<span>Point mutations are of two types: Substitutions of bases that are the change of one base of DNA by another. And Transitions that are replaced on a pyrrhic basis by another pyrrhic or a pyrimidine by another pyrimidine. Transversions: substitution of a pyrrhic base by another pyrimidine or vice versa. These mutations are negative because they affect only one of the nucleotides, and therefore, only one triplet of bases are affected. When the mutation does not affect the individual it is a silent mutation. Chromosomal mutations Changes in the structure of the diploid chromosomes, where one of the chromosomes has a mutation, will have another normal. They can hinder the process of meiosis in the carrier since it hinders the correct pairing of the homologous chromosomes. It would produce an unfeasible offspring or with mutations.</span>
B. The prefrontal cortex is used to plan complex cognitive behavior, personality expresison, and moderate social behavior.
Answer:
Urinary system filters your blood, removing waste and excess water.
Your digestive system breaks nutrients into parts small enough for your body to absorb and use for energy, growth, and cell repair.
The immune system is a complex network of cells and proteins that defends the body against infection.
Answer:
carbon dioxide + water → glucose + oxygen
Explanation:
Photosynthesis is the process that plants use to make food.
Think about what you need to grow a plant.
It needs <u>water</u> for sure.
Plants and humans both need air. Plants "breathe" in <u>carbon dioxide</u>, which is what we breathe out. (That's why people say to plant more trees, because they take in carbon dioxide.)
Plants use photosynthesis to make food. The food is called <u>glucose</u>, which is a form of sugar.
Plants "breathe" out <u>oxygen</u>, which is what we breathe in. (Remember trees give us oxygen.)
You might also see the equation as a formula:
CO₂ + H₂O → C₆H₁₂O₆ + O₂
Carbon (C) dioxide (O₂)
Water, or dihydrogen (H₂) monoxide (O)
glucose (C₆H₁₂O₆)
oxygen (O₂)
Answer:
a. Reduced siRNA-mediated mRNA degradation
Explanation:
The TRBP (transactivation response element RNA-binding protein) is an RNA-binding protein that forms the Dicer complex, which is involved in epigenetic pathways such as those mediated by the RNA interference (RNAi) mechanism. RNAi is a key process where small non-coding RNAs such as, for example, small interfering RNAs (siRNAs) and microRNAs (miRNAs) can inhibit target gene expression at posttranscriptional level by different mechanisms (including the degradation of target mRNAs). A null mutation of this cofactor will alter the Dicer complex, thereby also affecting RNAi pathways mediated by small interfering RNAs.
