CAASPP 1/3 Biology Final study

DNA vs RNA

DNA and RNA exists in all living organisms both eukaryotic cells and prokaryotic cells. Eukaryotic cells are meant for plants animals and and fungi; They get a nucleus that the DNA stays in. Prokaryotic cells which is meant for parasites don’t have a nucleus so both DNA and RNA float around in the cytoplasm.

\
A monomer is a building block to a bio molecule. Nucleotides are the monomers to a nucleic acid.

The nucleotides / monomers to a nucleic acid are phosphate, sugar and base (DNA ATGC)

The Bases of DNA is ATGC. A =T G = C.

The Bases of RNA A, U, G, C same goes for the RNA but there is no T

\
When connecting a DNA strand sequence of nucleotides and an RNA strand the RNA won’t have T on its strip.

\
RNA - UCCAG

DNA - AGGTC

\
RNA- UUUAGC

DNA- AAATCG

\
==mRNA tRNA rRNA:==

Transcription come before translation. Transcription is done in the nucleus where DNA calls for messenger RNA to carry a message outside. Translation is next. The messenger RNA goes to rRNA (ribosomal RNA) to have transfer RNA fit together the amino acids to the mRNA.
