You have cloned a gene for an enzyme that degrades lipids in a bacterium that normally lives in cold temps. you wish to use this
GaryK [48]
A) You would have to incorporate that gene into the bacteria's plasmid (genetic information that isn't in its main genome) so that it can use it and express its message. This is done using enzymes that cut that circular plasmid, insert the gene you want, and put the circular molecule back together. Once you have the bacteria with the plasmid in it, you replicate that bacteria, so all the resulting copies will have that gene and they'll express it.

B) If not enough protein is being produced it could be because you don't have enough bacteria, you'd need a bigger population. The medium the bacteria is in also should be optimal so that it can be as efficient as possible.

The following question deals with the ABO blood group. Recall that A and B alleles are co-dominant over the allele O. Jill, who
kiruha [24]

Answer: Jack has the genotype Bo; Jill is AB; Jack's mother is OO.

Explanation: In the ABO blood type, the alleles A and B are dominant over O. However, the allele A is co-dominant with the allele B. That means an individual can have a genotype AB, which is Jill's case: her blood type has the two allele. For Jack's mother, her blood type is O. As O is recessive, her genotype will be OO, indicating the recessiveness. For Jack, his mother is recessive, so he will have genotype heterozygous for blood type B, which means BO.

Which group is noted for the independence of gametophyte and sporophyte generations from each other?
Ratling [72]
<h2>Gametophyte and Sporophyte Generations</h2>

Explanation:

  • <em>The sexual stage, called the gametophyte generation,</em> produces gametes, or <em>sex cells, and the abiogenetic stage, or sporophyte age, </em>produces spores abiogenetically
  • As far as chromosomes, the <em>gametophyte is haploid</em> (has a solitary arrangement of chromosomes), and the <em>sporophyte is diploid (has a double set)</em>
  • All aquatic plants have alternation of generations. In mosses and their <em>family members (Bryophytes), the haploid gametophyte is the predominant age,</em> and the diploid sporophytes are sporangium-bearing stalks developing from the gametophytes
