The technology that could be used to identify Alexei DNA technology or Y-chromosome analysis.

<h3>How is the DNA test done to determine paternity?</h3>

The paternity test is carried out through DNA, and aims to verify the degree of kinship between the person and his supposed father. This test can be done during pregnancy or after the baby is born by analyzing the blood, saliva or hairs of the mother, child and the alleged father.

<h3>What is Y chromosome analysis?</h3>

The Y Chromosome test is mostly used to determine if there is a paternal relationship between two males. It is an extremely accurate and conclusive test and can be used in different situations. Any two males who are connected by a direct line can have this test done in order to determine relationship.

With this information, we can conclude that Genetic testing is a type of medical test that identifies changes in genes, chromosomes, or proteins.

In DNA replication, continuously synthesis occurs on the leading strand Multiple choice question. toward the origin of replicati
Tamiku [17]

Answer:

toward the origin of replication

Explanation:

A replication fork is a structure formed during DNA replication when specific enzymes (i.e., helicases) separate both DNA strands at the origin of replication. DNA is always synthesized in the 5' to 3' direction, thereby DNA can be synthesized continuously on the leading strand, because the growth of this strand proceeds in the same direction as the movement of the replication fork, while DNA synthesized in several short segments on the lagging strand which are called 'Okazaki fragments'. DNA polymerases are enzymes that can only add nucleotides to the 3' end of a DNA strand, thereby they require the synthesis of short stretches of RNA or 'RNA primers', which are necessary for DNA replication of the lagging strand.

Is it true that the breakdown of food molecules in the gut does not require coupling of atp hydrolysis, but enzymes are required
77julia77 [94]
The statement is true.  Digestion of food molecules in the digestive system in the gastrointestinal tract does not require coupling of ATP hydrolysis; but instead requires enzymes that speed up the spontaneous reaction. Enzyme digest specific food substrates at different parts of the digestive system until the final useful products of these enzymatic reactions are absorbed to the body metabolism.
