- What was the hypothesis that illustrated that every gene codes for a protein or polypeptide?
- What do the roman numerals on the left side of the chart represent?
- What do the lines coming off the horizontal line represent?
- Proofreading ability of DNA polymerase enzymes is due to
- True or False DNA polymerase cannot initiate DNA strand synthesis on their own
- True or False Bacteria have multiple origins of replication while eukaryotes just have 1
- Two DNA strands are _____ parallel
- One copy of pol III synthesizes one daughter strandcontinuously in the same direction as fork progression. This is the _______. The other copy elongates the cell discontinuously in the opposing direction of the fork in short segments. This is called _______.
- ____ Hydrogen bonds form between A and T _____ Hydrogen bonds form between C and G
- DNA _____ seals up any gaps among the resulting DNA segments
- Deoxynucleotide ________ are part of the polynucleotide chain where Deoxynucleotide _________ are not
- What do we use in order to find amino acids in gene sequence?
- Start and stop codons tell the ribosome and mRNA when to start building a protein and when to stop. Met (methionine) usually falls off and has no functionality in the actual protein.
- Phosphate (circle), sugar (pentagon, always in middle), nitrogen base (rectangle or hexagon/pentagon)
- a double ringed molecule (purine: AG) is paired with a single ringed molecule (pyrimidine: TC)
- Chromosomes contain several genes and during transcription only one gene is transcribed at a time, so this is only a small part of the chromosome.
- AT and CG base pairs, hydrogen bonds (between pairs), phosphates, sugars (always connect to bases)
- DNA: double helix, stays in nucleus, deoxyribose, contains original code, deoxyribonucleic acid, contains Thymine, one typeRNA: single helix, leaves nucleus, ribose, is translated into protein, ribonucleic acid, contains uracil, several types
- It allows organisms to be able to exchange genetic information for the use of gene therapy/allows geneticists to study lab animals and apply it to humans.
- Adenine was always present in the same amount as Thymine, and Cytosine and Guanine were also present in the same amount (proportional to each other)
