A recombinant plasmid created during a recombinant DNA experiment:

Biology
1 answer:
Rama09 [41]3 years ago
4 0

Answer:

B.carries and allows expression of a foreign gene of interest.

Explanation:

Plasmids are the low molecular weight extrachromosomal DNA molecules that are able to replicate themselves independent of chromosomal DNA due to the presence of "ori" (origin of replication).

Plasmids serve as vectors in recombinant DNA technology as some of their genes can be replaced with the gene of interest to create recombinant plasmids.

The restriction enzymes that create the sticky ends and DNA ligases facilitate the insertion of the foreign gene into the plasmids.

The host cells are made competent to take up the recombinant plasmids. Once inside the host cell, the recombinant plasmids replicate themselves and express the gene of interest that they carry.

Why do organisms found at low temperature have membrane proteins with a higher percentage of alpha helices compare to beta sheet
Art [367]

Answer:

Protein is the important biomolecule that acts as building block of the protein. Proteins are inserted into the biological membrane and consists of transmembrane and integral membrane proteins.

The alpha helices and beta sheets are present in the bio membrane. The organism living at low temperature has high alpha helices and low beta sheets because alpha helices has high mobility, less rigidity and makes enzyme active at low temperature.

Three species of lizard, labeled A, B, and C, are being studied using molecular analysis by two research colleagues in different
Andreyy89

Answer:

The most appropriate answer would be option B.

The flaw in their reasoning is that they compared different molecules in a different set of organisms.  

For example, they compared the DNA of lizard A and B whereas they compared the RNA of lizard B and C.

In addition, the mutation rates of different molecules (DNA and RNA) are different and thus, comparison of DNA in one set of organism and comparison of RNA in another set cannot be used as the basis for the conclusion.

You observe that your friend has dimples. dimples result from the presence of the dominant gene d; absence of dimples is a homoz
anzhelika [568]

Answer:

DD or Dd

Explanation:

Dimples is the dominant trait (D). Your friend has dimples so that means he or she should have at least one allele of the dominant trait to express that trait. So your friend would either be homozygous dominant (DD) or heterozygous dominant (Dd). Notice that there is a recessive allele in the second. Even with that present, dimples would be still expressed.
