
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 features of the mRNA make the mRNA last longer?
Viagra makes your penis last longer.

A messenger RNA mRNA is 336 nucleotides long including the start and stop codons the number of amino acids in the protein translated from this mRNA is?
100
What is the maximum length of a polypeptide encoded by an mRNA that is 45 nucleotides long?
15
What carry instructions for making proteins?
mRNA
If an mRNA is made up of 60 bases how many codons does it contain and how many amino acid does it code for?
A codon is exactly three bases long, so an mRNA strand with 60 bases would contain 20 codons. The first codon will encode for methionine (this is called the "start" codon) and the last codon will be a "stop" codon, which does not encode for an amino acid. Thus, an mRNA strand of 60 bases will code for 19 amino acids. Keep in mind, it is possible for a stop codon to be anywhere on the mRNA strand, and when a stop codon reaches the ribosome, translation must stop. For example, if an mRNA strand contained 30 codons, and the 15th were a stop codon, the mRNA would only code for 14 amino acids and then be done. The other 15 codons would go untranslated.

What does reverse transcriptase use from DNA?
Reverse transcriptase use mRNA to form DNA. mRNA
What polypeptide would you expect from a poly-G mRNA that is 30 nucleotides long?
a polypeptide of 10 glycine's
How long is the mRNA that codes for the protein with 250 amino acid?
The coding part of the mRNA would be 750 bases long. However, the mRNA would be much longer than this in real life as there would be both a 3 prime and 5 prime untranslated region. The lenght of the untranslated regions varied depending on the protein in question, the organism it is from and even the location in which it is produced in that organism! In summary, it is impossible to answer this question.
Where is the process of making mRNA from DNA called?
DNA to mRNA is transcription, whereas mRNA to tRNA is translation. The latter part is when proteins are made from ribosomes and instructions carried over by mRNA from the DNA.
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.
