The p53 gene is a recessive tumor suppressor gene which functions as a key regulator for the cell cycle. In the event when only one p53 allele is mutated then the function of the p53 gene will persist and apoptosis (programmed cell death) will proceed if there are significant gene mutations in the cell. If two p53 alleles are mutated then the cell will not receive the signal to apoptose even with significant mutations and cancer will develop.
Answer:
Characteristics that have helped humans survive major changes in the environment are their brains and body. Human's social cooperation with tool making always increases.
Approximately 50% of human genome is composed of repetitive sequences. It contains approximately 3 billion of these base pairs that reside with 23 pairs of chromosome within the nucleus or our cells or called nucleotides. Genes in the genomes of invertebrates such as Drosophila is not like the human genes because the human genes contain more and larger introns than the genes in the genomes. The human genes are larger than the genes in the genomes. The genome sequence is ~99.9% similar in individuals of all nationalities. Complete set of deoxyribonucleic acid of a single cell of an organism or sequence for humans (Homo sapiens) is called Genome. It includes both protein-coding deoxyribonucleic acid genes and noncoding deoxyribonucleic acid.
Answer:
The marine environment supports a diverse range of sea life that is important for global biodiversity. A healthy marine environment supports our cultural and social well-being, and the ocean's resources contribute to our economy.
Explanation:
Our aquatic wildlife are important sources of food, energy, jobs, atmospheric oxygen, buffers against new diseases, pests, and predators, and protection against food shortages and global climate change. add jobs and promote tourism through the enjoyment of nature
