Answer: Hydrogen bonds are created between the base pairs in DNA. Adenine pairs with thymine and cytosine pairs with guanine. Adenine and thymine create 2 hydrogen bonds while cytosine and guanine create 3. These bonds are fairly weak so that they can be broken when DNA is replicated (by an enzyme called helicase which unwinds DNA). However despite them being weak they do stabilize DNA's double helix structure as well.
Answer: we can see the nucleus obviosly in the eukaryotic cell
C)homeostasis phenomena of adjusting to environment
Answer:
stem cells
Explanation:
gamete cells are purely reproductive, and chromosome have DNA in them
The antibodies have epitopes that bind to the paratropes present on the antigens. When an antibody is made specifically to target a particular kind of antigen (say A), its epitope will be a structural compliment to the paratrope. When an antibody encounters two different antigens (say A and B) with structurally similar paratropes, it will bind specifically to A and non-specifically to B, as the antibody is not made in response to antigen B. This non-specific binding is referred to as blocking.
