Answer:
Yes.
Explanation:
Yes, DNA is formed from three main components comprise of deoxyribose sugar, phosphate group, and a nitrogen- containing base. This DNA molecule have a genetic information about the organism's form and structure. DNA is made of blocks of nucleotide and that nucleotide is formed from deoxyribose sugar, phosphate group, and a nitrogen- containing base.
Answer:
DNA extraction is the first step in the genetic engineering process. In order to work with DNA, scientists must extract it from the desired organism.
Answer:
True
Explanation:
The embryonic development of fertilized egg includes cleavage, blastulation, implantation, gastrulation and organogenesis.
Cleavage division divides the zygote into blastomeres. First cleavage division result in two blastomeres, second cleavage division results in a transient three cell stage. Third cleavage division forms 8 blastomere. These result in the formation of a sold ball of cells called morula. Morula is 16 cell stage and it descends towards the uterus in 4-6 days. As the morula enters the uterus, it gets a rich supply of nutrients. Trophoblast cells are formed which secrete a fluid into the interior creating a cavity called blastocoel. The inner cell mass now comes to lie on one side as embryonal knob. With the formation of blastocoel, morula is converted into blastula which is called blastocyst in mammals.
Answer:
No, in molecular cloning cutting mistakes can lead to in correct ligation
C) No, because cutting mistakes could lead to incorrect cloning.
Explanation:
in molecular cloning, if you want to insert a specific gene of interest in to specific vector, the selection of enzyme and strategy before that is very important. The restriction enzyme should be selected which restrict at the desired location in the cloning sites. Any mistake in these selection or undesirable mutation mistakes can lead to in correct or unsuccessful cloning results.
I believe the answer is answer D- Nuclear decay rates are constant.
~ Good luck!
