if a scientist wanted to compare the expression of one gene under two sets of conditions, what technique would they use?
timurjin [86]

If a scientist wanted to compare the expression of one gene under two sets of conditions, chain termination is the technique they would use.

Chain termination is any chemical response that ceases the formation of reactive intermediates in a sequence propagation step withinside the route of a polymerization, efficaciously bringing it to a halt.

Sanger sequencing, additionally referred to as the “chain termination technique”, is a way for figuring out the nucleotide collection of DNA. The approach become evolved with the aid of using time Nobel Laureate Frederick Sanger and his colleagues in 1977, subsequently the call the Sanger Sequence.

Mendel’s law of independent assortment states that alleles of genes on nonhomologous chromosomes assort independently during gam
Lera25 [3.4K]

The mix of alleles from various genes that end up in the daughter cells is determined by the anaphase 1 of meiosis 1.

Chromosome segregation during meiosis is mirrored in the segregation of alleles. During anaphase, 1 of meiosis 1 homologous chromosomal separation leads to allele segregation.

Chromosomes display autonomous assortment when they are randomly split into daughter cells during meiosis.

<h3>What takes place in anaphase 1?</h3>

During meiosis I, sister chromatids remain together as homologous chromosomes separate. To appreciate the development of germ cells, it is crucial to comprehend how this odd chromosomal segregation behavior came to be. Here, we show that the pattern of chromosomal segregation during meiosis I is determined by the microtubule-kinetochore interactions that are inhibited during prophase I and the premeiotic S phase.

List, in order, all the vessels blood must flow through to get from the abdominal aorta into the kidney and back to the inferior
Alenkasestr [34]

Answer:

Kidneys are the important organ of excretion. Human kidneys are bean shaped located below the rib cage. Different vessels are involved in the transportation of blood from the abdominal aorta  and back to the inferior vena cava.

The order of blood vessels are:

The blood enters in the aorta and and moves to the renal artery. Then the blood moves to the interlobar artery via segmental artery. The blood enters in the afferent glomerular arteriole from the arcuate artery and cortical radiate artery. Glomerulus receive the blood from the afferent glomerular arteriole. Then, the blood moves to the efferent glomerular arteriole. The blood then enters in the cortical radiate vein via peritubular capillaries and vasa recta. The blood moves back to the inferior vena cava from the arcuate vein, interlobar vein and renal vein.
