2026 COMPLETE QUESTIONS AND
CORRECT ANSWERS GRADED A+
●● If a parent cell has 24 chromosomes how many chromosomes will
the daughter cell have after meiosis.
Answer: 12
●● a cell with only one set of chromosomes is a ______.
Answer: haploid
●● a cell iwth two sets of chromosomes is a ______.
Answer: diploid
●● what is the job of DNA.
Answer: contains genetic code and instructions for making proteins
●● mRNA contains what order compared to the original DNA strand?.
Answer: same order but replaced T's with U's
●● Which cycle of virus's (lytic or lysogenic) causes host cells to burst?.
Answer: lytic
, ●● how does DNA replicate itself?.
Answer: hydrogen bond is broken by the enzyme DNA polymerase and
it unzips, free nucleotides pair with phosphate bases and it zips back
together
●● how does RNA differ from DNA.
Answer: RNA can leave nucleus, has ribose sugar, and is a single strand
●● function of tRNA.
Answer: brings amino acids to ribosome for translation
●● funciton of mRNA.
Answer: carries genetic message from nucleus to ribosome
●● what happens in transcription.
Answer: make RNA from DNA, RNA polymerase enzyme unzips DNA,
mRNA nucleotides attach to one side of DNA, mRNA leaves nucleus
●● what happens in transcription.
Answer: rRNA attaches to mRNA, tRNA brings amino acids to first
codon on mRNA, anticodon on tRNA link up with codon on mRNA,
peptide bonds form and polypeptide chains then released into cytoplasm
and form proteins
