Answer:

The elephant and the sheep exhibit higher sequence similarity because they are more closely phylogenetically related

Explanation:

The elephant and the sheep are mammals, while the crocodile is a reptile, being the mammals the most inclusive group among these three species and it appeared later in evolution. Mammals are organisms that have shared evolutionary features such as warm blood, they produce milk and have hair

Answer:

The elephant and the sheep are genetically closer to each other than they are to crocodiles.

Explanation:

Reptiles and mammals share a common ancestor. Mammals got separated from reptiles and evolved to explode different ecological niches.

The subclass Synapsid is a reptilian groups that precedes mammals in evolution. The therapsid order is an advanced group of synapsids and the direct ancestor of mammals.

Crocodiles are reptiles, while elephants and sheep are terrestrial mammals. According to phylogenetic evolution, crocodiles sheep and elephants share a common ancestor, but during evolution, the mammals' group (sheep and elephants) got separated from reptiles (crocodile).

Sheep and elephant got separated later in the evolution.

There are physical traits that confirm this.

Reptiles are cold-blooded animals,  have squamous skin, vertical pupils, they are oviparous so they lay eggs were the embryo develops,

On the other hand, mammals are warm-blooded animals, have hair in the skin, females have milk glands, and they are viviparous so the embryo develops in the placenta.

2. Most mutations are "silent." What does this mean?​
Zielflug [23.3K]

Explanation:

Silent mutations occur when the change of a single DNA nucleotide within a protein-coding portion of a gene does not affect the sequence of amino acids that make up the gene's protein.

Classify each RNA post-transcription processing event according to whether it occurs in prokaryotes or eukaryotes.
tigry1 [53]

'RNA is transcribed and translated in the cytoplasm', 'transcription produces an mRNA ready for translation' and 'RNA is proofread for errors' occur in prokaryotes, whereas '5′ cap, 3' poly-(A) tail and RNA splicing' occur in eukaryotes.

The prokaryotic cells (e.g., bacterial cells) do not contain cell nuclei, thereby the messenger RNA (mRNA) must be transcribed and translated in the cytoplasm.

During prokaryotic transcription, the RNA transcript is proofread for errors. In bacteria, DNA polymerases proofread the transcript by using their 3’ → 5’ exonuclease activity.

In eukaryotic cells, RNA processing consists of several mechanisms:

  • A 7-methylguanosine cap (5′ cap) is added to the 5′ end of the precursor messenger RNA (pre-mRNA).

  • A 3' poly-Adenine (A) tail is added to the 3' end of the pre-mRNA.

  • Both the 5′ cap and 3' poly-(A) tail protect the RNA transcript from its degradation by exonucleases.

  • Eukaryotic RNA splicing consists of the removal of non-coding regions called 'introns' and subsequent splicing of the protein-coding regions called 'exons'.
