<span>it was molecular structure of DNA this was appeared 1n April 1953 Watson and Crick presented the structure of DNA- Helix.it carried the genetic information. the DNA Molecule shaped in twisted ladder.franklin produced an X- ray photograph.
DNA structure is made of molecules called nucleotide. Watson and crick also work on 3-D structure of DNA. this mark the history in molecular biology to understanding the genes control and genetic information.they also work on cell.they use stick and ball to understand to test their idea.</span>
Answer:
How do punnet squares allow you to predict how traits are passed from one generation to the next?
This is simply achieved by crossing which enable each gene of both parents to be paired with one another
Explanation:
Answer:
<em>The correct option is C) Water is repelled by the hydrophobic tails of the phospholipid.</em>
Explanation:
The cell membrane is made up of phospholipids. The phosphates make up the head and are hydrophilic. The lipids make up the tail and re hydrophobic. The cell membrane is double layered with the heads pointing outwards and the tails embedded inwards. As lipids do not dissolve in water, hence the cell membrane is partially permeable for water. The tails made up of lipids are hydrophobic and hence repel water.
