Think it's C since joints connects two bones together and marrow is inside bones.
Answer:
Methionine
Explanation:
The amino acid Methinoine is the start codon for all proteins, and can only be coded for with the codon AUG.
Answer: False
Explanation:
This is a false statement because researches have shown that Adrenaline is helping and it is good for long-term memory and if we have lots of Adrenaline that is making our brain work and remember better and more.
If we are recalling being insulted, falling, or something more, we can still retrieve those memories because of the Adrenaline and that means that it is not decreasing the ability to remember the trauma.
A) DNA fulfils all three conditions:
<span>(1) copy itself precisely - in the process of replication, DNA copies itself and two molecules of DNA are formed. This process is very precise thanks to the great number of proteins involved in these process that prevents error occurring and proteins that can fix the error if it occurs.
(2) be stable but able to be changed - DNA is very stable molecule otherwise, it cannot be a genetic material. However, its chains can separate in a short length so the translational machinery can attach to it and the process of transcription can occur. Also, in crossing over, during meiosis, </span>the exchange of genetic material occurs and chromosomes change a bit.<span>
(3) be complex enough to determine the organism’s phenotype - it contains a number of genes responsible for different traits. All of this results in the </span>organism’s phenotype.
B) DNA copies itself. <span>Meselson and Stahl conducted the experiments on DNA replication in which they used </span>E. coli<span> bacteria as a model system. After they labelled all bacteria's DNA with heavy 15N by using medium with heavy 15N, they switched bacteria to medium with light 14N. After several generations, all bacteria's DNA was labelled with light 14N. This experiment evidenced that the self-replication of DNA is semi-conservative process.</span>
