Answer:
75% probability
Explanation:
The father have the trait of sickle cell anemia which means he is a sickle cell dominant with a trait of dominant SS ( meaning he has displays the severe symptoms of sickle cell disease that occur in a person who has two copies of that allele i.e homozygous). While the mother is heterogygous which means that she has one abnormal allele of the hemoglobin beta gene represented as As.
Based on this notion, upon crossing of the traits the probabilities are<em> 75% Heterogygous trait and 25% homoxygous traits (i.e As, As, As, SS)</em>. Meaning 75% of the children will be unaffected by the Sickle cell anemia, while 25% will be affected by the anemia.
Answer: it is where cellular respiration occurs
Explanation:
Answer:
a, b, c are correct
Explanation:
Enhancers are DNA sequences that increase the rate of transcription. Enhancers act as binding sites for transcription factors that stimulate the transcription of one or more genes and enhancers stimulate transcription for specific cell type or tissue in a specific manner. The possible reasons for the lack of enhancers in bacteria include.
Enhancers often provide a mechanism for cell-specific transcription of genes, and most bacteria lack differentiated cell types.
Bacterial operons make coordinate regulation of protein synthesis by enhancers unnecessary.
There is little to no intergenic space on bacterial chromosomes, which makes long-range-acting enhancer sequences unnecessary.
Therefore, the correct options are (a), (b), and (c).
