A nucleic acid that carries the genetic information in cells and some viruses,
consisting of two long chains of nucleotides twisted into a double helix and
joined by hydrogen bonds between the complementary bases adenine and thymine or cytosine and guanine.
Answer:
<u>C) They may provide selective advantages.
</u>
<u>D) Slight differences in the genetic code may have significant results.</u>
Explanation:
The genetic code is universal, and present in most living beings . Generally, in most living organisms, the same codons are assigned to the same amino acids.
DNA sequences make up genes that may have multiple variants, called alleles. DNA deoxyribonucleic acid, is transcribed into mRNA and then translated into amino acids that form proteins.
Natural selection mainly acts on phenotypes, which are dependent on proteins and the organisms's environment. Phenotypes conferring advantageous traits are favored by the selection process- these help groups of organisms evolve over time.
Explanation:
Monosaccharides are simple sugar molecules so they are individual sugar molecules and Polysaccharides are a combination of several sugar molecules
Answer:
In RNA the base thymine is essencially replaced by the base uracil. So the sequence TGAC in DNA would get copied into RNA as ACUG.
Adenine pairs with uracil in RNA like it pairs with thymine in DNA
