Answer:

A. alleles.

Explanation:

A gene is a physical segment of DNA which contains the code for a particular protein determines the trait of an organism.

The genes are present on the homologous chromosomes in the form of two variants or the alternative forms called "Alleles". The position where these alleles are present on the chromosome is known as a locus.

The alleles show their effect only when the two form of alleles (one from each parent) come opposite to each other during fertilization.

Out of these two alleles, the allele which shows its effect is called the dominant allele and the allele which is suppressed in the generation is known as a recessive allele.

Thus, Option-A is the correct answer.

To identify the molecule that accepts CO2, Calvin and Benson manipulated the carbon-fixation cycle by either cutting off CO2 or
sweet-ann [11.9K]

Answer:

The CO2 acceptor concentration would increase when the CO2 is cut off, but decrease when the light is cut off.

Explanation:

Calvin's light-independent reactions cycle breaks down on three basic stages: fixation, reduction, and regeneration.

All organisms need energy to perform life functions, and energy that is released is reused in other ways. Some plants have evolved mechanisms to increase the CO2 concentration in their leaves under hot and dry conditions.

When cloning a gene, one of the steps is to use restriction enzymes to insert the gene of interest into a vector. If you separat
nikitadnepr [17]

The question is incomplete as it does not have the options which are:

The empty vector would migrate the same distance as the cloned vector.

It is impossible to know without knowing the identity of the gene of interest.

The empty vector would migrate farther down than the cloned vector.

The cloned vector would migrate farther down than the cloned vector.

Answer:

The empty vector would migrate farther down than the cloned vector.

Explanation:

In recombinant technology, an empty vector is considered a vector which is present without the gene of interest and thus is of small size and the cloned vector is the vector which has a gene of interest along with the usual sequence.

The cloned vector is larger compared to the empty vector as the cloned vector has a gene of interest whereas the empty vector does not have.

In-gel electrophoresis technique, the DNA samples are run and the size of the fragment is known according to the ladder sequence which is used as a reference and have the band size in increasing order from lower side to upper side.

When the vectors sun on the gel, the small size gene will move faster and to the farthest distance compared to the larger DNA that is empty vector will cover the maximum distance while the cloned vector will cover the less distance.

Thus, the selected option is correct.
