The levels of environment are arranged by population, species, community, and last the ecosystem. ~Glad to help.
Answer:
D) Yes, it is important that the single-stranded DNA have 3′ ends, so resection must occur in the 5′ to 3′ direction.
Explanation:
During homologous recombination, the exonucleases remove nucleotides from the free 5' ends of the DNA at the double-stranded breaks to create a double-strand gap.
Removal of more nucleotides from the free 5' ends creates 3' single-strand extension which in turn invades the intact homolog and pairs with its complementary sequence of the DNA. The invaded free 3' end is then extended by DNA polymerase to give rise to Holiday junctions.
If the resection occurs in the opposite direction and creates overhangs with free 5' ends, the free 3' ends would not be available to serve as a primer to facilitate the replication.
Insulin is used . It involves a long process with bacteria and genes to extract the insulin safe for humans .
The answer is D, polypeptide synthesis.
Translation means translating the code in RNA to actual protein chains. In other words, this is the process of synthesizing peptide chains (aka polypeptides).
Think of it as "translating" the genetic message into actual materials used in the body.
