Match the following terms with their best/ most reasonable descriptions: Group of answer choices self-propagating mechanism by w
Zigmanuir [339]

Answer:

1. Gene drive.

2. Consensus.

3. Clones.

4. Coverage.

5. Pharmacogenomics.

6. Sanger sequencing.

7. Sequence assembly.

Explanation:

Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.

Deoxyribonucleic acid (DNA) is an organic complex-molecular structure found in all living organisms. It comprises of genes and is essentially the foundation block of all living organisms such as humans, animals and plants.

The human somatic cell is made up of 46 chromosomes which are sub-divided into 22 pairs of autosomes and a pair of sex chromosomes (X and Y). An autosome is one of the numbered chromosome that is typically not a sex chromosome.

On the other hand, sex chromosomes (X and Y) are responsible for determining the gender or sex of living organisms such as humans.

The various terminologies used in the field of genetics and their respective description are matched below;

1. Gene drive: self-propagating mechanism by which a desired genetic variant can be spread through a population faster than traditional Mendelian inheritance.

2. Consensus: likely sequence of a piece of DNA.

3. Clones: replicated pieces or fragments of DNA.

4. Coverage: the number of unique reads that include a given nucleotide in the reconstructed DNA sequence.

5. Pharmacogenomics: study of how genes affect a person’s response to particular drugs.

6. Sanger sequencing: original method for determining the nucleotide sequence of DNA, also called "chain termination method."

7. Sequence assembly: aligning the sequenced fragments from a longer DNA sequence in order to reconstruct the original sequence.

What are the structures found in a root hair cell of a plant?
Licemer1 [7]
Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption. They also contain lots of mitochondria , which release energy from glucose during respiration in order to provide the energy needed for active transport.
