TACATCCATCAGTTACGC A guanine replaced the 1st Thymine in the original DNA strand above, how many amino acids would be changed as
Julli [10]

Answer:

One amino acid

Explanation:

This question is describing the occurrence of the process of mutation, which is the alteration in the genetic sequence of a gene. In this question, a DNA sequence was given as follows: TAC-ATC-CAT-CAG-TTA-CGC. However, a SUBSTITUTION MUTATION took place in such a way that the thymine base was replaced by a guanine base to have mutated sequence: GAC-ATC-CAT-CAG-TTA-CGC.

Since the mutation is a kind of substitution mutation, only the codon affected by that mutation will change. This DNA sequence will be transcribed into a mRNA sequence. The mRNA will be read codon by codon (a group of hree nucleotides) to produce amino acid. Since one codon will be involved, one amino acid will be affected.

Explain how bacterial cloning can help increasing the amount of DNA (DNA amplification) and when it is implemented in science or
Nezavi [6.7K]

Answer:

The process of gene cloning involve multiple steps. It involves many enzymes, bacterial cell, vector to produced an amplified number of cell and hence product.

The gene of interest is find and then it is carried into the bacterial cell by the help of vector.

The vector is then carried to get incorporated into the bacterial cell. In this way the bacterial cell starts replicating and the and the desired product is produced in high amount.
