Drag each label to the correct location on the punnett square. the punnett square illustrates a cross for flower position in the pea plant. the phenotypes and genotypes of the parents have been given. the allele for axial position is dominant and represented by a. the allele for terminal flower position is recessive and represented by a. what is the genotype of the offspring? heterozygous homozygous recessive homozygous dominant

Hello :3 :3

Your question is related to genetics.

Taking a look at your question, A is dominant and axial, while a is recessive and terminal.

If you cross-breed these two pea plants, and you drew the Punnett square, you would end up with Aa (100%) heterozygous on the F1 generation.

Now, on the F2 generation, you would end up with                                                                                                     AA (25%) - Aa (50%) - aa (25%).  AA is homozygous dominant, Aa is heterozygous, and aa is homozygous recessive.

Based on the phenotypes and genotypes of these offspring, it is clear that the purple flower color allele is DOMINANT and the parents are HOMOZYGOUS RECESSIVE.

Explanation:

enzyme speed up the reactions

transcription is a process in which information is rewritten. it is something our cells must do, in a more specialized and narrowly defined way. in biology, transcription is the process of copying out the dna sequence of a gene in the similar alphabet of rna. it needs to happen in the nucleus because that's where the dna is. dna is always inside the nucleus unless the cell is dividing.

transcription is the first step in gene expression, which involves copying a gene's dna sequence to make an rna molecule. transcription is performed by rna polymerases. it has three stages: initiation, elongation, and termination. rna molecules must be processed after transcription in eukaryotes.

explanation:

long version:

the protein synthesis consists two processes which are, transcription and translation. transcription takes place in the nucleus. it uses dna as a template to make an rna molecule. rna then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs. transcription is the first part of the central dogma of molecular biology: dna → rna. it is the transfer of genetic instructions in dna to messenger rna (mrna). during transcription, a strand of mrna is made that is complementary to a strand of dna.  

these three stages are:

  initiation: in which   is the beginning of transcription.occuring when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

    elongation: in which is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

    termination: in which is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.
