What are two diffrences between replication and transcription?
Ghella [55]
Replication - The action of copying or reproducing something.
DNA replication of producing two identical replicas of DNA from one original DNA molecule.

Transcription - First step to gene expression, in which a particular segment of DNA is copied into RNA (especially mRNA) by the enzyme RNA polymerase. Both DNA and RNA are nucleic acids, which use base pairs of nucleotides as a complementary language.

1.) Transcription involved both DNA and RNA, whilst replication only involves DNA.
2.) Replication uses two identical replicas of DNA, whilst transcription is copied.

Suppose that ear length in rabbits is controlled by two additive genes, each of which has two alleles. A true-breeding female (a
PilotLPTM [1.2K]

Answer:

The ear length will be 11 cm.

Explanation:

To know about the ear length of F1 generation, we need to know that how much length in centimeters is contributed by each of the alleles. As we know, each allele has the same value for contributing to the effect of ear length, hence we can divide the ear length by 4 to get our results.

As 6 divided by 4 is 1.5 hence, the allele a and b contribute to 1.5 cm of the length of the ear.

6 divided by 4 is 4, hence the alleles And B contribute to 4 cm of the length of the ear.

The F1 generation will have AaBb genotype hence, the lenght will be 4+1.5+4+1.5 = 11 cm.

The diagram shows a simple lipid.
Evgesh-ka [11]

The correct answer is option A, that is, saturated.

The mentioned lipid is not a phospholipid, as it does not comprise a phosphate group at the terminal of the chain, and is not a triglyceride due to the absence of glycerol moiety.

Each carbon combined with the hydrogens forms the maximum number of possible C-H bonds, thus, there are no multiple bonds between the carbons. Hence, it can be concluded that the lipid is saturated.
