Answer: D. A prominent scientist uses the hypothesis that the universe is much older to guide a scientific investigation.

Explanation:

The scientific theory is the proposed description for the cause of a natural process. It is supported by the evidences that are the outcomes of the experimental trials.

A scientific theory can be modified by conducting the research using different methodology, technology and by molding the research question or hypothesis slightly different from previous research.

According to the situation, the scientific theory related to the primitive universe has given. Certain facts are available related to universe. Thus a hypothesis can be framed so as to prove the scientific theory by conducting the scientific investigation involving experimental trials. The results should be valid to be inclusive in modifying a theory.

Is the phenotype that corresponds to the HbS allele harmful, beneficial, or both?

horrorfan [7]

Phenotype is referred to as the expressed trait that is caused by a certain combination of alleles.

<h3>What is phenotype?</h3>

Phenotype is referred to as the expressed trait that is caused by a certain combination of alleles. We will recall that the HbS allele is responsioble for the anemia that results from sickle shaped red blood cells.

This phenotype is both harmfull and benefical in the sense that it leads to the agglutination of the red blood cells in individuals that have this phenotype and eventual crisis. Also, it is beneficaila in that nthose who possess this phenotype do not suffer from malaria in the tropics.

Tau is a microtubule-associated protein that plays a key role in the development of certain brain disorders. To analyze Tau expr

telo118 [61]

Answer:

1. transcription of Tau DNA in different directions.

4. different chemical modifications of Tau protein.

Explanation:

Tau gene transcribe in different direction which depends upon the animal age. This happens because at different age and developmental stage, animal produce different RNA binding proteins which leads to formation of alternative splice forms. This reaction is strengthen by the addition of phosphate and sugar molecules which again depending on developmental stage and time.

What would be the most likely effect on the transcription of the trp structural genes for the mutation scenarios provided? mutat

blagie [28]

Answer:

I've responded to each scenario individually, please see below:

1. mutation that prevents ribosome binding to the mRNA

No transcription occurs

2. 5' UTR mutation that changes region 1 tryptophan codons into alanine codons

Transcription when alanine is low

3. mutation that creates a stop codon in region 1 of mRNA 5' UTR

Transcription occurs, a truncated protein will be made during translation

4. deletions in region 2 of the mRNA 5' UTR

Transcription occurs, region 1 and 2 might get paired together

5. deletions in region 3 of the mRNA 5' UTR

Transcription occurs, region 3 and 4 could combine to form a hairpin loop structure

6. deletions in region 4 of the mRNA 5' UTR

Transcription occurs, region 3 and 4 could combine to form a hairpin loop structure

7. deletion of the string of adenine after region 4 of the mRNA 5' UTR

Transcription occurs, however, it will not be as stable a molecule because of losing its polyA tail

Hope that answers the question, have a great day!

What was the first step of aerobic cellular respiration to evolve? What evidence is there to support this ?

kozerog [31]

The first step of aerobic cellular respiration to evolve is glycolysis, the evidence that there is to support this is with through the cytosol of the cytoplasm in which this stage takes place as this is the process where glucose has been split in two molecules by the enzymes.
