Answer:

A protein-coding gene has an open reading frame (ORF) that make easier its identification

Explanation:

During translation, the messenger RNA (mRNA) is read by the ribosomes as triplets of nucleotides called codons in the open reading frame (ORF). An ORF can be defined as a gene fragment composed of codons which are translated into amino acids in a polypeptide chain. According to the genetic code, the information encoded by these codons will specify the sequence of amino acids in the protein, as well as the start codon and stop codons of the protein-coding genes. A start codon (AUG) is a site at which translation into protein begins, while stop codons (UAA, UAG, and UGA) mark the site at which translation ends. Moreover, non-coding RNAs (ncRNAs) don't have ORFs because they do not encode for proteins, and therefore their identification is more difficult.

This plant is not dangerous and can help treat cancer, this plant produces Curol, something that cannot be created in laboratory, so it will be a pleasure for me to preserve this plant it is a important plant that will save many peoples life in the future. There will be a treatment for cancer and families would stop crying after lost family that dies from cancer.

Compare each patient's cdna sequence to the wild-type cdna sequence. Each patient has one nucleotide-pair substitution mutation.

Lera25 [3.4K]

The mutation is a change in the nucleotidic sequence. In the exposed example, Patient 1: nucleotide 143, T<u>T</u>C⇒T<u>G</u>C. Patient 2: nucleotide 143, T<u>T</u>C⇒T<u>C</u>C. Patient 3: nucleotide 147, TT<u>C</u> ⇒ TT<u>G</u>.

<h3>What is a mutation?</h3>

A mutation is a change or alteration in DNI sequences that introduce new variants.

Many of these are eliminated, but some of them might succeed and be incorporated into each individual.

These mutations are the ones that have been selected by natural selection.

<h3>Solving the problem</h3>

We know that each sequence initiates with nucleotide number 103 and ends in nucleotide 162.

So first, we will number the nucleotides, from 103 to 162. Each nucleotide has a number in increasing order.

Now, we will identify the mutations in each of the strands by comparing them with the wild-type sequence. The mutation occurs in one of the nucleotides, so we must look for the change in the bases.

Finally, we will identify the nucleotide location of each mutation.

nucleotide wild-type mutated

<u> location nucleotide nucleotide </u><u> </u>

Patient 1 143 TTC TGC

Patient 2 143 TTC TCC

<u>Patient 3 147 TTC TTG </u>

Snakes can live up to 9 years. They slither up to 18 mph. Snakes are reptiles that are elongated, limbless, and carnivorous. Another interesting thing about snakes is that they don’t have eyelids. The last fact is that snakes can open there mouths up to 150 degrees so they can swallow there prey.
