Answer:
The correct answer is option d) "Silencer".
Explanation:
Gene silencing is the regulation of a gene expression that results in avoiding the expression of a gene during a certain period of time. A silencer is a DNA sequence that produces gene silencing. In this example the researcher founds that a gene is not longer regulated in all cells and the gene is still transcribed and translated into protein. The mutation responsible of this it is likely to be occurring in a silencer, avoiding gene silencing of the studied gene in all cells.
Answer:
<em>The correct option is A. Nucleotide sequence, human, hemoglobin</em>
Explanation:
If the segment of the DNA for the human gene is known then it will be very easy to find the gene on a database. The tags which should be used will be the nucleotide sequence, where the known sequence shall be mentioned.
Then we will choose the tag for the organism which is humans in this case. Then we will select the tag for the protein which is made by the nucleotide sequence, which is protein in this case. Hence, option A is the correct answer.
DNA polymerase is an enzyme with a specific active site complementary to the 3' OH end of the DNA strand in terms of charge, size, orientation and shape thus can only bind to 3' end and cannot bind to 5' end for replication to occur
The value which is being measured in the columns labeled "Fraction remaining" and "Percentage remaining" is: D. amount of material that has not decayed.
<h3>What is a radioactive decay?</h3>
A radioactive decay can be defined as a radioactive process in which an unstable atomic nucleus undergoes a spontaneous transformation into one or more different atomic nuclei and simultaneously emits radiation, accompanied with a loss of energy.
<h3>The types of
radioactive decay.</h3>
In Science, there are three main types of radioactive decay and these include the following:
- Alpha decay
- Beta decay
- Gamma decay
Based on the information provided in the table (see attachment), we can reasonably infer and logically deduce that the value which is being measured in the columns labeled "Fraction remaining" and "Percentage remaining" is the amount of material that has not decayed.
