Explanation:

Genomics refers to the scientific study of genes (DNA) found in living organisms such as humans and animals.

A genome can be defined as the complete set of hereditary instructions that is typically found in the deoxyribonucleic acid (DNA).

Genome imprinting can be defined as an epigenetic biological process in which a genomic domain or genes of a living organism is marked biochemically with information that is related to parental origin. Thus, it is a non-Mendelian inheritance i.e genome imprinting is typically independent of Mendelian inheritance.

Transcription can be defined as a process which typically involves re-writing the informations contained within a Deoxyribonucleic Acid (DNA) into a Ribonucleic Acid (RNA) by enzyme RNA polymerase.

Although, the number of genes contained in the human genome is surprisingly low in comparison with less complex organisms such as bacteria, protozoa, salmonella, etc.

However, the number of possible products from those genes is greatly amplified by alternate arrangements of exons from a primary transcription.

An exon refers to the coding portion of a gene that contains the information required for transcribing and translating (encoding) the final part of a mature RNA, after one or more DNA sequences (introns).

Simply stated, an exon is a nucleotide sequence in DNA and RNA used for encoding a part of the final mature RNA.

A nucleotide can be defined as an organic molecule which forms the building block of nucleic acid such as deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).

spiders belong to a group of arachnids.

arachnids have the following traits :

they have two body parts.

they have eight legs unlike insects which have 6 legs.

they have no wings.

these traits distinguish them from insects.

the information that antonio is doubting us the statement that spiders differences are as a result of being first to evolve.

this is because the evolution of one species is independent of the other species.
