Answer:

DNA replication

Explanation:

DNA replication is the process whereby the genetic material (DNA) duplicates itself into two identical copies. This process must occur prior to any cellular division (meiosis or mitosis) in order to ascertain that each daughter cell gets an even and correct amount of DNA.

The process of DNA replication begins with the unwinding of the double stranded DNA molecule into two single strands of DNA. One strand called leading strand runs from 3'-5' while the other strand runs from 5'-3'. However, DNA replication proceeds in the 5'-3' direction.

Luda [366]

This is the law of similarity. This is a heuristic that the brain uses to group things together that seem to be the same, but might have subtle differences. We tend to not be able to see those differences as easily, and our brains tend to group the objects together that have higher-level similarities (color, shape, size) and see them as a single object.

Compare each patient's cdna sequence to the wild-type cdna sequence. Each patient has one nucleotide-pair substitution mutation.

Lera25 [3.4K]

The mutation is a change in the nucleotidic sequence. In the exposed example, Patient 1: nucleotide 143, TTC⇒TGC. Patient 2: nucleotide 143, TTC⇒TCC. Patient 3: nucleotide 147, TTC ⇒ TTG.

<h3>What is a mutation?</h3>

A mutation is a change or alteration in DNI sequences that introduce new variants.

Many of these are eliminated, but some of them might succeed and be incorporated into each individual.

These mutations are the ones that have been selected by natural selection.

<h3>Solving the problem</h3>

We know that each sequence initiates with nucleotide number 103 and ends in nucleotide 162.

So first, we will number the nucleotides, from 103 to 162. Each nucleotide has a number in increasing order.

Now, we will identify the mutations in each of the strands by comparing them with the wild-type sequence. The mutation occurs in one of the nucleotides, so we must look for the change in the bases.

Finally, we will identify the nucleotide location of each mutation.

nucleotide wild-type mutated

location nucleotide nucleotide

Patient 1 143 TTC TGC

Patient 2 143 TTC TCC

Patient 3 147 TTC TTG

Relaciona cada acontecimiento del ciclo cardíaco con alguno de estos términos diástole, sístole auricular o sistole ventricular

elena55 [62]

Answer:

El ciclo cardíaco consta de dos períodos i. mi. diástole y sístole.

Explicación:

El ciclo cardíaco consta de dos períodos i. mi. La diástole es aquella durante la cual el músculo cardíaco se relaja y se llena de sangre, mientras que la sístole es un período de contracción y bombeo de sangre. La diástole ventricular es el momento en el que las dos cámaras inferiores del corazón conocidas como ventrículos se relajan para permitir que la sangre fluya hacia adentro. La diástole auricular es el momento en que las dos cámaras superiores del corazón llamadas aurículas se relajan y permiten que la sangre fluya en.
