Answer:

What results from the addition or deletion of nucleotides in any number except a multiple of 3?
eimsori [14]
Addition or deletion of nucleotides in any number besides 3 results in a "frame-shift mutation."
This is because every 3 nucleotides of DNA/mRNA exons codes for a single amino acid in the synthesis of a protein. This triplet codon theory means that if 3 nucleotides are added or deleted then an amino acid will be added or lost, but subsequent codons and amino acids will still be read correctly.
However, if any number of nucleotides other than 3 are added or removed, then the codons following the mutation will be out of "sync," in terms of the reading order.
Hence it is called a frame-shift mutation because it shift the reading frame when translating nucleic acids into proteins. Frame shifts will lead to the wrong amino acids being adding in the wrong order for the rest of the code after the mutation.

Consider the terms egg, sperm, and sporophyte. Which term links egg and sperm directly to sporophyte?
NARA [144]

Answer:

Explanation:

La fecundación es el proceso por el cual dos gametos (masculino y femenino) se fusionan durante la reproducción sexual para crear un cigoto con un genoma derivado de ambos progenitores. Los dos fines principales de la fecundación son la combinación de genes derivados de ambos progenitores y la generación de un cigoto.

En el caso de las plantas con semillas pros, hay que diferenciar el fenómeno de la fecundación propiamente dicho (unión íntima de dos células sexuales hasta confundirse sus núcleos respectivos y, en mayor o menor grado, sus citoplasmas),1​ del proceso biológico que lo antecede: la polinización, en el que los granos de polen, desarrollados en las tecas que contiene cada antera de un estambre (hoja reproductora masculina), son transportados por el viento o los insectos a los estigmas, donde germinan emitiendo un tubo polínico que crece hacia el ovario. En este caso no se trata de gametos, sino de esporas, pues cada grano de polen contiene dos gametos o células reproductoras masculinas
