We would expect that a 15-nucleotide sequence that includes a stop codon at the end (as part of the 15-nucleotide sequence) will
kirill [66]

Answer:

4 amino acids.

Explanation:

To become translated into protein, a sequence is read in triplets called codons.

Each codon that codes for an amino acid is made up of 3 nucleotides.

Therefore, a sequence of 15 nucleotides would be translated into a polypeptide that is made up of 5 amino acids. (15 divided by 3 = 5)

However, we are told that there is a stop codon at the end of this sequence.

A stop codon is a specialised codon that does not code for an amino acid, but tells the protein machinery that the polypeptide is complete.

Therefore, the polypeptide would have 5-1 amino acids, which corresponds to 4 amino acids.

A gardener crosses a true-breeding tall tomato plant bearing red fruit with a true-breeding dwarf tomato plant with yellow fruit
Lemur [1.5K]

Cross of true breeding dominant and recessive tomato plants will have:

Phenotype ratio in F1 generation is 4:0

genotype ratio in F1 generation is 4:0.

Explanation:

Data given:

Tall vine = dominant TT

dwarf vine = recessive tt

red fruit dominant  RR

yellow fruit recessive   rr

true breeding tall tomato plant bearing red fruit is TTRR

true breeding dwarf tomato plant bearing yellow fruit = ttrr

the cross is shown in punnet square:

      TR       TR

tr    TtRr    TtRr

tr  TtRr    TtRr

the phenotype ratio- 4:0

the genotype ratio - 4:0

The phenotype is tall vine with red fruit

Genotype is all the progeny are heterozygous dominant.

Why do you think scientists want to be able to forecast space weather?
DiKsa [7]

Answer:

Scientists would most likely want to forecast space weather in order to know if it is safe for not only to lift off into outer space, but to be able to help astronauts in any case of emergency if something were to happen in the future.

Such as debris of small rocks that could pass by, so then astronauts would have to stay in the shuttle. To be protected from it.

In any case, scientists want to forecast the weather in outer space in order to protect astronauts, from any incoming dangers.
