likoan [24]

The best answer is C.

Chloroplasts are not found in all eukaryotic cells but only in plant cells. Animal cells are eukaryotic in nature but animals do not have chloroplasts in their cells because they do not engage in photosynthesis.

Photosynthesis is the process by which plants make their own food. Chloroplasts  contain chlorophyll which is essential in t trapping sunlight from which supplies the energy for photosynthesis. 

Animals do not make their own food like plants but eat ready made food so their cells  lack mechanisms for food manufacture.

A segment of a gene contains 27 nucleotides, none of which include stop or start codons. How many amino acids does this segment
blondinia [14]

If none of the nucleotides includes stop or start codons when a segment of a gene contains 27 nucleotides there will be 81 amino acids in this segment code.

Answer: Option B

<u>Explanation:</u>

Codon is a nucleotides within messenger RNA. A stop or start codon is a nucleotide triplet which signals protein termination. Start codons initiate to start translation while the stop codon initiates termination.

The genetic codes are the sequence for nucleotide that codes for amino acids. A segment containing 27 nucleotides multiplied by 3 gives 81 amino acids. Every nucleotide in an mRNA are read “three at a time”. Hence this segment codes for 81 amino acids.
