Answer:

Explanation:

Restriction enzymes refer to enzymes that is produced by a bacteria which has the ability to cleaves DNA property to a specific restriction sequence site within the molecule.

Restriction enzyme is use to cut DNA into smaller fragments by preventing the replication of the phage DNA .

Restriction enzyme is use when there is infection or foreign materials that intrude into a bacterium,the bacterium uses it to defend itself against infections that might be cause by viruses, pathogens e.t.c.

Bacteria genome can be edited using CRISPR method. It is done with recombineering, which is a technique that uses phage recombination method to enhance homologous recombination of DNA fragments.

Which of the following is not a factor influencing preventive measures used to combat the spread of disease? A. Antibiotics B. S

Alchen [17]

C. Behavior

Although it does have some impact on the spread of disease, it is not a preventive measure to combat the spread of disease because it cannot be easily controlled.

EDIT: As my comment on the other answer states, this is incorrect. It is supposed to be a preventive measure, and antibiotics are not preventive, but behavior is.

Instructions: 1 Using the DNA sequence, make a complementary RNA strand from both the human and the cow. Write the RNA directly

Ksenya-84 [330]

Answer:

Please find the complete table attached as an image

Explanation:

This task is describing the processes of transcription and translation, which are the two processes involved in gene expression. The DNA of a human and cow is given in the table of the attached image and we're asked to transcribe into a complementary RNA, and subsequently translate into an amino acid using the CODON table (genetic code).

- Transcription is the process whereby DNA is used as a template for the synthesis of RNA based on complementary base pairing i.e. A-U, G-C, T-A etc.

- Translation is the process whereby RNA transcript is used to synthesize an amino acid sequence. The mRNA is read in a group of three nucleotides called CODON, where each of this codon specifies an amino acid.

The table has been completed and attached below. Note that in the amino acids row;

GLY means Glycine

ILE means Isoleucine

VAL means Valine

GLN means Glutamine

CYS means Cysteine

THR means Threonine

SER means Serine

PHE means Phenylalanine

ALA means Alanine

LEU means Leucine

What is the difference between threatened, endangered, and extinct species?

mario62 [17]

Threatened means they are lowering in numbers and nearing to be endangered.

Endangered means they are dangerously close to being extinct

Extinct means there is none of them left in the wild.

I hope this is what you meant.
