Answer:
1.a sequence of sugars, phosphates, and nitrogenous organic bases: Nucleic acid
2.a complex molecule containing the genetic code: DNA
3.a nucleic acid that participates in the synthesis of proteins: RNA
Explanation:
Nucleic acids are the biomolecules that are composed of a sequence of nucleotides. Each nucleotide has a pentose sugar, a nitrogenous base, and a phosphate group. There are two types of nucleic acid called DNA and RNA. DNA differs from RNA with respect to the pentose sugar and the presence of a thymine base. The sequence of the template DNA strand serves as a genetic code.
It is copied into the nucleotide sequence of mRNA during the process of transcription. The molecules of mRNA serve as a template for the synthesis of proteins when their nucleotide sequence is read in the form of genetic triplets.
Answer:
These pairs of genes then determine certain physical features or traits. The genes that you have in your body right now make up your genotype. This genotype then determines your physical appearance, which is called your phenotype. In this activity, you will be given two sets of chromosomes.
Explanation:
Answer: These changes can be caused by environmental factors such as ultraviolet radiation from the sun, or can occur if an error is made as DNA copies itself during cell division. Acquired mutations in somatic cells (cells other than sperm and egg cells) cannot be passed to the next generation.
