It would be an absence of a chemical in a chromosome or DNA strand
Answer:
TRUE
Explanation:
The answer is TRUE an experiment can be reliable without being valid however, a test cannot be valid unless it is reliable .
Only bacteria have peptidoglycan in their cell walls
Answer:
According to the diagram and the interaction of the structures to express information in the cell, it is true that:
- Molecule B can be used to produce molecule A.
- Molecule A can be used to produce molecule C.
Explanation:
Molecule A is a double stranded DNA, molecule B is a strand of RNA and molecule C is an amino acid encoded by a codon.
The DNA is capable of splitting and from one strand producing the messenger RNA, in the process of transcription.
Messenger RNA contains a sequence of bases, and the set of 3 bases of RNA form a triplet or codon. A specific amino acid can be formed from a codon. This process is called translation.
The way in which molecules A, B and C interact is through the processes of transcription and translation, making it possible to use genetic information for protein synthesis.
The other options are not possible because:
- <em>Only DNA can replicate, RNA needs the transcription to be synthesized.
</em>
- <em>Molecule B and C do not interact so that the amino acids are together, but this depends on the sequence of bases in the RNA.</em>
