Free DNA RNA Amino acid
(production of mRNA from DNA) SiRNA: 1. An enzymes cuts up a piece of double stranded mRNA. 2. This makes little double stranded fragements‚ called SiRNA. 3. One strand of the SiRNA binds with a enzyme. 4. The enzyme is brought to the mRNA‚ due to the free bases of the SiRNA binding to a complimentary region on the mRNA. 5. The enzyme cuts of the mRNA into smaller fragments‚ seperating the sequence of triplet codons‚ meaning not all of the amino acids needed for the proteins

1. If one strand of a DNA double helix has the sequence GTCCAT‚ what is the sequence of the other strand? a. ACTTGC b. CUGGTU c. CAGGTA d. CAGGUA e. TGAACG 2. If a strand of DNA has the sequence AAGCTC‚ transcription will result in a(n) ______. a. single DNA strand with the sequence TTCGAG b. single RNA strand with the sequence TTCGAG c. DNA double helix with the sequence AAGCTC for one strand and TTCGAG for the complementary strand d. single

provide info for protein synthesis • Enzymes Involved in order – o Single Strand o Helicases – disrupt hydrogen bonds that hold two strands together. o Primase (RNA polymerase) – Provides a starting place for DNA polymerase III‚ synthesizes short strands of RNA (primers) that are complimentary to DNA o DNA Polymerase III - synthesizes the new strands of dna complimentary to the original. Must have a template to start‚ start adding nucleotides to the 3’ end

for functional products Base pairs: always occur in a specific way – A(adenine) always pairs with T(thymine) and C(cytosine) always pairs with (G)guanine. Because of this specific base pairing‚ the base sequence of one DNA strand determines the base sequence of the other strand. Genetic code: the set of rules that determine how a nucleotide sequence is converted into the amino acid sequence of a protein Genotype: an organism’s genetic makeup‚ the info that codes for all the particular characteristics

Double Helix Two DNA strands form a helical spiral‚ winding around a helix axis in a right-handed spiral. The two polynucleotide chains run in opposite directions. The sugar-phosphate backbones of the two DNA strands wind around the helix axis like the railing of a spiral staircase. The Backbone DNA is in the form of a double helix. This means that two helices‚ or sides‚ twist around a center. The sides of the double helix are referred to as the backbone of the DNA strand. They are made up of

eukaryotes‚ transcription factors control gene expression by binding DNA sequences in the regulatory regions. Cell proteins regulate gene expression. RNA contains the sugar ribose and the nitrogenous base uracil instead of thymine. It is usually a single strand. mRNA molecules are made using DNA as a template.

blood. A person can only have this disease if both parents are carriers and they receive two recessive alleles. There are five effects of the disease at different levels. At the DNA level the mutation causes the sequence to be coded GTG‚ CAC instead of GAG‚ CTC which results in a mutant protein. At the protein level the hemoglobin clump together which makes it hard for it to travel through arteries and vessels. At the cellular level the blood cell because “sickle shaped” due to the lack of oxygen

History Capital Gains Tax (CGT) was introduced on the 20th September 1985‚ prior to which there was no formal CGT. Any capital gain before this date is not subject to CGT. ▪ Between 1985 – 1998: the relevant legislation was under PTIII‚ subdivision A of the ITAA36 (7-020) The statutory provisions in operations between 1985-1998‚ PtIIIA ITAA36‚ was criticised for being too complex‚ having unfair outcomes‚ and for distorting commercial decisions.
