What is the function of histones- proteins that aide in dna replication

Biology
1 answer:
makkiz [27]3 years ago
6 0

Answer:

Nucleosomes in turn are wrapped into 30-nanometer fibers that form tightly packed chromatin. Histones prevent DNA from becoming tangled and protect it from DNA damage. In addition, histones play important roles in gene regulation and DNA replication. Without histones, unwound DNA in chromosomes would be very long.

What type of vertebrae have openings in their transverse processes that guide the vertebral arteries up toward the brain?
Kaylis [27]

Answer:

Cervical vertebrae

Explanation:

The cervical vertebrae are the vertebrae present in the neck region. All cervical vertebrae are characterized by the presence of three foramina. One is the vertebral foramen and the rest two are called transverse foramina. Each transverse process of each cervical vertebrae contains a transverse foramen. The vertebral artery and the related vein and nerve fibers pass through the transverse foramina. Among the all cervical vertebrae, the transverse processes and transverse foramina of the atlas are relatively larger.

VMariaS [17]
The RODS detects shades of grey and are responsible for peripheral vision, while the CONES are responsible for colour vision and seeing fine details. 
Rod cells are photoreceptor cells that are located on the retina of the eyes. Rods cells are usually concentrated at the outer edge of the retina and they are use in peripheral vision. Cones on the other hand are photoreceptor cells which are responsible for colour vision and they work best in bright light.

Un instructor desea preparar un experimento sobre movimiento armónico simple. Sólo dispone de una masa de 2 kg pero tiene una co
Sergeeva-Olga [200]

Answer:

Constante de resorte, k = 19.745 N/m

Explanation:

<u>Dados los siguientes datos;</u>

Masa, m = 2 kg

Periodo, T = 2 segundos

Para encontrar la constante del resorte, k;

Period, \; T = 2 \pi \sqrt {\frac {m}{k}}

Dónde;

  • T es el período.
  • m es la masa del objeto.
  • k es la constante del resorte.

Haciendo k el tema de la fórmula, tenemos;

k = \frac {(2 \pi )^{2}m}{T^{2}}

Sustituyendo en la fórmula, tenemos;

k = \frac {(2 * 3.142)^{2} * 2}{2^{2}}

k = \frac {6.284^{2} * 2}{4}

k = \frac {39.49 * 2}{4}

k = \frac {78.98}{4}

<em>Constante de resorte, k = 19.745 N/m</em>
