Plasmids are used in genetic engineering to reproduce RECOMBINANT genetic material. When a plasmid is inserted a bacterium, the bacterum is encouraged to multiply, creating more copies of the recombinant DNA.

It is a circular piece of DNA that acts as a vector (a carrier of the gene). it attaches to the gene that is to be genetically engineered to form recombinant DNA (combined DNA of two different organisms). It allows the gene to be carried to a host cell to be replicated producing many identical genes. To cut open the plasmid requires an enzyme called restriction endonuclease and to stick the gene into the plasmid requires an enzyme called ligase

The chaparral biome has little biodiversity and is home to only a few well-adapted species.

This is false

Even though it might seem true, it's false because people often mix it with desert biome due to it's rigid and dry climate. However, the caparral biome has more rainfall, which is why there are many different plant species and trees, as well as animals.

ASAP You are observing proteins in a lab for an experiment. During transport, they have started to unwind and lose their shape.
GREYUIT [131]

Answer:

C. Secondary

Explanation:

In proteins, the structure of local segments can be arranged into three different three-dimensional formations: alpha helices (α-helix), beta sheets (β-strand) and omega loops. An alpha helix is the most common secondary protein conformation because it has low-energy and a stable arrangement. The α-helix is formed by the interaction between amino acids of every backbone N−H hydrogen bonded with the backbone C=O group of the corresponding amino acid residue in the polypeptide chain. The α-helix motif is very common in transmembrane segments of proteins that cross the lipid bilayer.

timama [110]

Answer:

Amylase-  alpha amylase in salivary glands and pancreatic amylase in pancreas

peptidase - stomach (chief cells)

lipase - pancreas

HCl - (parietal cells)

bile - liver

Explanation:

Alpha-amylase which is an enzyme also known as ptyalin is produced in the salivary gland and found in the saliva helping in the first step in the hydrolysis of starch. The leftover starch molecules are further broken down by the pancreatic amylase produced in the pancreas. Peptidase is secreted in the chief cells of the stomach and they catalyze the breakdown of proteins into smaller polypeptides or single amino acids. Lipase is produced from the pancreas and converts fats to fatty acids. HCl also produced in the stomach aids in the process of digestion in the stomach. Bile produced by the liver is involved in the emulsification of fats.
