Answer:
D variations in individuals are not heritable
Explanation:
Genetic variation in individuals is what drives evolution. In a population of individuals in an environment, with the adequate resources, overpopulation can occur. However, resources are usually a limiting factor for population growth: there is not sufficient food/shelter etc. for everyone to survive.
Some individuals are better suited to success in the environment. This is because of random variation in their DNA that has arisen that give them a selective advantage. This allows them to thrive, take advantage of the limited resources over other members of the population, and be more likely to survive to reproductive age. This is natural selection.
Because this variation is genetic (in the DNA), they can then pass it on to their offspring. Over time, this leads to evolution over time.
Answer:
mRNA is transcribed from DNA.
The nucleotides in mRNA code for amino acids.
tRNA translates the mRNA sequence into an amino acid sequence so proteins can be made.
Explanation: FOR REAL THE FACTS
Answer:
nucleosomes = 1.65 x 10^6
H2a = 3.3 x 10^6 molecules
H2b = 3.3 x 10^6 molecules
H3 = 3.3 x 10^6 molecules
H4 = 3.3 x 10^6 molecules
Explanation:
It was mentioned in the book Principles of Genetics By D. Peter Snustad, Michael J. Simmons that in the nucleus of <em>D. melanogaster </em>there will be 1.65 x 10^6 nucleosomes and 3.3 x 10^6 molecules of every type of histone i.e. H2a, H2b, H3, and H4 present in it.
