Which Is The Correct Sequence Of Molecules As A Gene Goes From Coded Information In The Nucleus To The Product The Cell Wants To Make?
The correct sequence of molecules as a gene goes from coded information in the nucleus to the desired product involves DNA, mRNA, and proteins. First, the gene in the DNA is transcribed into messenger RNA (mRNA) in the nucleus. The mRNA then exits the nucleus and is translated into a protein by ribosomes in the cytoplasm. Finally, the protein carries out its specific function in the cell.
What is the name of the process of making mRNA copt of a gene?
The process of making an mRNA copy of a gene is called transcription. During transcription, the DNA of the gene is used as a template to synthesize a complementary mRNA molecule. This mRNA molecule carries the genetic information from the gene to the ribosomes for protein synthesis.
What mechanisms of gene regulation operates after mRNA transcription but before translation of mRNA into protein?
There are two mechanisms as related to above. Firstly, the removal of All Introns occurs - via the Spliceosome -, and then a "poly AAAAAAA" tail is attached to the [edited] mRna transcript just before its export to the cytoplasmic Ribosomes.
What is the stop codon in most molecules of mRNA?
stop codon on mRNA
How does the process of RNA interference work?
Certain small RNA molecules fold into loops. The Dicer enzyme cuts them into microRNA (miRNA). The strands then separate. An miRNA piece attaches to a cluster of proteins to form a silencing complex. The silencing complex binds to and destroys an mRNA molecule that contains a base sequence complementary to the miRNA. In this way, it blocks gene expression.
In what part of the cell will the pre-mRNA be edited?
Transcription. This process is when the mRNA is made, edited, then sent out to be translated.

Where does the transcription of mRNA begin in the process of gene expression?
The transcription of mRNA begins at the promoter region of a gene during the process of gene expression.
What is produced when gene transcription occurs?
During gene transcription, an RNA molecule is produced by copying the DNA sequence of a gene. This RNA molecule can be further processed into messenger RNA (mRNA), transfer RNA (tRNA), ribosomal RNA (rRNA), or other types of functional RNA molecules that carry out various cellular functions.

Small pieces of DNA that is edited out of the mRNA message before it is expreeed?
Small pieces of DNA that is edited out of the mRNA message before it is generated is a intron. It is removed by the RNA splicing.
Can Shrna development be used in medical reasearch?
Shrna development may of course be used in medical research. The molecules inhibit gene expression in the DNA. They cause the destruction of the mRNA molecules.
What happens to mRNA after protein synthesis?
Some stays around for a while so many polypeptide chains can be run from it, while other mRNA is degraded in the cytosol almost immediately by enzymes designed for the task. Depends on how much protein product is needed in the representation of the particular mRNA.
What is the new mRNA stand produced by this mutated gene?
The specific sequence of the new mRNA strand produced by a mutated gene will depend on the nature of the mutation. Mutations can cause changes in the coding region of the gene, leading to alterations in the mRNA sequence and potentially affecting the resulting protein or gene function. Further analysis and sequencing of the mutated gene would be required to determine the exact mRNA sequence.
Which of these is a type of post-transcriptional regulation of gene expression?
Post-transcriptional regulation of gene expression can refer to the life of mRNA. You see, mRNA is transcribed into a protein in the cytoplasm, and if the mRNA only stays in the cytoplasm for a short period of time, then only some of the enzymes coded for on the strand can be created. So if the mRNA is programmed to die early, then only some of the proteins will be produced and only some genes will be expressed. It can also refer to the excision of introns and sometimes exons. pre-mRNA is usually edited by proteins to take out the introns, which are basically useless gene sequences (sometimes called junk DNA). Then the mRNA goes on to express the genes it codes for. But if the proteins take out introns and ALSO some exons, then some genes will be removed and not be expressed. This is another type of post-transcriptional gene regulation. Hope this helped!
What is the stop codon in most molecules of mRNA?
stop codon on mRNA
