Which statements are true for a protein whose genetic sequence has 11 codons?
slega [8]

Answer:2.)One start codon and one stop codon are used for its synthesis.

3.)The piece of genetic code used for its production contains 11 codons.

Explanation: A codon is a nucleotide sequence on the mRNA that is made up of three nucleotides molecules. A codon is a nucleotide sequence that codes for a specific amino acid. Every amino acid is coded for by at least one codon. Some amino acids are coded for by more than one codon.

During protein synthesis, every protein is synthesized using one start codon and one stop codon. A start codon signals the beginning of translation while the stop codon signals the end of translation. The start codon codes for methionine while the stop codon codes for no amino acid. Therefore, a protein whose genetic sequence has 11 codons is synthesized using a piece of genetic code containing 11 codons.

The beaker in the illustration below contains two solutions of salt with different concentrations (measured by molarity, M). The
skelet666 [1.2K]

Answer:

Option C

Explanation:

Image for the question is attached here

Solution

It is given that the membrane is permeable to both salt and water.  

Thus, water will form region of high concentration to the region having low salt concentration. The same applies to the movement of water molecule.  

As we can see in the image, Side A has higher water concentration and side B has higher salt concentration.  

Thus water will move from side A to side B and Salt will move from side B to side A.

Hence, option C is correct
