Genetic information is transmitted from DNA to
Alexus [3.1K]


The best answer is D.

Genetic information for synthesis of a protein is transmitted from DNA to the ribosomes, which are the site for protein synthesis. This is facilitated by messenger RNA or mRNA in short.

In the nucleus of the cell, information from DNA is copied (transcribed) onto mRNA which leaves the nucleus and enters the cytoplasm where it attaches to the ribosome. The information on the attached  mRNA is  decoded and read ( translated) by transfer RNA (tRNA) which then brings corresponding amino acids to the ribosome to be linked together to form the protein.

You are examining the phylogenic relationship of a newly discovered plant species (Species 2). You amplify the RUBISCO barcode a
frozen [14]

Answer:

a. Inversion

b. Duplication

Explanation:

Inversion has the name suggest, has to do with a segment of DNA being reversed from end to end.

In this case here,

Inversion is taking place here.

species 1 ATGCAAATTTGGGCCCATGAATGGTTGCAA

species 2 ATGCAAAAATTTTGGTACGCCGAATGGTTGCAA

Therefore, the sequences in bold in species 1 are observed to be reversed end to end in species 2.

Deletion ❌❌

I am sure it's not feasible because deletion entails removal of a few sequences.

It can be seen that species 2 is longer than species 1, which gives another reason why deletion is not feasible too, as no sequences are seen to be deleted.

I believe duplication is feasible since AATT sequences are repeated once.

Our final answer,

inversion and duplication occur here.
