Answer:
Spiral Galaxies, Elliptical Galaxies & Irregular Galaxies
Explanation:
How did galaxies originate? Astronomers believe that after the big bang, the explosion which began the universe 10 billion to 20 billion years ago, gravity began to compress masses of free-floating gas. Two main theories, bottom-up and top-down, explain what happened next. According to bottom-up theories, clusters began to form and assembled together into the larger units we know as galaxies. Top-down theories suggest that galaxies formed first, and the stars and other objects within them were subsequently produced. They categorized different galaxies to maintain their tests from the other galaxies.
Option C:
B. wild-type 5-AUGCAUACAUUGGAGUGA-3 mutant 5'-AUGCAUACAUCUGGAGUGA- 3'
Explanation:
A frameshift mutation is a genetic mutation such that the triplet nature of gene expression by codons, the insertion or deletion occurs in such as way that it alters the complete sequence of 3 codon sets and can change the reading frame, resulting in a completely different translation from the original.
As it is pertinent to understanding that all genes are normally translated in sets of 3 codons, which typically describes and explain a unique amino acid sequence. Thus, if a frame shift mutation occurs, it can affect many amino acid sequences and finally the entire protein.
If we look at option B:
wild-type 5-AUG CAU ACA UUG GAG UGA-3
mutant 5’- AUG CAU ACA UCU GGA GUG A-3’
An insertion of a base Uracil showed at the end of 3rd codon which affected and altered the whole sequence of codon triplets. This changed all next codons and finally all next amino acids will be altered.
The first one is A.
The second one is B.
Hope this helped!

Explanation:After the transcription of the DNA is complete, the genes encoding the amino acids for the proteins are copied onto the mRNA strand. After this, this RNA strand moves out of the nucleus. The ribosomes attaches the mRNA strand to itself and the tRNA reads the codon and brings the amino acid to the ribosome and attaches it. This process is continued till the protein is formed. This process is known as translation.
Hence, translation should be shown to complete the protein synthesis model.
And that what u need to know XD
Answer:
The correct answer will be virus.
Explanation:
The virus is the infectious agents which cannot replicate themselves. these viruses contain a protein capsid surrounding the genetic material.
The genetic material in the virus could be DNA or RNA but do not have both as single-stranded or double-stranded forms.
A virus with RNA are common in nature and an only a limited amount of RNA or DNA can fit a capsid and the capsid along with genetic material is known as the nucleocapsid.
Since the specimens show RNA but not DNA it is a virus-like Ebola, polio, measles, therefore, the specimen is virus and is the correct answer.
