a scientist isolates all of the mrnas in a kidney cell and reverse transcribes them into dsdna. the dsdna copies are then insert
SVETLANKA909090 [29]

When the dsDNA copies are then inserted into vectors and cloned into E. coli. the scientist has produced a cDNA library.

A collection of DNA fragments that have been cloned into vectors to identify and isolate desired DNA fragments is known as the DNA library. cDNA libraries and genomic libraries are the two types of libraries.

cDNA (Complementary DNA )library: cDNA is a DNA copy of an mRNA molecule that is produced by reverse transcriptase, a DNA polymerase that can use RNA or DNA as its template.

  • These are made by using mRNA as their starting material as templates.
  • They only represent genes in the genome that are expressed under particular conditions.
  • Because cDNA lacks introns, prokaryotic cells can express it.

1. a) father (Rr), mother (rr)

b) from the attached file(1)

c) the possible genotypes are

  • Rr - 50%
  • rr - 50%

d) but from the information given above the only possible genotype for SpongeGerdy is Rr, because we were told that she was squarepants

e) Rr

f) from the attached file(2)

g) the possible genotypes are

  • RR - 25%
  • Rr - 50%
  • rr - 25%

h) the genotypes for squarepants are RR and Rr

therefore probability is (25 + 50)% = 75% or 3/4

i) the only genotype for roundpants is rr

therefore probability is 25% or 1/4

2. a) wilba - Ee , wilbur -EE

b) from the attached file(3)

c) the possible genotypes are

  • EE - 50%
  • Ee - 50%

d) the genotypes for round eye are EE and Ee

therefore probability is (50 + 50)% = 100% or 1

e) the only genotype for oval eye is ee

therefore probability is 0

3. a) squidward - BB . squidette - bb

b) from the attached file(4)

c) the only possible gene is Bb - 100% or 1

d) the genotypes for a light blue skin are BB and Bb

therefore probability is (0 + 100)% = 100% or 1

e) the only genotype for a light green skin is bb

therefore probability is 0

f) No, they are not. this is because they are heterozygous i.e.( they carry gene for a light green skin)

g) from the attached file(5)

h) the possible genotypes are

  • BB - 25%
  • Bb - 50%
  • bb - 25%

i) the genotypes for a light blue skin are BB and Bb

therefore probability is (25 + 50)% = 75% or 3/4

j) the only genotype for a light green skin is bb

therefore probability is 25% or 1/4
