________ are enzyme used during replication to attach okazaki fragments to each other.
Effectus [21]

Answer:

DNA ligase

Explanation:

After Okazaki fragments (sequences complementary to the lagging strand of DNA) are produced, they must be joined together to produce a continuous strand. The Okazaki fragments are then joined up by DNA ligase, which catalyzes the formation of a phosphodiester bond between the neighboring nucleotides.

What are the advantages of knowing the diameter of the field of view at a given magnification
aliya0001 [1]

Answer:

If I can deternine the field-of-view diameter, it makes it easy for me to determine the size of an organism in the field of view.

Explanation:

The advantages of knowing the diameter of the field of view at a given magnification are that I can have a mental picture of the approximate size of how large the specimens are when I can’t certainly determine them with a simple ruler and the metric system. It also enriches me with a good concept of vital ideas of the size of my samples and the size of what’s the organism.

Why is the percentage similarity in the gene always lower than the percentage similarity in protein.
Galina-37 [17]

Answer:

Synonyms in the genetic code exist and some species only use one synonym to get the same amino acid. The reason why the percentage is low in gene is because it does not involve a lot of processes compared to the proteins which undergo mRNA and tRNA to be coded as amino acids.

There is a mutation in a promoter next to a gene such that rna polymerase can never bind. what steps must occur for the gene to
Pachacha [2.7K]
<span>UGAGCC

There are three principles to keep in mind when predicting the sequence of the mRNA produced by transcription of a particular DNA sequence.
The RNA polymerase reads the sequence of DNA bases from only one of the two strands of DNA: the template strand.The RNA polymerase reads the code from the template strand in the 3' to 5' direction and thus produces the mRNA strand in the 5' to 3' direction.In RNA, the base uracil (U) replaces the DNA base thymine (T). Thus the base-pairing rules in transcription are A→U, T→A, C→G, and G→C, where the first base is the coding base in the template strand of the DNA and the second base is the base that is added to the growing mRNA strand.</span>
