ddNTPs have a hydrogen at 3' position which terminates synthesis of DNA.

ddNTPs is the abbreviated form for dideoxynucleotides triphosphates. They are known as chain elongating inhibitors. The Sanger method is a sequencing technique that is used to increase the number of DNA copies. The DNA synthesis requires magnesium ions, a single-stranded DNA template, oligonucleotide primer, and nucleotide precursors like dATP, dGTP, dTTP, and dCTP. Also, DNA polymerase is required which is an essential component for DNA synthesis.

The Sanger sequencing method is a significant process evident by its use in Human Genome Project which helped scientists in sequencing the human genome. The small sequenced fragments are joined together to form large regions subsequently forming chromosomes.

What is the principle for dating materials using radioactive isotopes
nevsk [136]

It is based on a comparison between the observed abundance of a naturally occurring radioactive isotope and its decay products, using known decay rates.

<h3>How are isotopes used in radioactive dating?</h3>

These isotopes decay within the rocks according to their half-life rates, and by choosing the fit minerals and measuring the relative amounts of parent and daughter isotopes in them, the date at which the rock crystallized can be determined.

Thus, It is based on a comparison between the observed abundance of a naturally occurring radioactive isotope.

Question 1 (5 points)
lora16 [44]

Answer:

Electricity, gravity of earth and structure of atom provide evidence.

Explanation:

The investigation of electricity, gravity of earth and structure of atom helps the student to understand that without touching, one object apply force on another object. In electric current, we can see the property of magnetism due to which it attract and repel objects while in gravity of earth, the earth apply gravitational force to attract objects towards itself. in the structure of atom, proton present in the nucleus which attract the electron present in the shells.

Which correctly lists the three parts of soil that are classified by their particle size? bedrock, humus, and clay clay, bedrock
Alecsey [184]

Answer:

The correct option is;

Sand, clay, and silt

Explanation:

The categorization of soil particles by size can be made into three classes including sand (particle size between 0.05 mm to 2 mm), silt, (particle sizes between 0.002 mm to 0.05 mm) and clay (particle sizes lesser than 0.002 mm), larger particles such as stones, pebbles, boulders and rock other fragments are left out of the textural classification because of their inertness

The combination of the three particle sizes can be found in most soils and their relative proportion defines the texture of a given sample of soil.
