Answer:

is bound to the constant region of the secondary antibody.

Explanation:

Enzyme immunoassays are the techniques used to detect the presence of antigens with the help of antibodies. Each of the antibody molecules has a constant and variable region.

The primary antibodies are added to the wells. The constant region of the secondary antibody is bound to an enzyme while its variable region is free so that it can bind to the specific antigen.

Addition of substrate to the system is followed by visualization and/or evaluation of antigen as the reaction between enzyme and substrate produce some visible changes such as color change.

If a particular strand of DNA is found to be 27% adenine, how much guanine would it contain
Naddika [18.5K]

Answer:

You have 20% of adenine. If you have 20% of adenine than you have 20% of thymine, because the amount of adenine and thymine is equal. 20% plus 20% is 40% of adennine and thymine. From 100% DNA bases subtract 40% and you will get 60%. Then divide this by 2 and you will get 30%. 30% of guanine and 30% of cytosine, because their amounts are equal in the DNA stand.

TEA [102]

The question is incomplete as it misses the options which are:

Cancer cells do not exhibit density dependent inhibition

Cancer cells do not require growth factors

Cancer cells do not exhibit anchorage dependence

Cancer cells ignore typical cell cycle checkpoints

Answer:

The correct answer will be option- Cancer cells do not exhibit anchorage dependence

Explanation:

A cell becomes tumour forming cell or cancerous cell when the cell undergoes some mutation in the DNA which causes uncontrolled cell division without differentiation.

As a result of the mutation, these cancerous cells show various properties which are present in the normal cells nut absent in cancerous cells like the cancerous cells lack the anchorage dependence.

Anchorage dependence is the property of the cells or the group of cells in which the cells maintain their adherence to the other layer of cells to communicate with each other.

Thus, the cancerous cells lack the anchorage dependence
