It reveals that they have relationships of being friends.
Answer:
With the invention of the PCR technique , DNA profiling took huge strides forward in both discriminating power and the ability to recover information from very small or degraded starting samples.
The process of PCR mimics the biological process of DNA replication but confines it to specific DNA sequences of interest.
In PCR process , the DNA sample is denatured into separate individual polynucleotide strands through heating. Two oligonucleotide DNA primers are used to hybridise to two corresponding nearby sites on opposite DNA strands. Thus two new copies of the sequences of interest are generated.
Repeated denaturation , hybridisation and extension in this fashion produce an exponentially growing number of copies of the DNA of interest.
Quantitative PCR methods enable automated , precise and high - throughput measurements.
Answer:
The correct answer is letter D. Conventional breeding
Explanation:
In conventional genetic improvement a plant is crossed with another of the same species, with no incorporation of genes from another organism into the plant's genome, requiring repeated crossings until reaching the desired improved cultivar. Only in transgenics or genetic engineering are genes from another organism incorporated into the plant's genome.
A branch point on a phylogenetic tree is a separation point, from where a lineage is evolved into a new different lineage. The basal taxon is the unbranched lineages which evolved from the root.
Answer:
razonamiento
Explanation:
La ciencia se define como una agrupación de conocimientos racionales, lógicos, comprobables y sistemáticos los cuales son obtenidos mediante el proceso de observación/experimentación y posterior razonamiento. Los conocimentos científicos permiten deducir principios y leyes que son utilizados para predecir fenómenos del mundo natural. Una característica clave de la ciencia es el uso del razonamiento lógico mediante el cual aplica el método científico para generar dichos principios y leyes. El razonamiento lógico es un proceso mental que comienza con una premisa y finaliza con una conclusión comprobable que puede determinarse como verdadera o falsa.
