Answer:
The step in gene expression in the drawing model is identified as the step of transcription, in which part of DNA nucleotide is copied into a complementary sequence in RNA.
Explanation:
Transcription is a process that consists of the synthesis of a single strand of mRNA, from one of the DNA strands, which will be used as a template strand.
The enzyme responsible for the transcription process is RNA polymerase which, based on the nucleotide sequence of the DNA strand, will add complementary nucleotides to the mRNA strand following the rule of base complementarity:
<u>If DNA has: Complement in mRNA it is:</u>
Adenine Uracil (no thymine in RNA)
Thymine Adenine
Cytosine Guanina
Guanine Cytosine
In summary, a <u>part of the DNA is responsible for the synthesis of an RNA strand where its nucleotides will be complementary</u>, which is illustrated in the drawing model.
<em> The other options are not correct because replication, reproduction or translation do not correspond to the processes illustrated in the picture.</em>
Since one of the dogs is a heterozygous dog, it means that the dog isn’t completely have black fur. Yes, the dog has the gene, but he also has the recessive gene of yellow fur. Making his yellow fur gene be recessive and get covered by the black fur dominant gene. (Bb). With the other parent has pure yellow fur recessive gene (bb). The punnet square below explains more clearly what I mean.
This means that there is a 50/50 chance of getting some puppies with full yellow fur but there is another 50/50 chance of then having the dominant gene of black fur but still having the yellow fur gene hidden.
This means that there is a 50/50 chance of getting some puppies with full yellow fur but there is another 50/50 chance of then having the dominant gene of black fur but still having the yellow fur gene hidden.
