Based on the identification of T-cell receptor B variable gene segments in genomic DNA an estimation of the size of the human T-cell receptor B variable gene segment repertoire was embarked upon.

PCR amplification from uncloned and cloned genomic DNA sources, Southern blot hybridization, nucleotide sequencing, and cosmid cloning were used to identify  T-cell receptor B variable gene segments in numerous irrelevant individuals. The benefits of this strategy lead to many findings such as there was a possibility of discriminating between alleles at the products of different loci and the same locus, T-cell receptor B variable gene segments c expressed at very low levels in libraries of  Complementary DNA  are detectable. 63 unique T-cell receptor B variable gene segments were sequenced and identified .Out of 63 , 51 contained Thirty-four cosmid clones which were isolated and later filtered for the existence of further  T-cell receptor B variable subfamily members.The results were that human T-cell receptor B variable germline repertoire encodes at least 63 T-cell receptor B variable gene segments out of which 52 are functional.

Answer:

B. Photosynthesis will happen slower/less

Explanation:

Option B is the possible short-term effect on photosynthesis when the sun's rays are partially blocked.

Photosynthesis is the process whereby plants manufacture their own food with the use of sunlight and carbon dioxide. When this occurs, (energy in form of glucose) and oxygen are produced. The oxygen is released for animals to use.

Photosynthesis makes use of sunlight. But if sunlight is partially blocked, the process by which photosynthesis occurs becomes slow or less. This is because as the sunlight is partially blocked, there is no adequate supply of sunlight to carry out photosynthesis.

Explanation:

For example, enzymes are required for a proper digestive system function. Digestive enzymes are mostly produced in the pancreas, stomach, and small intestine. But even your salivary glands produce digestive enzymes to start breaking down food molecules while you're still chewing.

DNA replication results in two identical daughter molecules each consisting of one old (original) strand and one newly-synthesized strand. Therefore, it is true.

The process of duplicating the parent DNA helix into two identical daughter helices is known as DNA replication. One parent strand is passed down to each daughter strand in this semi-conservative procedure.

In prokaryotic cells, DNA replication takes place in the nucleoid area, whereas it happens in the nucleus in eukaryotic cells. Prior to cell division, DNA replication takes place in the S phase of the cell cycle.

Replication fork pairs that form at the origins of replication and then move in opposition to one another carryout genome duplication. When convergent replication forks meet, DNA replication is complete. Hence, it is true.

Explanation:

True. In mammals, an increase in the temperature of the preoptic area of the hypothalamus activates physiological mechanisms for heat dissipation including vasodilation.

Vasodilation, as it is known in medicine, occurs when blood vessels in your body open up, enabling more blood to flow through them and resulting in a reduction in blood pressure. Without your knowledge, your body goes through a routine procedure like this. It can also be brought on by the foods and beverages you consume as well as the drugs you take. Vasodilation may also be a sign of a particular illness.

The two of the many functions that your blood serves in the body:

Your body's blood arteries are more complex than simple tubes that remain constant in size. Your blood arteries include muscle as well, and that muscle regulates how wide or narrow they are at any particular time. Vasodilation occurs when blood vessels enlarge. Vasoconstriction is the opposite process, which occurs when blood vessels narrow and contract.

Explanation:

Mantle convection is the very slow creeping motion of Earth's solid silicate mantle caused by convection currents carrying heat from the interior to the planet's surface.

The Earth's surface lithosphere rides atop the asthenosphere and the two form the components of the upper mantle. The lithosphere is divided into a number of tectonic plates that are continuously being created or consumed at plate boundaries. Accretion occurs as mantle is added to the growing edges of a plate, associated with seafloor spreading. This hot added material cools down by conduction and convection of heat. .

Answer:

Sequencing DNA means determining the order of the four chemical building blocks - called "bases" - that make up the DNA molecule. The sequence tells scientists the kind of genetic information that is carried in a particular DNA segment.

Explanation:

Answer:

80%

Explanation:

Because both alleles (of homozygotes) exist in the progeny, codominance is also known as no dominance in some circumstances (heterozygote). As a result, the phenotype generated differs from the genotypes of the homozygotes.

The dominance in which the two alleles or characteristics of the genotype (of both homozygotes) are displayed jointly in children is referred to as codominance (phenotype). In cross-breeding, there is no dominant or recessive allele. Rather, the two alleles coexist and are generated as a combination of both alleles (that each allele has the tendency to add phenotypic expression during the breeding process).

Plants with white as the recessive allele and red as the dominant allele produce blooms with pink and white patches following cross-breeding, which is an example of codominance.

Answer:

True

Explanation:

The point where the separation of the DNA occurs is called the replication fork. Therefore, it is true.

The DNA double helix of a cell has been unwound and split into the replication fork, which is where DNA polymerases and other enzymes can work.

DNA helicases unwind DNA at locations known as origins during DNA replication, where synthesis will begin. The replication fork, so named because the two strands of DNA seem forked as they are unzipped apart, is a structure that is created while DNA helicase proceeds to unwind the DNA.

A replication bubble is created when the circular bacteria chromosome's double-stranded DNA is opened at the point of replication. A replication fork, a Y-shaped junction where double-stranded DNA is split into two single strands, is present at each end of the bubble. Therefore, it is true.
