The answer is the first choice:
Negative feedback reverses a change in a variable that has moved outside of its normal range, whereas positive feedback strengthens it.
Feedback loops do not only apply to blood pressure. There are many examples from body temperature regulation to child birth to your AC unit at home.
The MRNA codon would be UCA
The DNA codon would be AGT
I think the correct answer from the choices listed above is option A. DNA contains deoxyribose sugar. DNA stands for deoxyribonucleic acid so it should contain such sugar. It is a molecule that contains genetic material used in organisms and other living things.
Answer:
Promoter is located upstream and terminator is located downstream relative to the transcription start site.
Explanation:
Transcription start site is the site from where the transcription starts which is denoted by +1. The sequence of nucleotides which is present backword to them called upstream sequence and nucleotide sequence which is present in the forward direction of transcription start site are called downstream sequence.
Promoter sequences are present upstream to the transcription start site and are denoted with a minus sign and terminator sequence is present downstream to the transcription start site.
Answer:
Cells produce energy by breaking down sugar and other molecules in the presence of oxygen to produce ATP. So the answer is "B".
Explanation:
The process of producing ATP in animal cells occurs through cellular respiration. Various processes occur in this which involve the presence or absence of oxygen. Glycolysis in the presence of oxygen leads to the production of two molecules of ATP. Glucose is broken down into pyruvate and water.
In citric acid cycle, acetyl coA is utilized to produce <u>2ATP, 6NADH and 2FADH molecules.</u>
Finally oxidative phosphorylation occurs in mitochondria. With the help of electron transport chain, ATP is synthesized by ATP synthase enzyme.
