Explanation:
all living things are made up of cells.
Answer:
mRNA or messenger RNA goes to ribosomes to dictate the genetic information that it contains .
Explanation:
Ribosomes act as work benches during protein biosynthesis.mRNA also called messenger RNA binds with the smaller subunit of ribosome at the time of translation.
The bound subunit of ribosome reads the genetic information as codons containing three concecuetive nucleotides present in mRNA thus helping tRNA to bring the particular amino acid specific for that codon at the A site or attachment site of ribosome.
Thereafter ribosome moves to the next codon to bring another amino acid and so forth.
Thus mRNA helps ribosome to brings the amino acids at the translation site.
Answer:
D.
Explanation:
I think its D. sorry if its wrong
Explanation:
Reflexes do slow with age. Physical changes in nerve fibers slow the speed of conduction. And the parts of the brain involved in motor control lose cells over time.
Researchers found that the brain's response time begins to decline at age 24. The descent is a slow, but nonetheless, steady one.
