Question:
The complete question has these options:
A) tRNA with anticodons is carrying amino acids to the ribosomes.
B) DNA polymerase is using both strands of DNA to produce multiple RNA molecules.
C) Ribosomes are reading mRNA molecules three nucleotides at a time to synthesis proteins
D) RNA polymerase is using a single strand of the DNA molecule as a template for mRNA production
Answer:
D) RNA polymerase is using a single strand of the DNA molecule as a template for mRNA production
Explanation:
During transcription, RNA polymerase uses DNA as a template to create a new molecule of mRNA via complementary base pairing
A) tRNA with anticodons is carrying amino acids to the ribosomes. - this is not evidence of transcription but is instead evidence of translation
B) DNA polymerase is using both strands of DNA to produce multiple RNA molecules. - this is false, DNA polymerase is the enzyme that performs DNA replication not transcription.
C) Ribosomes are reading mRNA molecules three nucleotides at a time to synthesis proteins - this is not evidence of transcription but is instead evidence of translation
D) RNA polymerase is using a single strand of the DNA molecule as a template for mRNA production - this accurately describes the process of transcription.
If a cell has 18 chromosomes the daughter cells would have 18 chromosomes after mitosis.
c. 18
<u>Explanation:</u>
Mitosis is the DNA replication process which maintains the number of chromosomes in daughter cells equal to number of chromosomes in parent cell. In the process the parent cell divides into two daughter cells having the same chromosome number as that of parent cell.
Meiosis is a process different from that of mitosis where each parent cell divides into four daughter cells having half the number of chromosomes present in the parent cell.
Since sex cells have to be haploid in organisms like human beings, it is the process of meiosis that takes place in reproductive cells.
