C and d I think hope this helps I’m sorry if I’m wrong
In Oregon there are lots of winding hills and in Virginia there are just mountains
1.) DNA → RNA use chargaffs base pairing rules
2.) translate the mRNA <span>→</span> protein using the map of codons
One is drift netting. These nets are indiscriminate and also
catch, injure and kill fishes that are not intended to be caught. This, therefore, greatly affects the marine ecosystem.
Second is over-fishing. This reduces the fish population to a
point where they are unable to regenerate and hence predisposes/ condemning them
to extinction
Third is the destruction of marine ecosystem, deliberately,
to clear an obstacle or pave the way for fishing lines. This damages the habits
hence affecting the ecosystem from primary producers and up the food chain.
Answer:
By central dogma, we know that primary structure of the protein is synthesized on the basis of nucleotide sequence of the DNA.
First, the nucleotide sequence is decoded into mRNA which then provides the codon sequence which finally decide the sequence of amino acids in any polypeptide chains.
This amino acid sequence plays an important role in determining the inter and intra polypeptide chain interactions which determine the shape of the protein.
The shape or three dimensional structure of a protein is very important for its proper functioning.
Now, change in nucleotide sequence of the DNA can alter the amino acid sequence of the polypeptide chain which may alter the interactions required for proper folding of the protein. Thus it can result into the formation of mal-functional or non-functional protein.
For example, change in only one nucleotide in DNA leads to the development of sickle cell anemia due to the change in the shape of protein.
