Answer:

The development of sharper visual acuity.

Explanation:

At one week after birth, they can see red, orange, yellow and green. However, babies see red as the first primary color.

Many advances in vision development take place in months two and three. Infants develop sharper visual acuity during this period, and their eyes are beginning to move better as a team. A child should be following moving objects at this stage and starting to reach for things he sees.

algol [13]

Confirm that the sample has both helicase and primase activities, but not the ability to synthesize DNA

  • The replisome is a multiprotein-RNA complex that is required for the replication of DNA. The replisome consists of different proteins which include:

            1. Helicase enzymes that unwind and separate the DNA strand

            2. Replication factor C (RFC), a DNA-dependent ATP that acts as an activator of DNA polymerase.

           3. Proliferating cell nuclear antigen (PCNA)

           4. DNA gyrase/topoisomerase that cuts and reseals DNA strands, which is essential for DNA synthesis.

           5. Primase enzyme that synthesizes short RNA fragments called primers.

          6. DNA polymerase III, an enzyme that catalyzes the polymerization of deoxyribonucleotides into a DNA strand.

           7. DNA ligases enzymes that form phosphodiester bonds at a single-strand break in DNA

  • A primosome is a multiprotein complex responsible for creating RNA primers on single-stranded DNA (ssDNA) during the replication process.
  • The primosome is composed of different primase and helicase enzymes. In<em> Escherichia coli</em>, it consists of PriA helicase, PriB, PriC, DnaB helicase, DnaG (encoded by the dnaG gene), DnaC and DnaT primase.
