Answer:
False
Explanation:
A double-helical DNA molecule consists of two DNA strands. A DNA strand has free 5' phosphate at one end and a free hydroxyl group (OH) at its 3' end. A DNA double helix is said to be antiparallel since each end of the double helix has an exposed 5' phosphate on one strand and a free 3' hydroxyl group (OH) on the other. This means that the two DNA strands run in opposite directions. A phosphate group is always esterified to the 5' carbon of the pentose sugar; never at its 3' end.
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
Answer: Options A, B, C, D at correct
Explanation:
Cnidarians are a branch of invertebrates characterised by by a radially symmetric body including a saclike internal cavity and nematocysts; stinging structures that aids in feeding. They are also known as coelentrates. They are diploblastic (2 body layer). They also reproduce asexually by various mean including budding. Example include sea anemones, hydra, corals, jellyfish etc
That would be peptide bonds
An animal cell lacking carbohydrates on the external surface of its plasma membrane would likely be impaired in CELL TO CELL RECOGNITION.
Carbohydrates have diverse functions, one of their functions is that they serve as a recognition signal at the surface of cells.
Carbohydrates located on the surface of cells enable cells to recognize and communicate with one another.
