Answer:

An unknown mitochondrial DNA (mtDNA) sample is matched to a sample of mitochondrial DNA (mtDNA) that was recovered at the scene.

Explanation:

Once a sample is collect, the mtDNA is then tested to see if it matches the mtDNA from the scene.

How does genetic information flow in an organisim
prisoha [69]

Answer:

DNA to mRNA to Proteins

Explanation:

The central dogma of molecular biology describes the flow of genetic information in cells from DNA to mRNA to protein. The genes specify the sequence of mRNA molecules, which in turn specify the sequence of proteins.The translation of this information to a protein involves three mRNA nucleotides( codons) that correspond to an amino acid in the polypeptide sequence.

During transcription, a DNA sequence is read by RNA polymerase, which produces a complementary, antiparallel RNA strand. If the transcribed gene encodes a protein, the result of transcription is messenger RNA (mRNA), which produces protein in the process of translation.

During translation, a cell decodes the mRNA and assembles the a new polypeptide chain. The tRNA translates the sequence of codons on the mRNA strand. The tRNA transfers a free amino acid from the cytoplasm to a ribosome, where it is attached to the new polypeptide chain. tRNAs continue to add amino acids to the new end of the polypeptide chain until they reach a stop codon on the mRNA. The ribosome then releases the completed protein into the cell.

Describe what you think is happening during photosynthesis.
boyakko [2]

Answer:

During photosynthesis, plants take in carbon dioxide (CO 2) and water (H 2 O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.

Explanation:

The energy for photosynthesis comes from light. Light energy is converted to chemical energy by chlorophyll. There are two sets of reactions, light dependent and light independent. The process mostly takes place in the chloroplasts of plant leaf mesophyll cells. Photosynthesis is the process where a plants uses the sun’s energy to turn light into chlorophyll. Plants produce oxygen during this process and utilize carbon dioxide. Photosynthesis is the single most important chemical process on the earth. Almost all plants needs the sun in order to survive Photosynthesis is the most important chemical process on earth – it provides food and energy for all living creatures who eat the plants that rely on this process to produce their food (glucose). · More than half (70%) of the world’s oxygen is produced by phytoplankton photosynthesis in the world’s oceans.
