After a molecule of DNA replicates, two double-stranded molecules are formed. This results in a total of four strands of DNA.
Answer:
El material genético es importante porque le dice a sus células cómo funcionar y ayudarlo a sobrevivir.
Explanation:
The question is incomplete as it does not have the options which are:
A) eight legs.
B) two pairs of antennae.
C) a sessile lifestyle.
D) an open circulatory system.
E) parapodia.
Answer:
D) an open circulatory system.
Explanation:
In the given question, the characteristics of an organism are given which are:
1. Exoskeleton- outer covering composed of cuticle
2. system of tubes for gas exchange- do not respire but has tubes called trachea from which the air diffuses
3. modified segmentation- segmented bodies
All these characteristics show that the organism belongs to the Arthropods group of animals.
The Arthropods since having trachea for the diffusion of gas, therefore, possess an open circulatory system in which blood does not flow in the vessels but the open cavities in the body.
Thus, Option-D is the correct answer.
The principle is that adenine is always paired to thymine; and cytosine is always paired to guanine. In this particular sequence:
<span>3'-cgcatgtagcga-5'
The complementary leading strand will be:
5'-GCGTACATCGCT-3'</span>
