Verdadero o falso mediante el genotipo podemos determinar si existen dominancia en una característica
Murljashka [212]

Answer:

Verdadero

Explanation:

Sabemos que los caracteres dependen de los genes. Y los genes pueden presentarse en forma de alelos dominantes, o alelos recesivos. La expresión de los alelos recesivos son enmascarados o escondidos por el alelo dominante. Es decir, que si ambos alelos se encuentran juntos en un heterocigota, solo el alelo dominante se expresará.

Entonces el alelo dominante expresa la característica que resulta dominante, mientras que el alelo recesivo expresa la característica recesiva.

Genotipo:

  • Homocigota dominante ----> Expresa caracter dominante (Solo el alelo dominante esta presente)
  • Heterocigota -------------------> Expresa el caracter dominante (Ambos alelos estan presentes, pero el dominante es quien se expresa)
  • Homocigota recesivo --------> Expresa el caracter recesivo (solo alelos recesivos estan presentes)

Por ejemplo, si tenemos dos fenotipos rojo y amarillo, y sabemos que el color esta codificado por un gen dialelico llamado M. También supongamos que no sabemos qué alelo expresa qué color. Teniendo solo estos datos, no podemos decir si el rojo es el color dominante o si el amarillo lo es.

Sin embargo, si tenemos los siguientes genotipos acompañando esta información:

  • MM--> Amarillo
  • Mm--> Amarillo
  • mm --> Rojo

Recién ahora podemos deducir que el caracter dominante es el amarillo.

Cite the three main types of RNA and describe briefly the function of each.
sveticcg [70]

Answer:

mRNA: Carry genetic information from DNA to protein; serve as template for protein synthesis.

tRNA: Serves as adapter molecule and deliver specific amino acid from the cell pool to the mRNA-ribosome complex.

rRNA: Structural component of ribosomes.

Explanation:

There are three types of nongenetic RNAs: mRNA, tRNA, and rRNA.  

1. The messenger RNA (mRNA) is formed by the process of transcription in the nucleus. Transcription uses template strand of DNA to specify the nucleotide sequence in mRNA. The mRNA enters cytoplasm to join ribosomes. The nucleotide sequence of mRNA serves as a template and specifies the amino acid sequence of proteins.  

2. The transfer RNA (tRNA) serves as an adapter molecule during the process of protein synthesis and binds to the specific amino acids to deliver them to the protein-synthesizing machinery. The anticodon of tRNA binds to the complementary mRNA codons.  

3. The ribosomal RNA (rRNA) serves as structural components for ribosomes. Each of the subunits of ribosomes is made up of rRNA and proteins.

Before starch can enter a cell, it must be
SOVA2 [1]

Answer:

C.

Explanation:

Starch are macromolecules that are made of monomers that are simple sugars. Cells are microscopic and they can only absorb small substances. Therefore starch needs to be digested in other words broken down into simpler substances that can be taken in by cells. Therefore before starch can enter a cell it must be 3) digested to form simple sugars
