Biology Questions and Answers
Protein Synthesis......................................................................................................................
- What is the genetic code?
Genetic code is the key for the
conversion (and thus RNAof DNA nucleotidnucleotide sequencese sequences)
into amino acids sequences that will
compose proteins.
- Which is the biological
molecule that contains the
genetic information that is
transmitted hereditarily and
controls the cellular
functioning?
The hereditary molecule the cellular functioning is the DNAthat controls
(deoxyriboncontains information ucleic acid). Tfor proteinhe DNA
synthesis in cells.
- How are the concepts of
DNA, gene, proteins and
characteristics of living beings
related?
Characteristicchemical reactionss of organisms de that occur in pend onthem.
These reactions arenzymes, highly specific proteins. Everye catalyzed by (^)
protein of an organism is made from
information that are made accordicontained in RNA moleculesng to a template
sequence of nucleotides of a DNA chain.
A gene is a DNA polynucleotide
sequence that contains infthe production of a protein.ormation for
- What is the role of
messenger RNA and
ribosomes for the protein
synthesis?
The mRNA is produced within thcellular nucleus and migrates to thee (^)
cytoplasm where associated to
ribosomes it gamino acid sequences that will comuides the building of (^) pose
proteins. Ribosomes are sites for the
meeting and binding of mRNAtransfer RNA (tRNA), they are the and
structures where amino acids
transported by tRNA are united bypeptide bonds forming polypeptide (^)
chains (proteins).
- Of what subunits are
ribosomes are made?
Ribosomes are made of two subunits,
the smallThese subunits are made of ribosomic subunit and the large subunit.
RNA (rRNA) and proteins. Ribosomes
have thrand two ee binding sites,for tRNA. one for mRNA
