Answer:

<em>The correct option is A) The cell theory is the result of explanations of scientists' observations and not a  description of the cell structure as it relates to the function.</em>

Explanation:

The cell theory can never become a law because Scientific theories are well-tested explanations, while laws are well-tested descriptions of  natural phenomena; one cannot become the other.

A scientific theory is subjected to be changed overtime but a law cannot change. We have observed many changes in the cell theory in the past and we might find changes in this theory in the future also. Hence, the cell theory can never become a law.

TACATCCATCAGTTACGC A guanine replaced the 1st Thymine in the original DNA strand above, how many amino acids would be changed as
Julli [10]

Answer:

One amino acid

Explanation:

This question is describing the occurrence of the process of mutation, which is the alteration in the genetic sequence of a gene. In this question, a DNA sequence was given as follows: TAC-ATC-CAT-CAG-TTA-CGC. However, a SUBSTITUTION MUTATION took place in such a way that the thymine base was replaced by a guanine base to have mutated sequence: GAC-ATC-CAT-CAG-TTA-CGC.

Since the mutation is a kind of substitution mutation, only the codon affected by that mutation will change. This DNA sequence will be transcribed into a mRNA sequence. The mRNA will be read codon by codon (a group of hree nucleotides) to produce amino acid. Since one codon will be involved, one amino acid will be affected.

Describe the relationship between organic compounds, nucleotides, RNA, and a universal genetic code.
makkiz [27]

Answer:

Organic compounds→ nucleotides→ RNA→ universal code.

Organic compounds are the compounds made by living organisms with at least one molecule of carbon linked to different elements like hydrogen, oxygen, or nitrogen.for example: nucleotides.

A nucleotide is the monomer units of nucleic acids- DNA and RNA. Each nucleotide is made up of organic compounds- sugar, a phosphate molecule and nitrogenous bases (adenine, guanine, cytosine, thymine and uracil).  

The arrangement of nitrogenous bases in DNA decides the fate of proteins as the sequence of these bases acts as code arranged in the triplet called "codons" which code for specific amino acids.

Thus, Organic compounds→ nucleotides→ RNA→ universal code is the correct answer.
