Meiosis & Genetics
A process during meiosis where homologous chromosomes exchange/swap genetic material, increasing genetic variation.
What is "crossing over"?
This nucleic acid has a sugar-phosphate backbone, contains the sugar "ribose" and has bases of adenine, uracil, cytosine and guanine.
What is "RNA"?
This enzyme builds new DNA strands by adding complementary nucleotides during DNA replication.
What is "DNA Polymerase"?
Transcription, the process of converting DNA into mRNA codons, occurs in this specific location of a cell during protein synthesis.
What is "the nucleus"?
This is the number or CONCENTRATION of organisms/individuals of a population in a given area.
What is "population density"?
This term describes cells that contain one set of chromosomes (n), such as sperm or egg cells.
What is "haploid"?
These are the monomers of nucleic acids such as DNA or RNA.
What are "nucleotides"?
This enzyme is responsible for "unzipping" a DNA strand, separating the double helix and preparing it for DNA Replication.
What is "helicase"?
This type of RNA carries genetic instructions from DNA to the ribosome during protein synthesis.
What is "mRNA"?
This population dispersion type describes when organisms arrange themselves in groups.
What is "clumped" dispersion?
This term describes having two of the SAME alleles of a gene - one inherited from each parent.
What is "homozygous"?
What are a "sugar, phosphate and nitrogenous base"?
This enzyme produces a short RNA primer to begin DNA synthesis.
What is "primase"?
These are the monomers of all proteins and link together to form polypeptide chains.
What are "amino acids"?
This ecological relationship often occurs between two or more organisms when there is limited food, space or resources.
What is "competition"?
Suppose an insect contains 30 chromosomes in its somatic cells. How many chromosomes would you expect to find in each of its gametes?
What is "15 chromosomes"?
This molecules contains a sugar-phosphate backbone with the sugar deoxyribose, uses the bases adenine, thymine, cytosine and guanine.
What is "DNA"?
This enzyme seals fragments of DNA together by forming bonds in the suga-phosphate backbone at the end of DNA replication.
What is "ligase"?
This is the name for the idea that DNA --> RNA --> Proteins.
What is the "Central Dogma"?
What are "abiotic factors"?
These are "observable characteristics or traits" of an organism, resulting from the interaction of its genotype or environment.
What is a "phenotype"?
This is the term to describe the overall shape of DNA.
What is a "double helix"?
DNA replication pairs up nitrogenous bases in a certain way. Replicate this sequence: ACG CCA
What is "TGC GGT"?
This enzyme is responsible for producing an mRNA strand during transcription, by adding nucleotides one at a time.
What is "RNA Polymerase"?
This term describes the maximum population that can be achieved based on available resources and space.
What is "carrying capacity"?
