Sam's Blog!



Today in class we went over our homework. Also here is a reminder!- TEST THURSDAY! Study Study Study!!!!
Protin does everything! Ex. If you wear contacts you have to put them in solution to get more protin.




  • DNA Replication- When a cell reproduces, some parts can simply divide.

  • The longest stage in the cell cycle is interphase.

  • A DNA molecule is made up of nucleic acid building blocks called Nitrogen Bases.

  • During replication, the DNA molecule "unzips". The base pairs separate.

  • Protein Synthesis Recall that proteins play an important role in cells and in multicellular organisms.

  • Protein Synthesis is another important process that takes place throughout interphase.

  • At the ribosome, mRNA pairs up with molecules of transfer RNA.

  • Each piece of tRNAbhas three bases and carries a spacific amono acid.

  • Proteins are made in a cell's ribosomes. Protein synthesis involves several stages. First, the genetic information from the nucleus has to be carried to the ribosomes. This is done by a molecule called messenger RNA ( mRNA).
  • Replication
  • RNA uses uracil
  • RNA does not use thymine but DNA does
  • RNA has different backbone then DNA
  • DNA ( DXY ribose)
  • RNA is only a copy
  • DNA is actual instructions
  • RNA is transcription and DNA is replication
  • SIngle is RNA (sugar strand)
  • Double sugar strand is DNA

  1. Thanks Sam! I got my notes sort of messed up, so this helped me.

  2. just wondering if we had to know what interphase was...if so could you explain it a little bit more because I am confused.
