Which of the following characterizes the lag phase of the bacterial growth curve?
Zepler [3.9K]

Answer:

Little increase in cell number

Explanation:

There are four distinct phases in the bacterial growth curves that is lag, log, stationary and death phase. The lag phase of the bacterial growth curve is characterized by very little increase in the cell number.

The growth rate of bacteria in the lag phase is slow because the medium is new to the bacterial culture and it requires time for bacteria have to adapt to the new cultural environment and to synthesize enzymes required for substrate utilization.  

After getting adapt in their new environment bacteria starts to grow at an exponential rate. So little increase in cell number characterizes the lag phase.

15. Which of the processes has more than one type of RNA involved?
erastova [34]

Answer:

Translation

Explanation:

Translation is the process by which mRNA is decoded and translated to produce a polypeptide sequence, otherwise known as a protein. This method of synthesizing proteins is directed by the mRNA and accomplished with the help of a ribosome, a large complex of ribosomal RNAs (rRNAs) and proteins. In translation, a cell decodes the mRNA’s genetic message and assembles the brand-new polypeptide chain. Transfer RNA, or tRNA, translates the sequence of codons on the mRNA strand. The main function of tRNA is to transfer a free amino acid from the cytoplasm to a ribosome, where it is attached to the growing polypeptide chain. tRNAs continue to add amino acids to the growing end of the polypeptide chain until they reach a stop codon on the mRNA. The ribosome then releases the completed protein into the cell.
