DNA replication

Biology
1 answer:
Luda [366]3 years ago
8 0

Answer:

d

Explanation:

The mechanism of DNA replication is semi-conservative. The two DNA strands are held together by hydrogen bonds between the nitrogen bases of the anti-parallel strands. During replication enzymes like helicase, topoisomerase and SSB protein break the hydrogen bonds for a short period. During that period, RNA primers from cytoplasm pair with each strand to give rise to two daughter DNA.

So a daughter DNA has one strand from the parent DNA and one new strand from the RNA primer.

What is the basis of the metric measurement system
solmaris [256]

The metric system is an alternative system of measurement used in most countries, as well as in the United States. The metric system is based on joining one of a series of prefixes, including kilo-, hecto-, deka-, deci-, centi-, and milli-, with a base unit of measurement, such as meter, liter, or gram. (got the answer from google hehe)

How does studying earths rocks and meteorites support the age of earth?
solniwko [45]

Answer:

Thousands of meteorites, which are fragments of asteroids that fall to Earth, have been recovered. These primitive objects provide the best ages for the time of formation of the Solar System. There are more than 70 meteorites, of different types, whose ages have been measured using radiometric dating techniques.

Meteorites that fall to Earth represent some of the original, diverse materials that formed planets billions of years ago. By studying meteorites we can learn about early conditions and processes in the solar system's history.

Umm.. maybe my answer is not what you needed

I'm sorry ❤️

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>
