Lisa and Vinay are looking under a microscope at animal cells. They see an organelle that they think is the endoplasmic reticulum. Which statement would support their
idea?

•the organelle contains DNA
•Othey observed ribosomes on the structure

The correct answer is - they observed ribosomes on the structure.

Explanation:

The endoplasmic reticulum is the cellular organ eukaryotic organisms, that is tubular in shape and present in the cytoplasm that plays role in protein folding and part of the transport system of the cell. It has two subunits smooth endoplasmic reticulum and rough endoplasmic reticulum.

Rough endoplasmic reticulum has ribosome molecules present on the surface of the structure that is sending the protein to ER where folding of the protein and transport of the protein.

ans.

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.'

i think the answer is c hope this
