I would go with the second one cuz
DNA<span> and RNA </span>consists<span> of nucleic acid </span>chains<span> called nucleotides. Nucleotides are </span>composed<span> of three units: base, sugar (monosaccharide) and phosphate. Bases are found in both </span>DNA<span> and RNA. </span>
Answer:
- Only fMet-tRNA(fMet) can bind first to the P site in the ribosome. ( A )
- There are more than one tRNA with the 5' CAU 3' anticodon. ( B )
- The N-formyl group attached to methionine prevents fMet from entering interior positions in a polypeptide. ( D )
Explanation:
The statements that explains how N--formyl methionine (fMet) is only associated with the 5' AUG initiation codon and not with internal AUG codons, given that methionine in both cases in encoded by an AUG in the mRNA are :
Only fMet-tRNA(fMet) can bind first to the P site in the ribosome. ( A )
There are more than one tRNA with the 5' CAU 3' anticodon. ( B )
The N-formyl group attached to methionine prevents fMet from entering interior positions in a polypeptide. ( D )
While statement C is wrong.
Tropical rain forest
These area adaptations for the environment specially in the tropical rain forest. The leaves are green and large to maximize their surface for exposure to sun. These will provide better production of food. Stoma on the lower surface of the leaf indicates that the plant us adapted to regulate the amount of water in the leaf. It helps to prevent to much water and also inhibits to much transpiration of eater. Not all plants have these kind of feature. Plants usually adapt to the envitonment to survive.
