The chemical structures of the 22 standard amino acids, along with their chemical properties, are described more fully in the article on these proteinogenic amino acids.
Answer:
Because the earth's axis is tilted. It is all about the tilt of the Earth axis.
Explanation:
You find a 10,000,000 year old rock 2,500 km away from the
nearest seafloor spreading center. The plate has been moving since its
formation by (2,500 km)(100,000 cm/1 km)/(10,000,000 yr).so the plat has been
moving equal to 25 cm per year since its formation.
The most accurate response would be between A and D.
Answer:C
Explanation:
During termination of transcription a section of DNA contains about 20 basepair GC nucleotides. This GC rich sequence that marks the end of a gene during transcription.
In the Rho-independent transcription termination mechanisms, the formation hairpin rich in GC nucleotides causes RNA polymerase to stall,
It is difficult for RNA polymerase can to work pass through GC rich hairpin, because GC basepair is made of 3 hydrogen bonds.
This causes the RNA polymerase to stall
