Proteins (Polypeptides with a unique amino acid sequence) are required to guarantee that the accuracy of replication is compatible with the low frequency of errors that is needed for cell reproduction Helicases unwind the two strands of parental DNA and creates the replication fork; single strands binding proteins keep the single strands from reuniting

Answer:

Helicases unwind the two parental DNA’s strands and creates the replication fork; single strand binding proteins keep the single strand from joining.

Further information:

• DNA replication: a biological method occurring in all living organisms that is the basis for biological inheritance

• Helicase: It is an enzyme that may unwinds the DNA helix ahead of the replication machinery.

• Origin of replication: a specific sequence in a genome at which replication is started.

Steps of DNA replication:

• During initiation, proteins fix to the source of replication while helicase unwinds the DNA helix and two replication forks are formed at the source of replication.

• During elongation, a primer sequence is added with complementary RNA nucleotides, which are then substituted by DNA nucleotides.

• During elongation the leading strand is made constantly, while the lagging strand is made in portions called Okazaki fragments.

• During termination, primers are detached and substituted with new DNA nucleotides and the backbone is stuck down by DNA ligase.

Purpose of DNA replication:

The purpose of DNA replication is to produce two duplicate copies of a DNA molecule. This is essential for cell division during development or repair of damaged tissues. DNA replication ensures that each new cell receives its own replica of the DNA.

Bacteria lack RNA-splicing machinery, which means they are unable to splice out introns from eukaryotic genes. To engineer a bac

taurus [48]

Answer:

<em>make a gene from the given mRNA without the introns.</em>

Explanation:

Introns can be described as the non- coding regions of DNA. As they are non- coding, they are spliced out from the mRNA so that only the coding regions can be translated.

If we know a nucleotide sequence, then we can make a gene from it without added the introns. We can consider an mRNA strand and make a complementary strand from it, excluding the intron regions. Then from the DNA produced, we can make an mRNA without the introns and insert it into a bacterium.

Millets have higher nutritional content than wheat and rice, so they are poised to make a comeback. Find out:

34kurt

Answer:

(a) The grains which are termed as millets are Amaranth, Barnyard, buckwheat, kodu, sorghum, bajra, Kangani, and Ragi.

(b) The following are the advantages of millet due to which they are given more preference than wheat and rice:

1. Millet's are free of gluten, a protein digestion of which is very difficult by the body.

2. When we compare the protein content of rice, wheat and millet, it is found that millet has high protein content.

3. In all aspects of components of nutrients called as carbohydrates, proteins, fats, minerals and vitamins, millet is in prime position and is also easy to digest.
