Question

answer the following questions on molecular genetics. darken the circle that corresponds to your answer choice.1. genes contain instructions for assembling which of the following?a chromosomesb carbohydratesc cellsd proteins2. which part of dna carries genetic information?a the phosphate-sugar backboneb the order of nitrogenous basesc the hydrogen bonds between nucleotidesd the deoxyribose sugar3. in an unmutated segment of dna, the thymine molecules will pair with an equal number of which type of molecule?a adenineb uracil5. which of the following is directly produced by the process of transcription?a proteinsb rna polymerasec rna moleculesd dna molecules6. during which of the following processes is messenger rna formed?a replicationb transcriptionc translationd mutation7. study the diagram below.

Explanation:

1. Genes are segments of DNA located on chromosomes, and they hold the instructions for making proteins.
2. Genetic information in DNA is stored in the specific sequence of its nitrogenous bases (A, T, C, G).
3. In DNA, adenine (A) forms hydrogen bonds with thymine (T) in a 1:1 ratio.
4. Transcription is the process where a DNA template is used to synthesize messenger RNA (mRNA) molecules directly.
5. Transcription is the biological process that produces messenger RNA from a DNA template.

Answer:

1. D. proteins
2. B. the order of nitrogenous bases
3. A. adenine
4. C. RNA molecules
5. B. transcription
