What is the function of the structure identified by the red arrow?

genetic information

mobility

food capture

protection

The correct answer would be genetic information.

The organelle marked with a red arrow is a nucleus.

The nucleus of the cell refers to the control center of the cell as it contains the genetic material of the cell.

The main function of the nucleus is to control all the biological activity of the cell and helps in transferring the genetic information from parents to the offspring.

dna fingerprinting is defined as a process that determines the dna characteristics of an individual. these dna characteristics are unique among individuals as their fingerprints, so it is known as dna fingerprinting.

steps of dna fingerprinting includes extraction of dna from sample, amplification of dna, restriction digestion of amplified dna, and then analysis of dna by gel electrophoresis, respectively.

thus, the next step performed by the scientist is 'to cut the amplified dna (obtained by polymerase chain reaction) by restriction enzymes that cleave the dna into fragments and their analysis.'

only about ten percent of the energy at one trophic level is passed on to organisms at the next trophic level. the remainder of the energy is used in life processes or lost as heat.
