GENETIC PROCESSES
- MEIOSIS
- SEXUAL
REPRODUCTION
Anmerkungen:
- The production of new living organisms by combining genetic information from two individuals of different sexes.
- HAPLOID
Anmerkungen:
- (Of a cell or nucleus) having a single set of unpaired chromosomes.
- FERTILIZATION
Anmerkungen:
- The action or process of fertilizing an egg, female animal, or plant involving the fusion of male and female gametes to form a zygote.
- OOGENESIS
Anmerkungen:
- The production or development of an ovum.
- SPERMATOGENESIS
Anmerkungen:
- The production or development of mature spermatozoa.
- GAMETE
Anmerkungen:
- A mature haploid male or female germ cell that is able to unite with another of the opposite sex in sexual reproduction to form a zygote.
- ZYGOTE
Anmerkungen:
- A diploid cell resulting from the fusion of two haploid gametes; a fertilized ovum.
- ASEXUAL
REPRODUCTION
Anmerkungen:
- Mode of reproduction by which offspring arise from a single organism and inherit the genes from that parent only.
- SEX
CELLS
Anmerkungen:
- A cell responsible for transmitting DNA to the next generation.
- HOMOLOGOUS
CHROMOSMES
Anmerkungen:
- A set of one maternal chromosome and one paternal chromosome that pair up with each other inside a cell during meiosis.
- GENES
Anmerkungen:
- A unit of heredity that is transferred from a parent to offspring and is held to determine some characteristics of the offspring.
- CROSSING OVER
Anmerkungen:
- The exchange of genes between homologous chromosomes, resulting in a mixture of parental characteristics in offspring.
- KARYOTYPE
Anmerkungen:
- The number and visual appearance of the chromosomes of the nuclei of an organism or species.
- SEX
CHROMOSOMES
Anmerkungen:
- A chromosome involved with determining the sex of an organism, typically one of two kinds.
- KARYOTYPE
Anmerkungen:
- The number and visual appearance of the chromosomes in the cell nuclei of an organism or species.
- SYNAPSIS
Anmerkungen:
- The fusion of chromosome pairs at the start of meiosis.
- DNA
- PHOSPHATES
- DOUBLE
HELIX
Anmerkungen:
- A pair of parallel helices intertwined about a common axis, especially that in the structure of the DNA molecule.
- NUCLEOSIDES
Anmerkungen:
- A compound (cytosine, adenine, etc.) commonly found in DNA or RNA, consisting of a purine or pyrimidine base linked to a sugar.
- NITROGENOUS
BASES
Anmerkungen:
- A nitrogen containing molecule that has the same chemical properties as a base.
- THYMINE
- COMPLEMENTARY BASE PAIRS
- GUANINE
- COMPLMENTARY BASE PAIRS
Anmerkungen:
- Either of the nucleotide bases linked by a hydrogen bond on opposite strands of DNA or double-stranded RNA.
- ADENINE
- CYTOSINE
- DEOXYRIBOSE
Anmerkungen:
- A sugar derived from ribose.
- MITOSIS
- DIPLOID
Anmerkungen:
- (Of a cell or nucleus) containing two complete sets of chromosomes, one from each parent.
- SOMATIC
CELLS
Anmerkungen:
- Any cell of a living organism other than the reproductive cells.
- AUTOSOMES
Anmerkungen:
- Any chromosome that is not a sex chromosome.
- CELL
CYCLE
Anmerkungen:
- INTERPHASE
Anmerkungen:
- - Cells grow.
- Make structural proteins.
- Transport nutrients to where they are needed.
- Eliminate waste.
- Prepares for the next stages of mitosis.
- PROTEINS
Anmerkungen:
- CENTROMERE
Anmerkungen:
- The structure that holds chromatids together
- CHROMATIN
Anmerkungen:
- The tangled fibrous complex of DNA and protein within a eukaryotic nucleus.
- PROPHASE
Anmerkungen:
- 1st stage of cell division.
- CHROMOSOMES
Anmerkungen:
- Chromatin condenses into chromosomes.
- CENTROSOMES
Anmerkungen:
- Small protein bodies that are found in the cytoplasm of animals cells.
- SPINDLE FIBRES
Anmerkungen:
- Protein structures that guide chromosomes during cell division. Formed from centrosomes.
- METAPHASE
Anmerkungen:
- The chromosomes line up along the center axis of the cell.
- ANAPHASE
Anmerkungen:
- The chromosomes split up and chromatids are pulled to the opposite ends of the cell.
- CHROMATIDS
Anmerkungen:
- Each of the two threadlike strands into which a chromosome divides during cell division. Each contains a double helix of DNA.
- TELOPHASE
Anmerkungen:
- A nuclear membrane forms around each set of chromatids.
- CYTOKINESIS
Anmerkungen:
- Pinching off the cell into 2 parts.
- SISTER
CHROMATID
Anmerkungen:
- Pieces of identical DNA that are crucial in the process of cell replication and division.
