When two genes from two different people are sequenced and aligned, it is discovered that there are multiple sequence difference
SSSSS [86.1K]

Answer:

The mutations lie at locations where they don't affect protein sequence due to degeneracy of the genetic code.

Explanation:

Genetic code is the set of the triplet codons each of which code for a specific amino acid. The nucleotide sequence of mRNA is read in the form of triplets during the process of protein synthesis and the respective amino acid is added to the growing polypeptide chain. The genetic code is degenerate. This means that more than one triplet code specifies one amino acid and some amino acids are encoded by more than one codon.

For instance, genetic codes CUU, CUC, CUA, CUG specify amino acid "leucine". Therefore, any change in the DNA sequence that replaces one code for the leucine with another would not affect the amino acid composition of the protein. This would result in the synthesis of proteins with the same amino acid sequence from both the wild type and mutated genes.

Explain the three mechanisms of heat transfer in Earth’s atmosphere.
MariettaO [177]

Explanation:

There are three ways heat is transferred into and through the atmosphere.

radiation. conduction. convection.

Radiation

Radiation is the transfer of heat energy through space by electromagnetic radiation.If you have stood in front of a fireplace or near a campfire, you have felt the heat transfer known as radiation. The side of your body nearest the fire warms, while your other side remains unaffected by the heat. Although you are surrounded by air, the air has nothing to do with this transfer of heat. Heat lamps, that keep food warm, work in the same way.

Conduction

Welding iron is transferring heat by conduction

Conduction is the transfer of heat energy from one substance to another or within a substance. Have you ever left a metal spoon in a pot of soup being heated on a stove? After a short time, the handle of the spoon will become hot.This is due to transfer of heat energy from molecule to molecule or from atom to atom. Also, when objects are welded together, the metal becomes hot (the orange-red glow) by the transfer of heat from an arc.

Convection

convection is the transfer of heat energy in a fluid. This type of heating is most commonly seen in the kitchen with a boiling liquid.

Air in the atmosphere acts as a fluid. The sun's radiation strikes the ground, thus warming the rocks. As the rock's temperature rises due to conduction, heat energy is released into the atmosphere, forming a bubble of air which is warmer than the surrounding air. This bubble of air rises into the atmosphere. As it rises, the bubble cools with the heat contained in the bubble moving into the atmosphere
