Answer:
They lack a nucleus, but they do have ribosomes.
Explanation:
Prokaryotes are unicellular organisms that lack organelles or other internal membrane-bound structures. Therefore, they do not have a nucleus, but, instead, generally have a single chromosome: a piece of circular, double-stranded DNA located in an area of the cell called the nucleoid.
Answer:
The genetic information in DNA is carried to the cytoplasmic protein-manufacturing centers in form of mRNA.
Explanation:
The process of transcription forms RNA using the DNA template strand thereby copying the genetic information of DNA into the nucleotide sequence of mRNA.
The mRNA leaves the nucleus and enters the cytoplasm to join ribosomes. The nucleotide sequence of mRNA is read in the form of triplet codons to specify the amino acid sequence of the proteins.
In this way, mRNA serves as a carrier of the genetic information in DNA.
Because there's such thing as good bacteria.
Animals' DNA will adapt to the changes, and the ones that inhabited the current ecosystem will mostly die off.
