The correct answer is: c. Transcription
Transcription is the first step of gene expression in which DNA molecule is copied (transcribed) into RNA (mRNA) by RNA polymerase. The process of transcription is divided into three phases:
1. Initiation
• RNA polymerase with transcriptional factors bind to gene promoter
• RNA polymerase unwinds DNA double helix (transcription bubble is formed)
2. Elongation
• RNA polymerases adds nucleotides complementary to DNA
3. Termination
• RNA polymerase gets to stop codon (transcribes a sequence of DNA known as a terminator)
• Formed complementary RNA strand is released from DNA-RNA complex
Answer:
A diet combining legumes and cereals will have a good balance of essential amino acids
Explanation:
Cereals are grains that are rich in vitamins, carbohydrates, protein and other essential nutrients, they include wheat, rice, sorghum etc. Legumes include a wide range of seeds, fruits, nuts, vegetables that are rich in proteins, carbohydrates and other nutrients, examples include peas, beans, lentils etc.
Cereals and legumes are referred to as staple foods, they are usually used to complement each other because combining them will result in a good balance of essential amino acids. In cereals, lysine is a limiting amino acid but is usually in high amounts in legumes. However, in legumes cysteine, trypthophan and methionine are the limiting amino acids but are found in cereals. Therefore, this makes legumes and cereals complementary in the diet as it significantly increases the protein quality of the diet.
C because it really doesn’t matter if you wash your hands before because it is recommended to wash them after to prevent any infections or diseases
Dinosaur fossils had been known for centuries as "dragon bones" or the remains of giants, but it wasn't until Dean William Buckland of Oxford, England described the carnivorous "lizard" Megalosaurus<span> (in 1824) that they were formally studied as an extinct group of giant reptiles</span>
