What would happen if replication of chromosomes did not occur before cytokinesis?

The cell process would be most likely to abort, because the chromosomes failed to make it replication, therefore, the chromosomes probably would not make it to cytokinesis, or the two cells would have an uneven number of chromosomes.

Which trait did heterozygous individuals show in Mendel's experiment on pea plants?
aniked [119]

Answer:

The answer should be dominant

Explanation:

because heterozygous can be Bb (example) and the B would still be the  dominant one and it would cover the small b (it also depends on how the questions is being asked like if it was 2 heterozygous parents having an offspring or only about the offspring which was heterozygous)

Determine whether the characteristics describe DNA replication in prokaryotes only, eukaryotes only, or both prokaryotes and euk
SVEN [57.7K]

Explanation:

DNA replication is a process common to both prokaryotes and Eukaryotes with few differences and similarities.

<u>Differences:</u>

1. Origin of replication (ori) : is a sequence of the genome where initiation of replication takes place. Prokaryotes have only single ori while eukaryotes have multiple ori as the DNA is large in eukaryotes so require multiple or to replicate whole DNA.

2. Replication site: prokaryotes lack nucleus where DNA is present in the cytoplasm while eukaryotes posses nucleus which encloses DNA. Therefore, replication takes place in cytoplasm in prokaryotes while in the nucleus in eukaryotes.

<u>Similarities:</u>

1. Enzymes: both posses same enzymes for DNA replication like DNA helicase, primase, polymerase.

2. The direction of synthesis: the enzyme DNA polymerase synthesizes new strand of DNA in the same direction that is 5' to 3' direction.

Thus, marked answer in the table are correct answer.

Which statement is NOT correct?
aliina [53]

Answer: a. Heritability research is able to identify genes for particular behavior patterns.

Explanation:

Heritability is the ability of a trait to move from one generation to another. Heritability, sum of phenotypic (observable) variability that is due to human genetic variations in a population.

Heritability, in a general sense, is the ratio of variability for a trait or character in a population due to variations between genotypes and the overall phenotypic variation.

Hence, as genes identification is are the basis of heritability research, option "a" is incorrect.
