DNA stands for deoxyribonucleic acid and is the carrier molecule for hereditary genetic information.
The DNA molecule is double-stranded, consisting of two complementary polynucleic chains which are antiparallel-facing and which are wound in a double helix (helical form). These two chains are bound by hydrogen bonds between each pair of nucleotides (between guanine and cytosine there are three hydrogen bonds and between adenine and thymine there are two hydrogen bonds). and since the DNA is condensed in the form of chromatin, it also helps to keep this double-stranded structure.

The process of translation in prokaryotes can occur faster than in eukaryotes because
Nimfa-mama [501]

Answer:

Transcription and translation occur simultaneously in prokaryotes.

Explanation:

Prokaryotes lack membrane-bound organelles and therefore, do not have a nucleus. Transcription and translation occur in the cytoplasm. As soon as the required length of mRNA is being formed, ribosomes join it and start the process of translation. Prokaryotic genes lack introns. The primary transcript formed by transcription in prokaryotes does not undergo splicing.

On the other hand, the process of transcription occurs in the nucleus in eukaryotes while translation occurs in the cytoplasm. The primary transcript formed by transcription in eukaryotes undergoes modifications to remove introns and to add a poly-A tail and 5' cap. Post-transcriptional modifications and spatial separation of two processes in eukaryotes result in slower translation than prokaryotes.
