Answer:
The best answer to the question: If every gene has a tissue-specific and signal-dependent transcription pattern, how can such a small number of transcriptional regulatory proteins generate a much larger set of transcriptional patterns? Would be:
Because transcriptional regulators, which are the ones responsible for initiating, and stopping, transcription of RNA into protein, often work in pairs, one goes with the other, and thus increase the regulatory capabilities over gene expression so that the genes translated into RNA and then transcribed into aminoacids in protein chains, actually code for the correct protein types.
These regulators will both stand, as appropriate, on a specific gene to promote its transcription, or prevent it, depending on the different signaling mechanisms received.
I think it is the 1st & last answer. When you get a job, or most jobs, they require to to work cooperatively. 2 heads are better than one in trying to find a solution to a problem. Some people are better suited to have jobs that required not as much teamwork, but you have to get the job first.
Answer:
Physical change means that only the form / shape of the substance is changed , not the chemical properties. So here, cutting of paper is a physical change since it's shape is changed but the chemical properties remain the same.
- In the mRNA; A will be complementary to U
- In tRNA; U will be complementary to A
The mutation does not affect the structure of the protein and is called a silent mutation.
<h3>What is a mutation?</h3>
A mutation is a change that occurs in the sequence of nucleotides of a gene.
The mutation that changes the base G in the DNA to A will result in the following corresponding changes in the mRNA and tRNA:
- In the mRNA; A will be complementary to U
- In tRNA; U will be complementary to A
The mutation does not result in any changes since the amino acid coded for by the mRNA has more than one codon coding for it.
This type of mutation is called a silent mutation.
In conclusion, some mutations occurring in genes have no effect on the proteins the gene codes for.
