Answer:
Humans get the energy and matter they need to survive from the food they eat. The foods humans eat contain carbohydrates, vitamins, and protein. All of those components are broken down by the human body with the aid of digestion.
Answer:
<u>Temperature</u> is most likely the reason of protein unfolding (denaturation).
Explanation:
In the figure attached, coiled (3-dimensional) protein structure is changed to 2 dimensional structure in which protein is unfolded. This is most likely the result of heating proteins which destroys the hydrogen bonds and non-polar hydrophobic interactions that are necessary to establish the tertiary structure of proteins. Principally, increased temperature results in the increased kinetic energy of atoms within a molecule. If the amount of heat is sufficient to break the hydrogen bonds, protein molecule can unfold to 2D structure as shown in the figure.
False, each sex cell has one allele so when it combines with the opposing sex cell (depending on the gender) it fills in the gap.
Answer:
Regulatory sites e.g enhancers and silencers
Explanation:
Gene expression involves the synthesis of gene products usually proteins and RNA. However, a certain product might not be needed at all or in small quantity. Gene regulation mechanism is the process that makes this happen. Gene regulation is the mechanism that acts to induce or repress the expression of a gene.
Gene regulation involves controlling the rate and manner of gene expression which is achieved through a set of regulatory proteins called transcription factors. Transcription factors bind to specific regulatory nucleotide sequences and help to turn "on or off" specific genes in the DNA.
Transcription factors can either be ACTIVATORS or REPRESSORS depending on whether they boost or inhibit gene expression. The binding sites for these regulatory proteins called TRANSCRIPTION factors are the regulatory nucleotide sequences on the DNA called enhancers and silencers.
<span>For example, a prokaryotic cell is an uncivilized society while the eukaryotic cell is a more systematized society, with coordination and cooperation and a leader.
Eukaryotic cells has a nucleus while prokaryotic cells do not. Eukaryotic cells have more than one chromosomes and is usually multicellular while the prokaryotic cells has only one chromosome and it's not even a genuine one, only plasmids and has unicellular however some cyanobacteria maybe multicellular. Eukaryotic cells have genuine membrane-bound nucleus, lysosomes and peroxisomes while prokaryotic cells display just the opposite of eukaryotic cells. Eukaryotic cells recombines its genes by meiosis and by the fusion of gametes while the prokaryotes does by partial and undirectional transfer of DNA.</span>
