Blood type is a genetically determined trait. Two siblings donate blood and find out their blood types. The brother is Type A an
rjkz [21]

Answer:

C

Explanation:

The brother has different alleles for the blood type gene than his sister does.  Blood type is inherited from parents like many other traits that can be displayed on a punnet square.  Depending on what the parents blood type alleles were, the brother and sister could have different blood types.  

A different number of chromosomes doesn't lead to different blood types, so D is wrong.  And A is incorrect because the number genes also does not affect blood type.  And I think the blood type genes are on the same chromosome, so B is wrong.  C is correct because blood type is inherited by alleles, and different alleles can cause different traits, such as blood types.

What are the changes that one can expect to observe as a plant tissue culture develops?
ahrayia [7]

The changes that one can expect to observe as a plant tissue culture develops is the development of new shoots and root.

<h3>What is a Culture?</h3>

This refers to the process in which microorganisms, living matter etc are grown in a specially prepared nutrient medium which are made up of different types of compounds.

In the case of a plant tissue culture, there will be new shoot and root formation due to the presence of nutrients in which the plants are exposed to for its growth and survival.

This is therefore makes changes in the shoot and root be the most appropriate choice.

What is true about the lagging strand during DNA replication?
BlackZzzverrR [31]

There are not only one but two correct option, which are A and B.

DNA polymerases begin their synthesis at many points of initiation. Following the binding of specific proteins, the double helix opens to allow startup.


DNA synthesis begins on RNA / DNA primers consisting of primase and DNA polymerase a. The replication continues in one direction: in this sense one of the two strands of the DNA ("direct" strand) is traversed by the enzyme in the 3 '→ 5' direction, which allows the synthesis of another strand in the direction 5 '→ 3'. The DNA-ligases then provide the link between the different fragments of the new DNA.


The synthesis of the other strand ("delayed" strand) is more complex because the enzyme travels this strand from 5 '→ 3'. The primase and DNA polymerase α synthesize 30 nucleotide primers in front of the replication zone, and the DNA polymerase constructs small DNA fragments in the 5 '→ 3' direction (approximately 200 nucleotides; Okazaki). Ribonucleases destroy the RNA / DNA primers of the previous fragment and the fragments are then linked together by DNA ligase.
