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)
