Answer:
d. Nucleus
Explanation:
the nucleus stores the DNA which is the genetic code for the organism.
Answer: The purpose of transcription is to move the information from the DNA to the ribosomes with the help of mRNA. Then we have translation it occurs on ribosomes and its purpose is to assemble amino acids into proteins.
Explanation:
the steps of transcription:
1. unzipping the DNA
2. build the RNA molecule
3. detach the mRNA molecule
4. rewinds the DNA molecule
If u want the steps of translation tell me :)
Species change over time. -The mechanism that produces the change is natural selection: the differential survival and reproduction of individuals based on variation in their traits. Natural selection acts on individuals but individuals do not evolve; their descendants do.
<span>Damaged dna is excised by endonuclease.
Three excision repair pathways exist to repair single stranded DNA damage: Nucleotide excision repair (NER), base excision repair (BER), and DNA mismatch repair (MMR).</span>
If a substitution changes the amino acid to a “stop,” it's called a NONSENSE mutation. frameshift, missense, silent or nonsense (hint: deletion or insertion will always be frameshift). Sickel cell anemia is the result of a type of mutation in the gene that codes for part of the hemoglobin molecule.
