2-an understanding that you are not perfect
Answer:
When helicase mutations occur, problems in DNA replication are found. The helicases are proteins that open the 2 strands of DNA to initiate the duplication, they are responsible for breaking the hydrogen bonds between the two DNA chains, thus separating the chains, also they have the function of repairing DNA mutations, if there is mutation in the gene that encodes them, various functions will be absent in the cell.
Deletion- the fact that a codon is missing implies that the nucleotides were deleted.
Answer:
Answer:
The correct answer would be "contains coded information for the creation of proteins".
DNA or deoxyribonucleic acid is a polymer of nucleotides.
It is the genetic material in most of the living cells present on earth. That is, it controls all the characters and traits of the living organisms.
In prokaryotes, it keeps floating in the cytoplasm whereas it is confined in the well-defined nucleus in eukaryotic cells.
The nucleotide sequence of the DNA is used as the code for the synthesis of the proteins.
It is first transcribed into the nucleotide sequence of mRNA which is further decoded into the amino acid sequence of the proteins.
Structurally, DNA and RNA are nearly identical. As mentioned earlier, however, there are three fundamental differences that account for the very different functions of the two molecules. RNA has a ribose sugar instead of a deoxyribose sugar like DNA. RNA nucleotides have a uracil base instead of thymine.
