Answer: e. prokaryotic cells lack nuclei.
Explanation: Prokaryotes are unicellular (single-cell) organisms that lack well developed cell internal membrane-bound structures or organelles. They do not have a nucleus but generally, they have a single chromosome that possess a double-stranded DNA located in an area of the cell called the nucleoid. Most prokaryotes have a cell wall outside the plasma membrane.
Purines: adenine and guanine
The provided question is incomplete as it lacks the image required to identify the, however the correct image is attached:
Answer:
B is protein
C is the process of translation
Explanation:
The given image is a flow chart representation of the process of the protein synthesis from the DNA molecule by a two-step process that is combinedly known as the central dogma.
The first step is a transcription in which an RNA molecule (mRNA) is synthesized from the DNA molecule in organism nucleus (in eukaryotes only). The second step is to making a polypeptide chain of amino acid with help of rRNA, tRNA, and mRNA, this process is known as translation and represented in the image as C and B is the protein that formed.
Thus, the correct answer is - B is protein
C is the process of translation
