Answer:
B) You measure the quantity of the appropriate pre-mRNA in various cell types and find they are all the same.
Explanation:
In the above scenario, we are using the control gene and we should know about the control gene is that its expression is either at transcription level or at translation level. For this situation we should examine the pre-mRNA stage of control gene in various cells because it is control gene so it should be present in various cells.
So, the best practice is to quantify the pre-mRNA level of gene then we can effectively solve the experimental problem and find the gene expression either it is at transcription or translation level.
There are exactly 24 chromosomes in a girl cell and 24 in a boy cell.
Answer:
Yes, swollen lymph nodes are more common than some might think.
Explanation:
The medical terms for swollen lymph nodes are adenopathy or lymphadenopathy.
Lymph nodes play a vital role in fighting off sickness in the body. They act as a filter, trapping bacteria and viruses before they can spread too far.
Lymph nodes <em>typically</em> swell up as a response to bacteria or viruses. Though cancer can be a factor in swelling, it is very rare. Most commonly they are felt right below the corner of the jaw, in the neck. Yet, they are not only in the neck; they are all throughout the body. When they are swollen, they might feel tender or even painful.
Answer:
The correct answer is -
1. protein synthesis or central dogma
2. leads to changes in the structure by changing in the codes which results in a decrease or loss of function.
Explanation:
1, Protein is made from the information coded in DNA base sequences by the two process protein synthesis that is also called central dogma. The two-process involve in this are transcription involves encoding the information present in DNA by mRNA molecule that codes the information in complementary sequence to DNA. which is then moved out of the nucleus and perform the translation with help of tRNA and ribosome to code the amino acid with help of triplet codes present in mRNA. These amino acids chain are called proteins.
2. Mutations can lead to change in the base sequences or deletion of the base which affects the structure of the protein and also leads to changes in an encoded protein or to a decrease or complete loss in its function or expression. Mutation can damage the cell or organism as it affects the gene expression of all cells of organisms.
