<span>The main difference between DNA and RNA is that DNA contains double-stranded molecules and RNA contains single-stranded molecules. DNA stands for deoxyribonucleic acid and RNA stands for ribonucleic acid. Both DNA and RNA carry genetic information, but there are a few major differences between them. DNA consists of the sugar deoxyribose, and RNA contains the sugar ribose. Ribose contains one more -OH group than deoxyribose. Another difference is that DNA is stable under alkaline conditions while RNA is not stable.</span>
When cell over divide they cause a sickness or cancer
They eat by a process called phagocytosis whenn entire food is digested
The process of converting the genetic message from DNA into RNA is called transcription.
Transcription is the phase of gene expression in which a certain part of DNA is copied into RNA. Transcription is carried out by the enzyme RNA polymerase which joins nucleotides to produce an RNA strand and uses a DNA strand as a template. The three stages involved in transcription are initiation, elongation, and termination.
