Resource summary

Question Answer
RIBOSOMES ARE MADE OF PROTEIN & RNA
MOLECULE "UUA" IS A: tRNA
ANTICODON FOR METHIONE AUG
CAUSE(S) OF MUTATION DNA REPLICATION ERROR, EXTERNAL AGENTS, & MELOTIC ERROR
WHEN A BASE IS INSERTED/DELETED IN A MULTIPLE OTHER THAN 3, IT CAUSES A CHANGE IN THE AMINO ACID SEQUENCE FRAMESHIFT MUTATION
A MUTATION THAT OCCURS AT THE 3RD CODONE MAY HAVE NO EFFECT BECAUSE OF THE: WOBBLE EFFECT
A MUTATION THAT IS A CHANGE IN A SINGLE BASE IS: POINT MUTATION
IN EUKARYOTES, WHEN A PROTEIN IS MADE UP OF mRNA IS THE RESULT FROM WHEN THE GENE IS MADE UP OF: EXONS BECAUSE INTRONS HAVE BEEN REMOVED
ORGANISMS THAT HAVE GENETIC MATERIAL FROM ANOTHER ORGANISM SPLICED INTO ITS OWN TRANSGENIC ORGANISM
HERITABLE MUTATIONS OCCUR IN: GERMIME aka SPERMATOCYTES & DOCYTES
WHICH CHROMOSOMES PLAY THE LARGEST ROLE IN SEX DETERMINATION? Y
SEX LINKED GENES ARE LOCATED ON? X OR Y CHROMOSOMES
ON AN X-LINKED RECESSIVE DISORDER WHO IS MOST LIKELY TO EXHIBIT SYMPTOMS? MALES
X-INACTIVATION IS SEEN IN: FEMALES
GENES MAY BE AFFECTED BY THE ENVIROMENT TRUE
FOR ALL ORGANISMS "XY" MEANS IT IS MALE FALSE
HUMANS HAVE HOW MANY PAIRS OF CHROMOSOMES? 23
AUTOSOMES/SOMATIC CHROMOSOMES ARE RESPONSIBLE FOR: ALL TRAITS EXCEPT SEX
LINKED GENES BEHAVE LIKE ANY OTHER GENE COUPLE IN TERMS OF INHERITANCE. FALSE THEY DO NOT.
IN ORDER TO EXPRESS AN AUTOSOMAL RECESSIVE DISEASE THAT IS LETHAL, WHAT MUST HAPPEN? BOTH PARENTS MUST BE HETEROZYGOTIC
WHEN THERE IS A HETEROZYGOTE PHENOTYPE THAT IS DIFFERENT FROM A HOMOZYGOTE VERSION INCOMPLETE DOMINANCE
WHICH ALLELE REPRESENTATION IS A DOMINANT HOMOZYGOTE, HETEOZYGOTE. AABb
TRAITS THAT ARE CONTROLLED BY MULTIPLE GENES POLYGENIC
X-LINKED DISORDER TYPICALLY IS FOUND IN MALES
"CCGGCCGGCAAAUCCC" IS: mRNA
CGC IS tRNA
TRANSCRIPTION CHANGE FROM DNA TO mRNA
3 STEPS OF TRANSLATION INITIATION, ELONGATION, TERMINATION
ANTICODONS THE BASES FOUND IN tRNA
ALLELES DIFFERENT VERSIONS OF THE SAME GENES
THE MOST COMMON TRAIT IN A POPULATION IS THE DOMINANT FORM FALSE
THE ACTUAL CODING OF TRAITS IS CALLED GENOTYPE
THE PHYSICAL EXPRESSION OF GENES IS CALLED PHENOTYPE
THE LAW OF SEGREGATION ALLELES WILL MOVE APART DURING GAMETE FORMATION
THE LAW OF INDEPENDENT ASSORTMENT ALLELES OF DIFFERENT GENES MOVE INTO GAMETES W/O AFFECTING EACH OTHER IN POSITION
WHEN 2 DOMINANT ALLELES ARE BOTH EXPRESSED CO-DOMINANCE
THE NEGATIVE AFFECTS OF INBREEDING MAY MANIFEST BECAUSE INBREEDING ERROR TENDS TO BE A: RECESSIVE DISORDER
IN BACTERIUM THE REGION OF DNA THAT CAN REGULATE TRANSCRIPTION BY HAVING A REPRESSOR BIND TO THE OPERATOR
IN BACTERIUM THE REGION OF DNA WHERE THE RNA POLYMERASE BINDS IS THE PROMOTER
IN LAC OPERATION THE SIGNAL MOLECULE THAT BINDS WITH THE REPRESSOR IS LACTASE
MEOSIS OCCURS IN; YOUR TESTIES OR OVARIES
SOMATIC CELLS ARE NON SEXUAL CELLS
CELLS THAT ARE SPECIALIZED TO PRODUCE GAMETES GERM CELLS
HUMAN GAMETES HAVE HOW MANY CHROMOSOMES? 23
