The dominance pattern of a gene can be determined from the phenotypes of the parents and offspring. In the examples below, assum
Usimov [2.4K]

Answer:

A-complete dominant

B-codominance

C-Incomplete dominant

D-codominance

E-Incomplete dominance

Explanation:

Complete dominance- This is when a dominant Allen completely mask the effect of a recessive allele and the offspring express its phenotype E.g . A pea plant with all purple flowers and a pea plant with all white flowers produce a pea plant with all purple flowers.

Incomplete dominance- This occur when the dominant allele doesn't fully dominate over the recessive allele and the offspring shows a combination of both allele(a phenotype different from the parent)

E.g A red snapdragon and a white snapdragon produce a pink snapdragon.

Codominance- This occur when both allele express itself. The phenotype of the offspring consists of both allele example AB blood group

During DNA replication, the short sections of new DNA, known as Okazaki fragments, which are eventually linked together by ligas
Marianna [84]

Answer:

The correct answer is- lagging strand

Explanation:

During the DNA replication both the strands acts as template strand and DNA polymerase replicated both the strand. During this replication, one strand is replicated continuously which is called the leading strand and another strand is not synthesized in a continuous manner.

So small DNA fragments are formed due to discontinuous replication of DNA which is called Okazaki fragments. These fragments are then joined by DNA ligase and the strand is called lagging strand.  

Therefore the strand which is synthesized in a discontinuous manner is called lagging strand.

After differentiation, the various types of cells become specialized for a specific function. Their ______ relates to this _____
kykrilka [37]

Explanation:

The structure relates to their function

Their structural components (i.e. their makeup) determine their function (what they do). In specific cell types, collected proteins may function as a unit called an organelle.

Further Explanation:

In all eukaryotic cells mitochondria are small cellular organelles bound by double membranes make most of the chemical energy required for powering the biochemical reactions within the cell. this chemical energy is stored within the molecule ATP which is produced.

Some organelles are bound by membranes like those that make up the external structure of the cell, with varying compositions of phospholipids and proteins. These are advantageous, as they

  • may increase metabolic reaction efficiency;
  • they allow cells to concentrate smaller fractions of enzymes and solutes separate proteins and molecules that may harm the cells by parceling them into membrane-bound organelles
  • for example, hydrolytic enzymes concentrated within vacuoles may degrade macromolecules like DNA and RNA within the cytoplasm.

Identify all correct statements about the basic function of fermentation. Select all that apply.a. The basic function of ferment
DENIUS [597]

Answer:

The correct answer is option  c. "The basic function of fermentation is the regeneration of NAD , which allows continued ATP production by glycolysis".

Explanation:

For bacteria, the basic function of fermentation is not the production of ATP or ethyl alcohol, the basic function of fermentation is the regeneration of NAD+ , which allows continued ATP production by glycolysis. Bacteria normally uses glycolysis for ATP production, it only undergoes fermentation in the absence of oxygen. During bacterial fermentation, a small organic compound as an electron acceptor is used for NADH and regenerates NAD+, this NAD+ is later used in glycolysis for ATP production.
