Question

complete the paragraph.
most organisms use
genetic code. there are
different types
of dna nucleotides. within a gene, each group of three nucleotides specifies a certain
. copies of the instructions found in genes are carried by molecules of
from the nucleus to the ribosomes, where
are assembled.

Explanation:

1. All known cellular organisms use the universal genetic code, which is shared across nearly all life forms.
2. There are 4 distinct DNA nucleotides (adenine, thymine, cytosine, guanine).
3. A group of three DNA nucleotides (a codon) specifies a certain amino acid, the building block of proteins.
4. mRNA (messenger RNA) carries genetic instructions from DNA in the nucleus to ribosomes.
5. Ribosomes are the site where proteins are assembled from amino acids.

Answer:

1. universal
2. 4
3. amino acid
4. mRNA (messenger RNA)
5. proteins
