What is in easy way to remember what the diploid number is for any haploid number?
Multiply the haploid number by two.
100
What is an easy acronym to remember the stages of mitosis?
IPMAT
100
What is the purpose of meiosis?
Diploid cells producing haploid cells for use in sexual reproduction
100
What is the purpose of translation?
to make proteins
100
What is the purpose of transcription?
To create a version of the DNA message that can be carried out of the nucleus to the ribosomes.
200
What does the haploid number represent?
The number of homologous chromosome pairs inside an organism's genome.
200
When plants grow roots through the soil, what is going on?
The root lengthens as new root cells continually add to the root by mitosis.
200
Meiosis comes in two stages. How can we tell the difference?
Meiosis 1 produces two haploid cells with duplicated chromosomes. Meiosis 2 produces four haploid cells with non duplicated chromosomes.
200
What is going on during translation?
Ribosomes read the mRNA sent from the DNA to call for tRNA which bring amino acids to make proteins
200
Where does transcription take place?
inside the cell nucleus.
300
Why are homologous chromosome pairs a pair?
One half of the pair is DNA from the mother and the other half is DNA from the father
300
What is the difference between telophase and interphase?
Telophase is at the end of mitosis with new nuclear membrane being formed for the two new daughter cells. interphase is the cell at normal homeostasis
300
How is meiosis in female animals different than meiosis in male animals?
Female meiosis only produces one working gamete for every four haploid cells produced.
300
Where does translation occur?
In the cytoplasm of the cell.
300
What are the differences between mRNA and DNA?
ribose vs deoxyribose. single strand vs double strand, uracil vs thymine
400
Does the number of homologous chromosome pairs relate to the intelligence of the organism?
No
400
Why does mitosis duplicate the chromosomes during prophase?
so that each new daughter cell has a complete copy of the DNA.
400
In what ways is meiosis different than mitosis?
Mitosis and meiosis produce different products, and for different purposes. Diploid vs haploid, asexual reproduction vs sexual reproduction.

translate this tRNA into mRNA: A U G C A C
U A C G U G
400
What is the DNA corresponding to this mRNA strand? U A C C G A
A T G G C T

A human being has a diploid number of 49. Is something wrong and why?
Yes, something is wrong. The person has 3 additional chromosomes because humans diploid number is 46.
500
What is the difference between metaphase and late interphase?
Metaphase has all chromosomes lined up at the equitorial plane. Late prophase is starting to move the chromsomes there.
500
How come all the haploid cells produced by meiosis are not all genetically the same?
For genetic variation in the species to ensure a better chance of survival. Also, it is beautiful.
500
Translate this DNA into its matching tRNA T C G A C T
mRNA = A G C U G A tRNA = U C G A C U

Describe how viruses "hijack" transcription.
viruses have their DNa read to create virus mRNA which then instructs the cell to make more viruses which is bad.
