Meiosis/Mitosis
The process by which a diploid (2n) cell forms gametes or haploid cells.
What is Meiosis.
The time interval between cellular reproductions.
What is Interphase
Name the process of duplicating DNA in preparation for cell division.
DNA Replication
Two-letter set that represents the alleles an organism possesses for a certain trait.
What is Genotype
What are the two reactants to photosynthesis?
Water and Carbon Dioxide
Haploid cells produced by diploid cells for the purpose of sexual reproduction.
What is Gametes.
The figure produced when the chromosomes of a species during metaphase are arranged according to their homologous pairs.
What is Karyotype.
Name the process of making a strand of RNA from a strand of DNA.
Transcription
An allele that will determine phenotype if just one is present in the genotype.
What is a Dominate allele.
True or false: Glycolysis is an anaerobic process; it does not require oxygen.
A three base sequence on DNA
What is a Triplet
The RNA that carries the information for protein synthesis.
What is mRNA
Which of the following is not part of a DNA molecule?
Nitrogen base
deoxyribose sugar
phosphate group
ribose sugar
Ribose Sugar
An allele that will not determine the phenotype unless the genotype is homozygous for that allele.
What is a Recessive allele
During cellular respiration where is energy from the breakdown of food stored?
ATP
(adenosine triphosphate)
Name the 4 phases of Mitosis in order.
prophase -> metaphase -> anaphase -> telophase
An organism that carries one or more genes from a different species.
What is a Transgenic organism.
A sequence of DNA has 120 nucleotides (it is not a complete sequence). How many amino acids would be the resulting polypeptide chain?
120 amino acids
240 amino acids
40 amino acids
12 amino acids
40 amino acids
since each codon contains 3 nucleotides and one codon codes for one amino acid, there would be: 120 divided by 3 equals: 40 amino acids in the polypeptide.
A cross between two individuals, concentrating on only one definable trait.
True or false:
NADPH is the electron carrier molecule for photosynthesis and NADH is the electron carrier molecule for cellular respiration.
Name the stages of Meiosis in order.
Prophase I -> Metaphase I -> Anaphase I -> Telophase I -> Prophase II -> Metaphase II -> Anaphase II -> Telophase II
The process, usually following mitosis or meiosis, in which the cytoplasm of a cell is divided in two.
What is Cytokinesis.
A cell's DNA consists of 12 pairs of homologous chromosomes. Answer BOTH: What is its diploid number? What is its haploid number?
The diploid number is 24
The haploid number is 12
The diploid number is 24 since twelve pairs make a total of 24 chromosomes (think 2 sets of 12 chromosomes) The haploid number is 12 because the haploid number is equal to the number of pairs.
Inheritance pattern in which heterozygotes have a phenotype intermediate between the phenotypes of the homozygotes.
What is Incomplete dominance.
When sunlight shines on a plant cell, what three things can happen?
Light energy is absorbed by pigments and used in the photosynthesis reactions.
Light energy can be transmitted.
Light energy can be reflected.
