Transcription
The complimentary RNA strand for this sequence of DNA: ATC GTA CCT
What is: UAG CAU GGA
T/F: mRNA molecules recognize each base codon and bring a matching amino acid to the ribosome
False, tRNA molecules do this
A nonsense mutation does this:
what is: codes for a stop codon
This is when and where meiosis occurs in animals:
What is: Only in the gonads (testes/ovaries), to make haploid gametes (sperm and egg) for sexual reproduction
When and where does mitosis happen?
What is: asexual reproduction, somatic cells, all the time
Which direction does RNA polymerase move in
What is: 5' to 3' Nucleotides can only be added onto the 3' end
The ribosomal subunits attach to mRNA and attract tRNA carrying ribosomes in this step
What is, Initiation of translation
A silent mutation does this:
What is: changes nothing; new nucleotide sequence codes for the same amino acid as the original
The reason meiosis is important:
What is: it increases the genetic variation of offspring
Prophase
chromatin condenses into chromosomes, hot pink nucleolus disappears, nuclear membrane breaks up
In Eukaryotes, this happens during mRNA processing:
What is: introns are cut out and exons are spliced together
This happens in Elongation of Translation
What is, tRNA attaches the next anticodon, bringing a new amino acid which binds to the first
A missense mutation does this:
what is: changes the amino acid; new nucleotide sequence codes for a different amino acid than original
The difference between anaphase 1 and anaphase 2
What is; In anaphase 1, the members of a chromosome pair are separated. In anaphase 2, sister chromatids are separated
Metaphase
What is: sister chromatids move to the middle of the cell and spindle fibers attach to the centromeres
Transcription occurs here:
What is, in the nucleus
This happens in termination of translation
One or more nucleotides are inserted or deleted, resulting in mRNA that codes for the wrong SEQUENCE of amino acids
What is: frameshift mutation
This happens in prophase 1:
what is: synapsis & crossover
Anaphase
Sister chromatids are pulled apart
The end result of transcription:
What is, DNA-> mRNA
The end result of translation:
What is, mRNA-> protein
What is this an example of:
ATG CGC -> TAC GAC G
What is: Insertion
The end result of meiosis:
What is: 4 Haploid Cells
The difference in cytokinesis between plants and animals
What is: in plants, a cell plate forms; in animals, a cleavage furrow forms
