Answer:
A scientific theory is an explanation of an aspect of the natural world that can be repeatedly tested and verified in accordance with the scientific method
Explanation:
<span>enzymes are resuable as they are biologically catalyst which speeds up the rate of a reaction without being chemically changed themselves. However, if the enzyme is to be denatured under unfavourable conditions (extreme temperatures, extreme pH), the enzymes may not be reusable once denatured.</span>
Answer:
b) mRNA codons are joined by tRNA anticodons to assemble amino acids to form a protein.
Explanation:
Answer:
- DNA to be cloned
- mature mammalian mRNA is isolated
- reverse transcriptase, provided with a primer, synthesizes a strand of cDNA without introns
- the mRNA is hydrolyzed by raising the pH
- a primer site is created on the ssDNA
- a complementary DNA strand is synthesized, forming a ds cDNA molecule.
- dsDNA
Explanation:
cDNA is the acronym for complementary DNA. This DNA is a single or double stranded moolecule that is synthesized from a messenger RNA molecule. This molecule is used in studies that aim to clone eukaryotic genes in prokaryotic individuals. The result of this is the expression of a protein from a eukaryotic individual in prokaryotic individuals.
To form a double-stranded cDNA molecule, the following steps would be required:
- DNA to be cloned
- mature mammalian mRNA is isolated
- reverse transcriptase, provided with a primer, synthesizes a strand of cDNA without introns
- the mRNA is hydrolyzed by raising the pH
- a primer site is created on the ssDNA
- a complementary DNA strand is synthesized, forming a ds cDNA molecule.
- dsDNA
