Answer:
A. The tails do not interact with the DNA
Explanation:
The acetylation refers to the transfer of the acetyl group from Acetyl-CoA to the N-terminal of the histone protein.
Lysine residues (positively charged amino acid) are present at the end of the N-terminal of the histone protein which is neutralized by the acetyl group.
This loses the compaction between the positively charged histone and the negatively charged DNA and the DNA becomes more relaxed. This relaxed state allows the transcription factors to easily bind the DNA and therefore the DNA becomes transcriptionally active.
Thus, Option-A is correct
Answer:
cells are the smallest unit of life
Explanation:
The first action that the nurse should take is to BATHE THE NEONATE.
Typically, new born are bathe within two to four hours after their birth when their temperature have stabilized. But early or immediate bathing is recommended for the babies of HIV positive mothers in order to reduce blood exposure.
Well... Since 2+1=3 and 3+1=4 that means 3+4=7. Following me here? Good. Let's move on. Now, we take the 7 and multiply it by 4.4 to get 30.8. Now take your 30.8 and divide it by 360 (degrees; that is the circumference of a circle and the Earth is a circle) to get .08555 repeating. Now add them all up, it should look something like this... 2kg+1m+4.4m/s+.08555= ~8.25kgmm/s. Congratulations! You found the answer! It is about 8.25 kgmm/s squared. Good job!
Answer:
The answer is primates, rodents/rabbits, crocodiles and birds.
Explanation:
Cladogram
A cladogram is a diagrammatic epresentation of the evolutionary relationships between organisms that emerged from the same ancestor. Basically, it shows how closely one organism is related to another.
A cladogram differs with a phylogenetic tree in the sense that a cladogram only shows evolutionary relationships between one ancestor and all its descendants. On the other hand, a phylogenetic tree explains relationships between many clades (group of related species)
A cladogram also identifies various evolutionary points or milestones of the development of certain characteristics.
According to this cladogram, the amniotic egg evolved before the emergence of the common ancestor of primates, rodents, crocodiles and birds.
