Answer:
Euglenoids lack a Cell wall
Explanation:
Euglena is a unicellular photosynthetic protista that can be found in both salt water and fresh water. As Euglena has chloroplasts they can produce their own food through photosynthesis. For their movement in water they have specialized structure called flagella. Near Flagella another pigmented spot exist called eyespot. Eyespot helps euglena to detect sunlight. Euglenoids lack cell wall so they have more flexibility for movement.

Answer:
Accuracy of DNA and mRNA codes are assured through proofreading and complimentary base pairing.
Explanation:
DNA replication is the process of producing two identical daughters DNA molecules from a parent DNA molecule. During the process of replication, the accuracy of the DNA is usually ensured by mean of proofreading, which is carried out by DNA polymerase enzyme. This enzyme accurately copy the genes in the parent molecule into the daughter molecules.
During the transcription stage of protein synthesis, the transcription process is proofread by RNA polymerase, which catalyzed the process of producing mRNA. During the translation process, the accuracy of the mRNA codes are ensure by mean of complimentary pairing of bases; adenine bind to uracil while guanine bind to cytosine.
