The following table represents the number of bacteria, algae, viruses, and fungi in a pond at different temperatures. All values represent the number of millions of bacteria, algae, fungi, and viruses in a single liter of water.

1. According to the information provided in the table, the number of which of the following substances is constant after a pond reaches a temperature of about 20 degrees?A.BacteriaB. FungiC. AlgaeD. Virus

2. If the number of bacteria continued to increase at the same rate as the pond continued to warm, what would the measurement be at 30 degrees?A. 400B. 640C. 860D. 12703. Based on the information presented, the number of which of the following substances is not determined by the pond's temperature?A. BacteriaB. FungiC. AlgaeD. Viruses

CENTRAL DOGMAHOW DNA BECOMES YOU

CENTRAL DOGMA

The idea that DNA is a code that dictates who you are.

TRANSCRIPTION

DNA gets rewritten into RNA

DNA Strand

RNA Strand

RNA

Ribonucleic Acid

Single Strand

Has Uracil instead of Thymine

Nitrogenous Bases: A, C, U, G

TRANSCRIPTION

-Occurs in Nucleus

-RNA Polymerase makes the RNA

TRANSCRIPTION PRACTICE

DNA Strand: A T G G T C C

RNA Strand:

RNA:A – UC – G

TRANSLATION

“Translates” RNA sequences into amino-acid chains

Amino Acid Chains make up proteinsProtein Chain

RNA

TRANSLATING

Split RNA sequence into sets of three bases (triplet-codons)

SNORK ACTIVITY

You will make your own SNORK based on the genetic code given

1.Transcribe the sequence into RNA

2.Translate the sequence into an amino-acid chain

3.Find what A.A. sequence codes for what trait

Graph this data. Use what ever graph you think to be the correct one.
