What would be first three amino acids in the protein formed from this gene? UTC GTU TTG

Andrews [41]

<h2>Answer:</h2>

The three amino acid will be Tyrosine, Asparagine and Lysine respectively to sequence.

<h3>Explanation:</h3>

UTC GTU TTG

First the thymine in the sequence is changed to A, adenine because in the mRNA only three types of nucleotides are allowed which are Adenine, thymine and Uracil.

So the sequence will be:

UAC GAU AAG

These codons will be read by tRNA producing the polypeptide sequence of amino acids which are as follow:

Tyrosine Asparagine Lysine.

The crispr system involves the cas9 enzyme, which identifies specific nucleotides to be cut using a(n) ________ molecule as a gu

bonufazy [111]

Answer:

RNA

Explanation:

CRISPR system was discovered by a Japanese scientist. Naturally bacteria and many other prokaryotes have CRISPR system in their genome which they use as a self defense against a pathogen which is invading them. It consists of inter spaced, short palindromic nucleotide repeats which encode a guide RNA (gRNA). This guide RNA (gRNA) recognizes the target sequence on the pathogen. The gRNA is followed by Cas9 enzyme which along with the gRNA plays a very important role in breaking genome of the pathogen. Once the target gene is cut down the rest of the DNA can be rejoined by non homologous end joining.

But nowadays, scientists are using this system for genome editing and incorporating desired gene between the two ends which are cut down by CRISPR Cas9 system.

When conducting scientific research, appropriate methods must be used to find information that is reliable and valid. Angela was

weeeeeb [17]

Answer:

D. Type in human immune system + HIV effects.

Explanation:

Since Angela is focusing more on the human immune system and the effects of HIV could have on it, the keywords combination that would produce the most relevant search result has to contain human, immune system and HIV effects.

Option A has human, body systems and HIV, immune is absent.

Option B contains immune system and human, no HIV effects.

Option C contains HIV and immune system, no human.

All the options are lacking in some ways and will not produce the most relevant search results.

The correct option is D. It has all the necessary keywords.

Which type of organism is characterized by having jointed appendages, ability to molt, and three sets of fused segments? echinod

mel-nik [20]

The members of the phylum arthropoda have jointed legs. the number of jointed legs are variable, may be three pairs as in cockroaches, four pairs in prawns and even hundred pairs in centipedes. Members of this phylum have ability to shed their their exoskeleton(molting) and body is divided into three fused segments - head, thorax and abdomen.