HUMAN ZYGOTE HAS HOW MAN CHROMOSOMES? 46
ALTERNATION OF GENERATION OCCURS IN? PLANTS
WHEN DOES CROSSING OVER OCCUR? PROPHASE 1
CROSSING OVER PROVIDES GENETIC DIVERSITY
THE OTHER SOURCES OF FENETIC DIVERSITY IN GAMETES IS PRODUCED BY? INDEPENDENT ASSORTMENT
FRATERNAL TWINS COME FROM TWO DIFFERENT ZYGOTES
MUTATION THAT OCCURS WHEN A CHROMOSOME LOOSES ONE OR MORE GENES IS KNOWN AS? DELETION
GERM CELLS THAT PRODUCE SPERM CELLS ARE KNOWN AS? SPERMATAGONIA
DURING MEIOSIS DNA REPLICATES DURING S PHASE
GAMETES FUSE TO FORM ZYGOTES
ORGANISMS HAVE SEX TO PRODUCE GENETICALLY DIVERSE OFFSPRING
DNA IS SYNTHESIZED DURING S PHASE
CHROMOSOMES LINES UP IN THE MIDDLE OF THE CELL METAPHASE
CHROMOSOMES PULL TO OPPOSITE POLES OF THE CELL ANAPHASE
NUCLEAR ENVELOPE DISSOLVES DURING S PHASE
NUCLEAR ENVELOPE REFORMS DURING TELOPHASE
THE DIVISION OF CYTOPLASM AND THE CELL IS CYTOKENESIS
ALL CELL TYPES CYCLE THROUGH THE CELL CYCLE MANY TIMES FALSE
THE CELL SPENDS MOST OF ITS LIFE IN INTERPHASE
CHROMOSOMES ARE MADE UP OF PROTEINS AND DNA
HUMAN DIPLOID CELLS HAVE HOW MANY CHROMOSOMES 46
HUMAN HAPLOID CELLS HAVE HOW MANY CHROMOSOMES? 23
SPERM CELLS ARE EXAMPLES OF HAPLOID CELLS
AN INDIVIDUAL WITH THE XY SEX CHROMOSOMES IS MALE
WHERE ARE HAPLOID CELLS PRODUCED OVARIES
THE TIPS OF EUKARYOTIC CHROMOSOMES THAT HELP CONTROL HOW MANY TIMES A CELL MAY DIVIDE TELOMETERS
UNCONTROLLED CELL GROWTH CANCED
APOPTOSIS PROGRAMMED CELL DEATH
ABNORMAL VARIANT OF GENES THAT NORMALLY CONTROL CELL DIVISION ONCOGENES
THE LOCATION/TIME PERIODS ON THE CELL CYCLE WHERE THE CELL REGULATES AND VERIFIES PROPER FUNCTIONS CHECKPOINTS
DEAD GUYS OF IMPORTANT WHO DISCOVERED THE STRUCTURE OF DNA WATSON AND CRICK
DNA MUST BE UNWOUND IN ORDER TO BE REPLICATED, THE ENZYME THAT DOES THIS IS HELICATE
DNA ENCODES FOR PROTEINS
DNA POLYMERASE MAY ONLY REPLICATE FROM 3 TO 5 END, THEREFOR EACH OF THE SIDES OF DNA MUST BE REPLICATED DISCONTINUOUSLY. THE CHUNKS THAT ARE REPLICATED AND THEN JOINED TOGETHER ARE CALLED OKAZAKI FRAGMENTS
ABILITY TO AMPLIFY DNA SAMPLES WAS INVENTED BECAUSE THERMOPHILIC BACTERIA FOUND IN HOT SPRING
DNA PROFILING WORKS BY USING RESTRICTION ENZYMES; THESE ENZYMES DO WHAT? CUT DNA AT A PARTICULAR NUCLEOTIDE SEQUENCE
IN ORDER TO SEQUENCE DNA WE NEED TO USE WHAT? TERMINATOR NUCLEOTIDE TO CREATE DIFFERENT LENGHTS OF DNA
DNA REPLICATION OCCURS IN THE NUCLEUS
MOST OF OUR DNA HAS NO KNOWN FUNCTION TRUE
GENETIC MATERIAL IS DNA
ERROR DURING DNA REPLICATION MUTATION
ELECTROPHORESIS GEL DNA TRAVELS THROUGH THE GEL AND IS SEQUENCED. THE LARGER FRAGMENTS MOVE SLOWER AND THEREFOR ARE ON THE BOTTOM OF THE GELL
MICROARRAY METHOD ANOTHER WAY TO SEQUENCE DNA; MUCH FASTER THAN GEL
WHICH ENZYME HAS PROOF READING FUNCTION IN ORDER TO REDUCE REPLICATION ERRORS DNA POLYMERASE
NUCLEOTIDES OD DNA ARE COMPLIMENTARY WHICH MEANS FOR EVERY PURINE BASE THERE IS AN EQUAL AMOUNT OF PYRIMADINE BASES (A & G TO T &C)
