Answer:
Catabolic reactions are exergonic.
Explanation:
Exothermic reactions are catabolic, that is, they catalyze molecules, disintegrate them to be able to release energy to the environment that surrounds them and that is how they release or yield to the environment.
<u>Answer:</u>
All cells have same genes, but different genes are active in different cells
<u>Explanation:</u>
Most living organisms are made up of different kinds of cells specialize in performing various functions like nerve cells perform different functions than blood cells. But all the cells are composed of same set of genetic information.
Since biochemical function is found out mainly by some specific enzymes, different sets of genes must be turned on and off in the various cell types to perform different functions. This is how cells differentiate for different functional capabilities.
Answer:
Ulna
Explanation:
The humerus is the long bone in the upper arm. It is located between the elbow joint and the shoulder. At the elbow, it connects primarily to the ulna.
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.
