saw5 [17]

Ans. (4). protein synthesis.

Protein synthesis can be defined as a process that involves formation of polypeptides or proteins by using information present in DNA. It is divided into two steps, transcription and translation.

During transcription, DNA is transcribed into mRNA and information present in DNA is transferred to mRNA as codons. Codons represent triplet of nucleotides and each codon codes for a specific codon.

Translation involves formation of protein, during which amino acids are added to the growing polypeptide chain with the help of codons.

The given diagram represents process of translation. Thus, the correct answer is option (4).

On average, activated yeast cells divide once every 120 minutes; that is, each individual cell divides into two individual cells
astra-53 [7]

Answer:

The correct answer is 4,960,000

Explanation:

If a yeast cell divides into two yeast cells in 120 minutes that means a yeast cell needs 2 hours to get double. So according to the question 2 hours ago a yeast colony consisted of 310,000 cells that means the present colony should have 620,000 cells.

So after six hours from now, this population will divide three times in six hours because the generation time of yeast cell is 2 hour and each time the number of cells will double.

Therefore, in first time the number will increase to 1,240,000(620000*2), the second time the number will increase to 2,480,000(1240000*2) and after final division, the number will be 4,960,000(2480000*2).

Therefore after 6 hours from now, the approximate number of yeast cells will be 4,960,000.
