Answer: DF508 mutation. A Genetic, Hereditary, Autosomal and Recessive Mutation.
Explanation:
Cystic fibrosis (CF) is a recessive autosomal lethal disease, it is most common on Caucasoid populations. Its diagnosis is suggested by the clinical features of chronic obstructive pulmonary disease, persistent pulmonary colonization (particularly with mucoid Pseudomonas strains), meconium ileus, pancreatic insufficiency with or familiarity history of the disease. The FC gene is large, with about 250 Kb of genomic DNA, 27 exons representing about 5% of genomic DNA; encodes a 6.5 kb transcribed mRNA. This mRNA is transcribed into a protein of 1480 amino acid called CFTR (Regulator Transmembrane Conductance Cystic Fibrosis). When a three-base pair deletion, adenosine-thymine-thymine (ATT) identified in the CFTR gene, exon 10, it results in the loss of a single amino acid phenylalanine at position 508 of the protein. This mutation is called DF508; “D” stands for deletion and “F” for phenylalanine amino acid.
Neutrons have no charge. This means the nucleus of an atom is always positively charged. An atom has a neutral overall charge because it has the same number of electrons as protons.
The answer is <span>B. meiosis.
All cells in an organism are diploid (2n). Only reproductive cells are haploid cells (n). Mitosis is a division of a cell into two daughter cells identical to the mother cell. Meiosis is a cell division during which the number of chromosomes is reduced by half (from 2n to n). So, reproductive cells (n) are created by meiosis.
Cytokinesis is the phase during mitosis and meiosis.</span>
Answer:
Day 10
Explanation:
If the number of bacteria increases by a factor of two each day (i.e. it doubles), it will reach 5120 by day 10. At this rate, the colony likely started with 10 bacteria on day one and doubled each day to reach 320 by day 6.
Day 6- 320 bacteria
Day 7- 320×2= 640 bacteria
Day 8- 640×2= 1280 bacteria
Day 9- 1280×2= 2560 bacteria
Day 10- 2560×2= 5120 bacteria
Answer: I think that the reason to this is because the oxygen abundance was too low, the competition for food and other resources was too high, so there could be fish the would be filtered out and be killed.
