Answer:
a) phenylalanine
Explanation:
A triplet codon results into a particular amino acid. mRNA is read in 5' to 3' direction during translation. tRNA carrying an amino acid enters the A site first. Then a peptide bond is formed between the new and old amino acid. The polypeptide along with the tRNA moves to P site while the now empty old tRNA moves from P to E site and exits. Hence a tRNA is first in A site followed by P site and then finally E site.
Here, a tRNA with histidine amino acid is present in the P site. From the given sequence, only CAU codon can result into histidine. So if CAU region is present in P site that means that UUU will be present in A site. UUU codes for phenylalanine amino acid so the tRNA entering the A site will carry phenylalanine.
Answer:
Explanation:
They can adapte to fresh water but they can also look for the salt i think
<span>Red blood cells normally have a biconcave shape (picture a donut, but instead of a hole through the centre there's just a downward slope to the centre of the cell). If the cell takes on water, it will increase in size and the sloped areas will start to flatten out. If the cell loses water, it will begin to shrivel. Use these observations and your understanding of osmosis to answer the question!</span>
