• Illustrate the chromosome changes in interphase and mitosis using a diploid cell that is 2n=4 (two
large and two small chromosomes).
• Label the circles as G1 and G2 stages of interphase and each phase of mitosis (in order).
Draw the chromosome in each circle using the following guidelines.
1) For unreplicated chromosome draw a line (/) and for replicated chromosome draw an X.
2) For simplicity, do not indicate that the chromosomes are decondensed chromatin during
interphase.
●
3) Skip drawing the nuclear membrane or spindle fibers, since we are focusing on the
chromosomes.
• Label genes in the resulting daughter cells as A/a and B/b. (These letters represent genes which are
at icular places along the DNA molecule. Each chromosomes can have a thousand genes but we
are focusing on these two.
During recombination by the double strand break mechanism what is the structure of the intermediate with holiday functions pair to branch migration?Draw the structure taking three dominant alleles (ABC) on the parental duplex donoted by thin back lines and the parental duplex denoted by thick lines has recessive alleles (abc) show the difference between the DNA chain from the parental duplex and discuss the molecular mechanisms involved
• The image shows the sequence of tandem repetitive DNA (highlighted in green) at one
locus in the genome, with the copy of the locus on each chromosome within the
homologous pair shown (and listed as #1 and #2). Answer the following questions.
。 What type of repetitive DNA is shown? [Select]
• You want to do a PCR of this locus. If one primer's sequence is 5'-TCGAGGTTC-3',
then what is the second primer sequence needed to accurately PCR the locus?
Choose a primer of 9 bases long.
[Select]
。 You follow the PCR with an agarose gel electrophoresis. When preparing for agarose
gel electrophoresis, which electrode should be placed nearest the starting point of
the sample (the product of the PCR)? [Select]
。 Which allele would travel less far in your gel? [Select]
