Answer:
DNA was discovered in 1869 by Swiss researcher Friedrich Miescher, who was originally trying to study the composition of lymphoid cells (white blood cells). Instead, he isolated a new molecule he called nuclein (DNA with associated proteins) from a cell nucleus.
Explanation:
Answer:
The statement that is correct is that all cells have the same genes, but different genes are active in different cells.
Explanation:
Differentiation or specialization is a function that cells possess and is what allows them to have different types of cells and tissues.
Cell differentiation depends on genetic regulation, a mechanism that determines the specific genes that are expressed in a cell or tissue type.
All cells contain the same DNA, which is organized into chromosomes and contain the genes that determine specific characteristics. <u>There is cell differentiation because some genes can be expressed and others are suppressed, all due to genetic regulation</u>.
The other choices are wrong because:
- <em>The eyes look different from the liver, because they have the same genes, but only some are expressed.
</em>
- <em>Differentiated cells and tissues do not lose their genes.
</em>
- <em>All cells have DNA.</em>
Answer:
Here’s one possible answer:
Pros
Simple images make the process easy to understand.
The model accurately shows that protein synthesis has distinct stages.
Cons
The model doesn’t accurately show nucleotides in DNA and RNA.
The model doesn’t differentiate between the locations of processes. It fails to show which processes occur in the nucleus and which occur on the ribosome.
