Answer:
cAMP dependent pathway is important for processing of life.
Explanation:
cAMP pathway is also called as adenynyl cyclase pathway.
This mechanism requires different steps like-
- G protein coupled receptor is a integral protein that is activated by different external stimuli which binds with the specific ligand.
- Extracellular ligand causes activation of GPCR which in turn is responsible for conformational change in the receptor and allows it to bind with the intracellular heterotrimeric G protein complex.
- The Gα stimulate G protein complex to exchange GDP for GTP and then the complex is released.
- Activated Gα binds with adenylate cyclase and catalyzes ATP to form cyclic AMP.
- Activation of cAMP leads to the activation of nucleotide gated ion channel, and PKa(Protein kinase A) which is also called as cAMP dependent enzyme.
- Once, PKA is activated,it causes phospholylation of other proteins like AMPA receptor,transcription factors which regulate gene expression, and convert glycogen into glucose.
Adenine pairs with thymine. They form complementary pairs withone another during replication of the parent strand, forming the complement strand. If thymine is present for 30% of the bases, then its complement, adenine, will also be present in 30% of the bases.
The answer is B. this has to be 20 characters long.
Answer:
Explanation:
The tar located in the La Brea tar pits is today a fossil fuel that began its formation many hundreds of millions of years ago from the bodies of marine organisms. During the last ice age that ended a few tens of thousands of years ago, some animals got trapped in the tar and left their bones behind. They are not something that created it but only got trapped in preexisting tar.
There are multiple differences between RNA and DNA
1. DNA has two strands whereas RNA has one
2. DNA has deoxyribose sugar while RNA contains ribose sugar
3. DNA contains thymine instead of RNA's uracil
4. DNA cannot leave the nucleus and RNA can (mRNA)
