Answer:
The correct answer is B the extra chromosome has typically undergone significant rearrangements.
Explanation:
Trisomy is a type of aneuploidy which is characterized by the presence or occurance of an extra copy of a particular chromosome.As a result the chromosomes in which the trisomy is occurring contain 3 arms instead of 2. Trisomy occur due to non disjunction of a particular chromosome during meiosis.
As a result a second copy of chromosome is present inside the cell containing that abnormal chromosome.If the same thing occur in the cell of gamet undergoing fertilization then there is a high chance that the embryo will carry that extra chromosome.
In case of humans Trisomy result in the rearrangement extra chromosome which ultimately give rise to
1 Trisomy 18 occur due to extra copy of chromosome no 18
2 Trisomy 13 occur due to extra copy of chromosome no 13
3 Trsomy 21 occur due to extra copy of chromosome no 21 which is also called down syndrome.
Answer:
a) because after the cleavage of the phosphate groups, the phosphate at the 5´carbon atom is ready to bind the oxigen from the OH- in 3´carbon en the incoming nucleotide
b) The DNA ligase will need an energy source because after removing the RNA, the 5´carbon will not have the three phosphates to be cleaved so that the energy of those unions can be used to catalize the new union
Answer:
The use of genetic engineering in developing disease-resistant plants. The techniques of genetic engineering can be used to manipulate the genetic material of a cell in order to produce a new characteristic in an organism.
Answer:
YASS BRO STRANGER THINGS IS THE BEST
Explanation:
For the answer to the question above, <span>Lipid Rafts are subdomains of the plasma membrane it contains high concentrations of cholesterol and glycosphingolipids. It exists as distinct liquid-ordered regions of the membrane that are resistant to extraction with non-ionic detergents.
So the statement above is <u>"NOT TRUE OR FALSE" </u>
