Sickle cell anemia is a disease that occurs when an individual receives a recessive allele for sickle cell from each parent. Assume that a woman who is a carrier for sickle cell marries a man who is free of the disease. What are the chances of this couple having a child with sickle cell anemia?

What might occur if no stop codons were created in RNA during the transcription process?
Protein synthesis would continue forever because amino acids would keep being added
In the peas Mendel studied, yellow seeds were dominant to green, and rounds seeds were dominant to wrinkled.
Considering the laws of segregation and independent assortment, if a plant is heterozygous for both round and yellow seeds, how many different allele combinations could be produced by this plant in meiosis?
4
This process occurs after replication and non-sister chromatids exchange gene segments to make new combinations of genes
crossing over
For the DNA sequence shown, the promoter sequence is located to the left of the written sequence. The promotor is a specific DNA sequence that is a secure initial binding site for RNA polymerase and other proteins called transcription factors to initiate transcription.
