Answer:
Circulation and Digestion
The muscular system and the circulatory system work with the small intestine. The muscular system helps the small intestine break down food. The circulatory system works with the small intestine and gets nutrients to the rest of the body.
Answer:
Is C
Explanation:
In translation, the cell uses the genetic information contained in mRNA to make the proteins that
carry out the cell’s work. The cell translates the code contained in the mRNA into a new
language, the language of proteins, based on amino acids. Other types of RNA, such as transfer
R
In this section, you will be introduced to the components involved in the process of protein
synthesis, called translation. This process requires a protein/RNA complex called the ribosome
Answer: invivo
A person has a genetic condition that affects his ability to produce melatonin, which is a hormone that is produced in the brain and tells the body it’s time to sleep. To correctly diagnose this disease, the doctor must collect cell samples invivo to analyze his DNA.
Explanation:
Invivo refers to the within the living organism. Since DNA is located inside the nucleus of brain cells, and it regulate gene expression; then the doctor must analyze the genetic information contained in the DNA of brain cells of the person having trouble with secreting melatonin ( the sleep/wake hormone), if any alteration has occurred.
Thus, based on the location of DNA, the doctor must collect cell samples invivo for analysis
Hemophilia: a genetic condition where blood clotting is slowed by the lack of the clotting factor . Only boys can get this!
The appropriate sequence of steps involved in recombinant DNA technology are as under :-
1) Selected gene is isolated.
2) Restriction enzymes cut DNA into fragments.
3) Fragments of DNA are inserted into a vector.
4) Vector and recombinant DNA multiply.
5) Recombinant DNA is inserted into host.
In the very first step, the desired gene/genetic material for cloning is isolated from the cell. To do this the cell is lysed. Cells can be lysed by sonication or using chemicals like detergents.
In the second step, isolated DNA/gene is cut with the help pf biological scalpels known as restriction enzymes. The vector (usually it is a plasmid) is also cut down using restriction enzymes.
In the third step, the fragment of the restriction digested DNA (gene) and the vector are ligated together.
In the fourth step, this vector in which desired gene has been incorporated is cloned to generate various copies.
In the last step, this recombinant DNA is inserted into a host cell where is expressed i.e. in host cell this desired gene produces its product (protein).
