asambeis [7]

Answer:

The correct answer would be- 1:1:1:1.

Explanation:

According to the question the cross between the two pea plants with the genotype RrYy and rryy where R for round seeds and r for recessive form that expressed wrinkled seed character. The other character of this dihybrid cross is the color of the seds Y for green and y for yellow seeds.

The cross is shown in the image attached that suggests that phenotypic ratio would be 1:1:1:1 as RrYy, Rryy, rrYy, and rryy.

Thus, the correct answer is : 1:1:1:1.

A circular molecule of DNA contains 1 million base pairs. If the DNA synthesis at a replication fork occurs at a rate of 100,000
lakkis [162]

Answer:

<h2>5 minutes </h2>

Explanation:

1. In bidirectional replication;  there are two replication forks, and each proceeding at a rate of 100,000 (as given in the question) nucleotides per minute.  

2. So, by  the given rate of replication, we can calculate that, it would require 5 minutes for the circular DNA molecule to be replicated by bidirectional replication because each fork synthesize  500,000 nucleotides in 5 minutes ( 100,000 per minute) ( as given, in 5 minutes × 100,000 nucleotides per minute= 500,000 and by 2 forks= 1,000,000) within the time period.
