Answer:
Explanation:
Transcription takes place in nucleus in the presence of the enzyme RNA polymerase.
During transcription, the code present in DNA gets transcribed into the code in mRNA. (messenger RNA)
RNA even though is a single stranded shows base pairing.
The pre-mRNA gets created from the DNA.
DNA has two strands, one of these strands acts as coding and another non coding strand.
The DNA shows base pairing with AGTC. [A-Adenine, G- Guanine, T-Thymine and C- Cytosine]
Whereas mRNA base pairing with AGUC. [ U- Uracil ]
Here in mRNA, instead of thymine, uracil gets paired.
According to base pairing of coding strand/sense strand of DNA, complementary bases pairs in 5'---->3' direction in mRNA.
The mRNA created looks exactly like the non-coding strand/sense strand of DNA except instead of thymine, uracil gets replaced.
The pre-RNA undergoes splicing, capping and tailing to form mature mRNA.
Must be placed in the plantae kingdom
only plants use photosynthesis
Answer:
The main dangers worldwide are population growth and resource consumption, climate change and global warming, habitat conversion and urbanisation, invasive alien species, over-exploitation of natural resources and environmental degradation.
Explanation:
Answer:
D. Inhibits the degradation of 2,3-BPG, thereby increasing its concentration in erythrocytes
Explanation:
A pharmaceutical company trying to develop a drug that improves tissue oxygenation by increasing the percentage of oxygen that is released from hemoglobin during its passage through the capillaries of extrapulmonary tissues. This drug, it is hoped, would become a popular doping agent for athletes.This means that the company should try a drug that Inhibits the degradation of 2,3-BPG( 2,3-Bisphosphoglycerate) , thereby increasing its concentration in erythrocytes
While looking at a cell under a microscope, a scientist is able to see a
biological molecule. This molecule is a nucleic acid with double
strands and
<span>
contains the nitrogenous bases adenine, thymine, cytosine, and guanine. Based on this information, the scientist can conclude that </span>"
The nucleic acid is DNA and would be found in the cell’s nucleus."
