The polio vaccine works as :

It triggers the immune system to produce antibodies to fight the disease causing agent.

Option 1 is the correct answer.

Explanation:

Polio vaccine is attenuated disease causing virus which helps in the production of antibodies to fight the disease. The immunity for polio gets develop in the individual given polio vaccines.

Jonas Salk discovered the the vaccine for polio by using inactivated polio causing virus.

The polio vaccine produces antibodies in the blood when interaction with polio virus is there.

The paralysis of the legs can be prevented as polio virus do not reach the nervous system and spinal cord of the individual.

There are two types of polio vaccines given across the globe:

oral polio vaccine and inactivated polio vaccine (via injection)

You experimentally change the DNA sequence directly upstream of a start codon of an operon in E coli to investigate the function
Phoenix [80]

Answer:

Mutation occurred in ribosome binding site that serves as binding site for 30S ribosomal subunit of <em>E. coli</em> and allows the process of protein synthesis to begin.

Explanation:

The initiation of protein synthesis in bacteria requires binding of the ribosome to the ribosome binding site. The ribosome binding site in bacteria consists of the initiation codon "AUG" and the preceding Shine-Dalgarno sequence. The AUG initiation codon and Shine Delgrano sequence are around 10 bases apart.

The sequence is polypurine hexamer and is represented by 5' ...AGGAGG...3'. Shine-Delgrano sequence is complementary to the conserved sequence present at the 3' end of 16SrRNA of the 30S subunit of the bacterial ribosome. Binding of Shine Delgrano sequence of ribosome binding site and the complementary sequence of the 30S ribosomal subunit marks the first step in the initiation of protein synthesis.

Any mutation in the ribosome binding site would not allow the process of protein synthesis to start or would reduce the rate of the initiation of protein synthesis.

Which is required for sexual reproduction? mitosis binary fission diploid cell production meiosis mitosis binary fission diploid
dsp73
Meiosis (SEXUAL cell division) is a type of Mitosis (cell division). 
Diploid cell production happens during meiosis when the haploid (n) cells from the parents divide into TWO diploid (2n) cells (which have the complete set of chromosomes from the parents). 

Basically, meiosis is required for sexual reproduction (unless in your question you can choose more than one answer...so it'll be meiosis, diploid cell production, mitosis)
