Answer:
All given options are correct.
Explanation:
Biomolecules may be defined as the organic molecules that are present in the living organism. Four important biomolecules are proteins, carbohydrates, fats and nucleic acids.
The biomolecules are known as macromolecules because they are made of large units of molecule. The mRNA that translates to form a enzymes is macromolecule because RNA is made of large units of nucleotides. Lipid that found in cell membrane are macromolecules because they are made of more than 1000 atoms. Protein that are involved in DNA replication are macromolecules as they have large units of amino acids.
Thus, all the given option are correct.
1) Birthrate. Because you need to accommodate for all the little humans on earth, whether that be housing or taxes and such. Plus we don’t want overcrowding in certain areas.
2) death rate. It’s important to look at the death rate of a population because it can show the condition quality of certain areas. If a place has a higher death rate or the rate increases too quickly, then that should signal that something is wrong.
Answer:
b. A second marker in the knock-out cassette, that if inserted into the genome results in cell death when plated on selective media.
Explanation:
General recombination, also known as homologous recombination, refers to the naturally occurring process of exchange of genetic material between pairs of homologous DNA sequences. This process (homologous recombination) can be exploited by genetic engineering to insert DNA segments of interest at target genes. Moreover, a cassette is a mobile DNA segment containing almost a gene and a recombination site, which is integrated into the <em>locus</em>/<em>loci</em> of interest by homologous recombination. A cassette may contain a DNA segment called 'negative marker' which prevents growth under particular conditions, while a positive marker permits growth under certain conditions. In consequence, a second marker consisting of a drug cassette may be used as a negative marker in order to evidence its insertion by inducing cell death when they are plated in selective conditions.
